▼ Physicians and scientists have suspected that the testes secrete a substance into the body that causes male secondary sexual characteristics for hundreds of years. However, testosterone was not synthesized until 1935 and it was not until the 1940's when scientists could accurately measure the amount of this hormone in the blood. Since then, scientists have been able to make correlations between the levels of testosterone in the body and men's health Scientists have long observed higher levels of testosterone to be associated with an increase in levels of Hematocrit (Hct). As a result, Testosterone Replacement Therapy (TRT) has been used to treat anemia associated with chronic diseases. In recent years, prescription sales for testosterone have sky rocketed due to new clinical uses such as androgen deficiency in older men. In fact, the rate of prescription for testosterone products has increased by over 170% in the previous five years. Long-term data shows that the level of testosterone in the male body begins to decrease at about the age of 30. As the life expectancy of the general population continues to increase, TRT may be a viable option for older men with low testosterone to increase the quality and duration of life. However, an increase in Hct continues to be a major side effect of TRT. New research is beginning to make clear the mechanism by which testosterone affects erythropoeisis. New research suggests TRT suppresses hepcidin and leads to an increase in the rate of iron (Fe) retention in red blood cells (RBCs). Inter-individual differences in the pharmacogenetic effects of TRT have been observed. In the future TRT could be genetically tailored based on the individuals DNA. In this case, the optimal dose of testosterone can be given to maximize benefits and reduce side effects. Here, the risks and benefits associated with TRT and a review of the updated Clinical Guidelines for its use will be presented. The effects of TRT on erythropoeisis will be investigated via a review of the literature. The main objective of this review is to provide a general understanding of TRT and a major side effect of its use, excessive erythropoeisis.

▼ The effects of testosterone were studied on the tropical fish, Cichlasoma bimaculatum. Growth experiments were designed to determine how testosterone influenced the food consumption and growth of fish. Starvation experiments were designed to show the effects of testosterone on the basal rate of utilization of body energy stores and to establish what effect the anabolic steroid has when anabolism is reduced by the absence of metabolites from food. During the course of the experiments data were collected on wet weight, dry weight, fat, ash, protein and water content and on heat of combustion for control and testosterone treated fish. Four experiments were conducted where cichlids were starved, some as controls and some continuously exposed to testosterone 1:1,000,000. Wet weight, dry weight, weight of crude fat, weight of ash and the water content per cichlid usually decreased during starvation in controls and in the cichlids exposed to testosterone. Water content varied irregularly with reference to protein. Protein usually dropped where as water content dropped clearly in only one control experiment, did not alter markedly in two and increased in one. The testosterone treated fish tended to accumulate more water than did controls. Considerable variability was noted in the data. Much was due to an uneven distribution of cichlids with respect to weight among various groups and subgroups. Despite precautionary measures it was very difficult to maintain true starvation conditions. Some nonfilterable organic materials in the water as well as algae and minute insects may have been a source of food to the starving fish. More evident however, was the food made available as the result of the death of fish. On several occasions there was evidence of cannibalism, both in control and testosterone treated groups. The death of a fish, besides affording food to starving cichlids, introduced an error in the direction of increasing the average if a small fish died, and of decreasing the average if a Larger fish died. On the basis of calories disappearing during starvation, it was shown that starvation and starvation plus testosterone altered the composition of cichlids and decreased the heat of combustion per gram of cichlid. The testosterone treated fish were usually altered to a greater extent. Two growth studies were conducted where some cichlids were fed essentially ad libitum and utilized as controls, and others fed and continuously exposed to testosterone 1: 1, 000, 000. Dry weight in four out of six available comparisons was lower in testosterone treated fish than in controls; in one case the dry weights were similar and in one case the control cichlids had the higher dry weight. Protein was lower in five out of six available comparisons in the testosterone treated fish and were similar in one comparison. The control cichlids fed tubificids accumulated higher amounts of fat than cichlids fed and exposed to testosterone. The amount of food consumed per testosterone treated fish at each sample period was less than for the…

▼ Frailty can be broadly defined as the vulnerable health status that occurs in older adults. With the ageing population understanding frailty is becoming an increasingly important issue. While no consensus exists on the exact definition of frailty, two models have become prominent in geriatric research. These are the frailty phenotype, a model that measures frailty according to the syndromic aggregation of 5 physical criteria and the frailty index (FI), a broad index of age related health deficits. While recent years have seen a substantial increase in research into frailty, there remains a relative paucity of data from European studies and studies in men. Of the many mechanisms suggested to contribute to frailty there has been particular interest in the role of declining levels of anabolic hormones, partly because replacement of these hormones represents a potential strategy for managing this condition. The broad aim of this thesis was to explore the condition of frailty and its relationship to anabolic hormones, particularly testosterone (T) in ageing European Men. This project involved analysis of data from 2 studies: The European Male Ageing Study (EMAS), a longitudinal cohort study of 3369 men from 8 European centres and a trial of T treatment in 262 men with low testosterone and symptoms of frailty. A set of phenotypic frailty criteria were developed for use in the EMAS, using this model the prevalence of frailty was 2.6%. This increased with age from 0.1% in men aged 40-49 up to 6.7% in men aged 70-79. This model was compared against an FI, the correlation between the two models was moderate, r=0.41, and both models were related to incident falling at 2 year follow up; Ordinal OR (95% CI), 3.15 (1.75 to 5.66) for the frailty phenotype and 5.28 (3.35 to 8.32) for the FI in adjusted analyses. In the hormone analyses frailty was related to lower free T according to both models, Ordinal OR (95% CI); 1.19 (1.02 to 1.39) for the phenotype and β-coefficient (95% CI); 0.006 (0.003 to 0.009) for the FI (FI values range from 0-0.7). Free T was particularly related to the sarcopenia criteria OR (95% CI); 1.40 (1.09 to 1.80). Frailty was also related to LH, FSH and SHBG. Deficiency in multiple anabolic hormones was related to frailty, in adjusted analyses each additional deficiency was associated with an RRR (95% CI); 1.71 (1.38 to 2.13) increased risk of phenotypic frailty and a β-coefficient (95% CI); 0.016 (0.012 to 0.02) increase in FI score. The trial analyses focussed on a 6 month post treatment follow up phase. It was found that gains in lean mass and muscle strength were not maintained at 6 months post treatment. The adjusted difference between groups at 6 months post treatment for knee extensor strength was 4.0 (-3.9 to 11.9) Nm compared to 8.1 (-0.2 to 16.5) Nm at the end of treatment, similarly the difference in lean mass declined from 1.2 (0.8 to 1.7) kg at end of treatment to 0.3 (-0.1 to 0.8) kg at 6 months post treatment. In summary, the frailty phenotype was adapted and validated for use in the EMAS study.… Advisors/Committee Members: ROBERTS, STEPHEN SA, TAJAR, ABDELOUAHID A, Wu, Frederick, Roberts, Stephen, Tajar, Abdelouahid.

▼ Rugby union is a highly competitive and physically demanding contact sport in which successful outcomes rely, inherently, on strength, power, speed, and endurance. Resistance training is a potent stimulus for skeletal muscle strength and power adaptation, and training stimuli and loads modulate adaptation. Adaptive responses are mediated by cellular and molecular events, and actualised by alterations in gene expression. The steroid hormones testosterone and cortisol play a role in the adaptive process and subsequent training outcomes. This thesis investigates strategies intended to modify salivary hormone responses and affect resistance training outcomes. A literature review examined the cellular response of skeletal muscle tissue to resistance exercise with attention focussed on how testosterone and cortisol mediate adaptive outcomes. The acute testosterone and cortisol responses to complex training were investigated in Chapter Three. Sixteen rugby players performed four exercise protocols in a cross-over manner: power-power; power-strength; strength-power; or strength-strength. The most noteworthy responses were a small testosterone elevation and a trivial elevation in cortisol following the strength-power protocol, suggesting that this exercise sequence elicited an enhanced anabolic state compared to the other exercise protocols. An interaction between hormonal circadian rhythms and exercise stimulus was investigated in Chapter Four. Eight rugby players performed identical squat training over four weeks either in the morning or in the afternoon. Clear differences were observed between pre- and post-exercise hormone concentrations, and the ratio of testosterone to cortisol was elevated in the afternoon. Training resulted in similar increases in box squat strength regardless of time performed; however peak power increased to a greater extent when training was performed in the afternoon. This observation suggested that circadian rhythmicity has the potential to modulate specific adaptations to resistance exercise. The effect of the ultradian pulsatility of testosterone and cortisol, and their interaction with the hormonal responses to physiological and psychological stimuli, were investigated in Chapter Five. Testosterone and cortisol concentrations of seven males were measured every 10 min between 0800 and 1600 h on three consecutive days. Analysis was consistent with episodic testosterone pulses on non-intervention days. A sprint intervention elicited a small elevation in testosterone and this response correlated with the change in testosterone concentration in the 10 min prior to exercise. Thus, the testosterone response to exercise may be related to the ultradian biorhythm. This interaction could have important implications for adaptation to exercise. The ability of caffeine to modify the hormonal response to exercise was investigated in Chapter Six. A double-blinded, placebo controlled study with 24 athletes ingesting 0, 200, 400, or 800 mg doses of caffeine, assessed testosterone and cortisol responses to… Advisors/Committee Members: Gill, Nicholas (advisor), Ingram, John (advisor), Hopkins, Will (advisor).

A growing body of evidence indicates that testosterone (T) plays an important role in regulating patterns of growth in lizards. Testosterone has also been found to facilitate the development of male-typical coloration and a suite of male behaviors that increase reproductive success. However, while T promotes male fitness through these characteristics, it appears to hinder fitness through direct molecular inhibition of growth and through indirect potential costs associated with increased parasitism. The relationship between T and ectoparasitism is complicated by seasonal variation in host circulating T levels and ectoparasite life cycles. It is unclear whether sex differences in ectoparasite loads are present year-round, are present only when circulating T is high in males, or are present only when ectoparasite abundances are high. Furthermore, it is often assumed that because ectoparasites feed by taking nutrients and energy from their hosts, then ectoparasites likely impact host growth. Effects of ectoparasitism on host growth may be particularly high in males if they have greater ectoparasite loads than females. This could indirectly lead to slower male growth and smaller overall male body size. To address the lack of information regarding direct and indirect effects of T on growth, seasonal variation in sex- biased ectoparasite loads, and of the relationship between ectoparasitism and growth, I investigated (1) whether growth inhibition in eastern fence lizards (Sceloporus undulatus) is regulated through androgen or estrogen receptors, (2) seasonal correlations of mite loads with environmental mite abundances, and (3) whether sex differences in growth are correlated with sex differences in mite loads. I found that DHT inhibits male growth in S. undulatus, suggesting that T inhibits growth through direct androgenic molecular regulation. Furthermore, as indicated by the negative correlation between male growth and mite load, I found that T may also inhibit growth in males indirectly through costs associated with increased mite parasitism. Mite loads on S. undulatus varied seasonally, with peak mite loads occurring during months of high environmental mite abundance, coincident with seasonally high circulating T in yearling males and negatively correlated with male growth. This suggests that mites may impose a cost to growth in S. undulatus and contribute to male growth-inhibition, sex-specific growth rates, and the development of sexual size dimorphism (SSD).

▼ Abstract: It has been suggested that prenatal testosterone (PT) is positively related to intelligence or learning-ability skills. Digit ratio (2D:4D) is a negative correlate of PT. This study considered the correlations between 2D:4D and academic success in practical and theoretical disciplines in the Dental School curriculum of the Piracicaba Dental School, State University of Campinas, Brazil. Overall, 80 subjects (40 males and 40 females) aged between 18 and 22 years (means 19.5 ± 1.1 and 19.7 ± 1.2, respectively) had their right hand palm photographed by a digital camera attached to a standardising device, perpendicular to the surface. The images were transferred to a computer and the index and ring fingers were measured from the ventralmost crease up to the tip of the finger using Adobe Photoshop. Data were analyzed using Microsoft Excel and SPSS 16. Mean digit ratio was 0.980 ± 0.038 for males and 0.991 ± 0.025 for females. Digit ratio was correlated to the grades obtained by the students through their first four semesters. Theoretical and practical grades were significantly negatively correlated to digit ratio in males (and this was particularly so after the influence of age and hours of study were removed, p = 0.02 and 0.004, respectively), but not in females (p = 0.89 and 0.77, respectively). This finding supports a link between high PT and intelligence in males. The lack of relationship between 2D:4D and examination marks in female students, suggests that intelligence in females may be influenced by factors other than prenatal testosterone Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Jorge Junior, Jacks, 1962- (advisor), Universidade Estadual de Campinas.

BACKGROUND: Total testosterone in men decreasing with age is well-established. However, observations on aging-related decrease in total testosterone (TT) are not consistent. The aim of this study is to seek the relationship between testosterone and health status and investigate the influence of the chronic disease to testosterone level. METHODS: A total of 4,284 aged ≥ 40 year old men were included between 2008 and 2013. The subjects divided to two groups (chronic disease group versus normal group). Blood tests results and clinical data, including serum total testosterone, were checked and compared between the groups. RESULTS: Our data showed that 2,041 subjects had chronic diseases (47.6%), and 2,243 were normal (52.4%). Total testosterone and age(r=0.032, P=0.034), HDL(r=0.133, P<0.001) had positive correlation, respectively. On the other hand, BMI(r=-0.198, P<0.001), waist circumference(r=-0.184, P<0.001), blood pressure, ALT(r=-0.132, P<0.001), fasting sugar(r=-0.105, P<0.001), Triglyceride(r=-0.119, P<0.001) and albumin(r=-0.108, P<0.001) showed negative correlation with total testosterone, respectively. Total testosterone level did not decrease with age. People who had metabolic syndrome, hypertension and diabetes were had lower total testosterone than normal population. Odds ratio of the hypogonadism in chronic disease group compared to normal group was 1.595(95% CI, 1.355-1.876, P<0.001). CONCLUSION: The total testosterone level was lower in chronic disease group compared to healthy subjects. Total testosterone level influenced by disease status, not by aging.

1) 연구배경: 일반적으로 테스토스테론은 나이가 들수록 감소한다고 알려져 있다. 하지만 최근의 연구에 따르면 테스토스테론의 감소 및 남성갱년기는 노화와의 연관성 보다는 만성질환을 포함한 다른 조건에 의할 것이라고 조심스럽게 언급되고 있다. 그러므로 본 연구는 남성호르몬에 영향을 주는 주요 인자 중 질환에 의한 영향을 알아보고자 한다. 2) 방법: 2008년부터 2013년까지 40세 이상의 남성 4,283명을 대상으로 질병군 및 정상군으로 나누어 총 테스토스테론을 포함한 혈액검사 및 임상자료를 두군간에 비교하였다. 3) 결과: 금번 연구에서 2,041명이 질병군(47.6%), 2,243명이 정상군(52.4%)이며 총 테스토스테론과 나이(r=0.032, P=0.034), HDL(r=0.133, P<0.001) 은 각각 양의 상관관계를 보이며, BMI(r=-0.198, P<0.001), 복부둘레(r=-0.184, P<0.001), 혈압, ALT(r=-0.132, P<0.001), 공복혈당(r=-0.105, P<0.001), TG(r=-0.119, P<0.001) 및 알부민(r=-0.108, P<0.001)은 각각 총 테스토스테론과 음의 상관관계를 보였다. 총 테스토스테론은 나이에 따라 증가하지 않았으며, 대사증후군, 고혈압, 및 당뇨병이 있는 사람들은 정상군에 비해 총 테스토스테론이 낮았다. 질병군이 남성갱년기에 이환될 확률이 정상군이 남성갱년기에 이환될 확률보다 1.595(95%CI, 1.355-1.876)배 높았다. 4) 결론: 정상군에서보다 질병군에서 총테스토스테론이 낮았다. 총테스토스테론은 나이가 아니라 질병에 의해 영향을 받는다.

▼ This thesis investigates the age - related decline in the various available measures and estimates of serum testosterone levels in men. Testosterone circulates predominantly bound with high affinity to sex - hormone binging globulin ( SHBG ) in plasma ( ~ 60 % ) and with lower affinity to albumin ( < 40 % ) ; approximately 1 - 2 % circulates unbound in plasma. It is the albumin - bound and free fractions ( termed " bioavailable testosterone " ) that are most likely to have biological effects on target tissues. This thesis reports the establishment, validation and derivation of normal ranges for an ammonium sulphate precipitation method for the measurement of bioavailable testosterone in serum. This method is in use by a number of laboratories at present including the laboratory of Professor John Morley at St Louis University with whom we collaborated. Testosterone has been shown, both cross - sectionally and longitudinally, to decline progressively beginning around the age of thirty. Total testosterone declines at approximately 0.4 % per year while bioavailable and free testosterone decline at approximately 1.2 % per year. The mechanisms that may be responsible for this include age - related changes to the hypothalamic - pituitary - testicular axis, increased SHBG levels, environmental factors, medication and chronic illness. This decline may contribute to a multitude of physiological, psychosexual and cognitive changes associated with ageing in men. This thesis crosssectionally examines the possible determinants of the various fractions of serum testosterone and the associations with various physical, psychosexual and lifestyle variables and with chronic disease and medication use. These cross - sectional data were generated from the Florey Adelaide Male Ageing study, which randomly recruited 568 men from the north and west suburbs of Adelaide, between August 2001 and August 2002. Moreover, this thesis includes a randomised controlled trial of testosterone replacement therapy in men aged 60 years and over with low - normal testosterone levels at baseline, recruited by newspaper advertisement. The goals of testosterone replacement therapy might be to prevent osteoporosis, age related frailty and falls, and to maintain optimal physical, sexual, emotional and cognitive health during the ageing process. This intervention study focused on the effect of treatment on body composition and muscle strength, symptoms of testosterone deficiency, visuospatial cognition, mood, wellbeing and quality of life. Finally, preliminary work was initiated to develop an in vitro bioassay for the measurement of serum testosterone bio - action. This was done using a transient transfection protocol in cultured cells, where androgen receptor and androgen response elements were introduced into the cells, subsequently treated with testosterone containing media and the amplitude of response quantified using a dual - luciferasereporter assay. In summary, this thesis discusses the issues with the measurement of testosterone in plasma and… Advisors/Committee Members: Wittert, Gary Allen (advisor), Medical School (school).

▼ Aromatase, a member of the cytochrome P450 superfamily, catalyses the conversion of androgens to estrogens; specifically, testosterone to estradiol and androstenedione to estrone. Aromatase is widely expressed across a range of tissues and deleterious metabolic effects are observed in both murine aromatase knock-out models and in rare human cases of aromatase deficiency. The effects of pharmacological inhibition of aromatase, as employed in the treatment of breast cancer, are not well characterised. This thesis addresses the hypothesis that aromatase inhibition, and consequent changes in sex steroid hormone action (higher androgen:estrogen ratio), results in disadvantageous changes in body composition and reduced insulin sensitivity. In a cohort study of 197 community-dwelling men, lower testosterone and SHBG concentrations were observed in those fulfilling criteria for metabolic syndrome, although no relationship with estrogens was observed. The strongest determinant of circulating estrogens was substrate androgen concentration. A case-control study of aromatase inhibitor treated breast cancer patients and age-matched controls (n=40) demonstrated decreased insulin sensitivity and increased body fat in those treated with aromatase inhibitors; serum leptin concentration and leptin mRNA transcript levels (in subcutaneous adipose tissue) were elevated in this group. In healthy male volunteers (n=17), 6 weeks of aromatase inhibition (1 mg anastrozole daily) resulted in reduced glucose disposal during a hyperinsulinaemic euglycaemic clamp study, with d2-glucose and d5-glycerol tracers. No effects upon hepatic insulin sensitivity, lipolysis or body composition were noted, although serum leptin concentration was reduced following aromatase inhibitor administration. In conclusion, aromatase inhibition is associated with increased insulin resistance and, in women, increased body fat. This may be relevant for patients receiving aromatase inhibitor therapy, where more careful monitoring of glucose tolerance may be warranted.

▼ The adipocyte-derived hormone leptin plays a key role in regulating energy homeostasis and reproduction in adults. A compelling body of evidence indicates that the efficacy of leptin to suppress food intake and increase energy expenditure is dependent on the neuroarchitecture of the feeding circuitry programmed by leptin during development. This neurotrophic action of leptin shares many aspects of developmental functions of sex steroid hormones. Moreover, overlapping central targets of these two hormones raises the possibility that leptin and sex steroids may interact to direct key neurodevelopmental events. The ventral premammillary nucleus (PMv) contains a high density of neurons expressing leptin receptors (LRb) and androgen receptors (AR), making the PMv an excellent model system to study the developmental effect of the interactions between these two hormones. To this end, this thesis focuses on examining how developmental interactions between leptin and testosterone specify the development of PMv connectivity and the mechanisms underlying this interaction. ❧ In the first half of this thesis we characterize the ontogeny of PMv projections and determine how leptin or testosterone specifies PMv connectivity in male and female mice. Using both in vivo loss-of-function and in vitro gain-of-function assays, in conjunction with immunohistological staining, in a leptin deficient mouse model, we show that the PMv connectivity is sexually dimorphic due to a testosterone-dependent trophic action of leptin. ❧ In the second half of the thesis we investigate the cellular mechanisms that underlie the neurodevelopmental effects of leptin and testosterone. Taking advantage of transgenic mouse models lacking AR or impaired in specific LRb signaling, we show that the testosterone-dependent trophic action of leptin is mediated through AR. In addition, our data demonstrate that during development LRb and AR signaling converges on the ERK pathway and to a lesser extent, on the STAT3 pathway, to synergistically promote neurite outgrowth from PMv neurons. In adults, AR signaling potentiates STAT3 activation in PMv neurons in response to leptin injection, which corresponds to a greater sensitivity to leptin-induced bodyweight loss in adult male mice. ❧ In summary, we demonstrate that metabolic hormone leptin can affect the wiring of reproductive circuitry in a sexually dimorphic manner. This dissertation highlights the biological importance of hormonal interactions during brain development and provides insight into the mechanisms responsible for sex linked aberrations in neural connectivity that contributes a variety of hormone-sensitive neurological disorders.

▼ The steroid hormones testosterone and cortisol can be considered hormones for environmental challenges; they are involved in adaptive neural and behavioral responses towards emotional stimuli. A key challenge of human psychoneuroendocrinology is to unravel the neural mechanisms by which testosterone and cortisol act on the brain to give rise to their effects on socio-emotional behaviors. Therefore, one of the main goals of the research reported in this thesis is to investigate neural mechanisms underlying the effects of cortisol on fear, reward and parenting behaviors. Another important challenge for human psychoneuroendocrinology is to investigate if the effects of hormones extend to behaviors that can be considered uniquely human. Hence, a second main goal is to investigate if testosterone influences higher order social functions, such as social cooperation and morality. Finally, hormones do not work in isolation: they interact with early life factors such as the prenatal hormonal milieu and early life stress such as childhood trauma. Another goal of this thesis is therefore to gather more insights in how theses early life factors interact with the effects of steroid hormones. To these ends, this thesis includes a literature review and empirical studies employing single administration of cortisol and testosterone together with neuroimaging and behavioral paradigms. A marker of prenatal testosterone is used in the testosterone studies, based on animal studies showing that prenatal testosterone programs the effects of the hormone in adult life. Childhood trauma is taken into account in the cortisol studies, as previous animal and human studies have demonstrated that this is an important factor in shaping the cortisol system. This thesis starts with a literature review that discusses evidence for the notion that testosterone and cortisol, together with serotonin, regulates reactive aggression. The evidence suggests that high testosterone and low cortisol levels together increases the occurrence of social aggression, and that low serotonin on top of this imbalance might specifically predispose towards impulsive aggression instead of instrumental aggression. This literature overview proposes this hypothesis as a guide for future research and provided the theoretical framework for the following studies. The findings of the first empirical part of this thesis show that cortisol modulates the brain systems important for reward, fear and parenting. It is also observed that early life factors such as childhood trauma shape the effects of cortisol on neural processing of stimuli important for parenting. The findings of the second empirical part of this thesis show that testosterone, in addition to affecting basal emotional processes such as fear and reward processing, also affects higher order social functions such as social cooperation and moral judgement. By using a proxy for prenatal testosterone exposure, it is shown that the effects of… Advisors/Committee Members: Honk, E.J. van, Terburg, D., Bos, P.A..

▼ Background: Studies showing a high prevalence of low serum testosterone in men with type 2 diabetes mellitus (T2DM) are well documented but evidence from sub-Saharan Africa is scanty. Aim: To determine the prevalence and associated risk factors of low serum testosterone and the prevalence of androgen deficiency symptoms in South African men with T2DM. Methods: A cross-sectional observational study was performed among men with T2DM attending two outpatient adult diabetes clinics in KwaZulu-Natal. Androgen deficiency symptoms were assessed using the Ageing Male’s Symptom Scale (AMS) questionnaire and direct enquiry. Serum total testosterone (TT), sex-hormone binding globulin (SHBG), luteinising hormone (LH), HbA1c, fructosamine, serum lipids were measured and free-testosterone (FT) was calculated. TT, SHBG and FT levels were measured in control subjects with no history of diabetes. Results: The study included 148 men with T2DM (Study Group) and 50 control subjects (Control Group). The mean age of the control group was 43.9 ± 10.7 years and the mean BMI was 27.11 ± 4.2 kg/m2. In the study group, the majority were African (Black) (58.7%); Indians (39.2%) and Whites (2.1%) constituted the remainder. Mean age was 57.5 ± 11.2 years; mean duration of diabetes 11.4 ± 8.9 years; mean HbA1c was 8.6 ± 1.9%. Metabolic syndrome was found in 86.4% (n:127) of the Study group. Mean TT, SHBG, FT and median LH (IQR) in the Study group were within normal range (14.5 ± 5.8 nmol/l, 40.7 ± 20.3 nmol/l, 265.9 ± 90.4 pmol/l and 5.3 [3.8-7.3] IU/l, respectively). However, mean serum TT and FT was lower in the Study group than Control subjects (14.5 ± 5.8 vs. 18.8 ± 7.2 nmol/l, p <0.001 and 265.9 ± 90.4 vs. 351.7 ± 127.3 pmol/l, p<0.001). The prevalence of LSTT and LSFT was 35.8% and 16.2%, respectively. Prevalence of LSFT increased with age and higher body mass index (BMI) categories with the highest rate noted in >40 kg/m2 BMI category (50%). In multivariate analysis, LSFT was significantly associated with age [OR 1.05 (95% CI 1.02-1.218), p=0.043] and waist circumference (WC) [OR 1.033 (95% CI 0.999- 1.068), p=0.059]. LSTT was associated with BMI only [OR 1.138 (95%CI 1.063- 1.218), p<0.0001]. TT correlated inversely with BMI, WC and the number of metabolic syndrome criteria. FT correlated inversely with BMI, WC and WHR. For both FT and TT, no significant correlation was observed with HbA1c. The prevalence of androgen deficiency symptoms using AMS score was 74.5%. The prevalence of any androgen deficiency symptom on direct enquiry was 68.9%. The AMS score correlated poorly with LSTT or LSFT and was not superior to direct enquiry. Conclusion: In this group of predominantly African and Indian men with T2DM from KwaZulu-Natal, there was a high prevalence of LSTT and LSFT. Serum TT and FT was lower in men with T2DM compared to control subjects. Waist circumference was a significant risk factor associated with LSFT while LSTT was associated with higher BMI and older age. There was a high prevalence of androgen deficiency symptoms using… Advisors/Committee Members: Motala, Ayesha Ahmed. (advisor), Pirie, Fraser James. (advisor).

Thesis Ph. D. Michigan State University. Psychology 2013.

Maturation of social cognition and a gain in social proficiency are universal aspects of adolescent development that prepare an individual for adulthood. Social cognition involves the perception and interpretation of social cues, followed by the generation of a behavioral response. Social proficiency is acquired through the ability to make behavioral adaptations as one learns from social experience. The pubertal rise in testosterone secretion results in both activation and organization of the neural circuits underlying adult male social behaviors, including sexual behavior, which may contribute to the developmental changes in social cognition and gain in sexual proficiency. To assess the contribution of pubertal testosterone to the maturation of adult social behavior, we utilize the [email protected]/[email protected] experimental animal model. In this model, male Syrian hamsters are deprived of testosterone during puberty (defined as [email protected]) or for an equivalent amount of time during adulthood (defined as [email protected]) and then given testosterone replacement in adulthood for two weeks before behavior testing. If [email protected] and [email protected] males differ in behavior, we infer that the difference is due to organizational effects of pubertal testosterone. If [email protected] and [email protected] males show similar behavior, then we infer that the adolescent maturation of that behavior is due to hormone-independent or activational actions. We first tested the hypothesis that the adolescent acquisition of social reward does not depend on organizational effects of pubertal testosterone. We found that both [email protected] and [email protected] males show a CPP for vaginal secretions and a receptive female, indicating that the adolescent maturation of social reward is independent of pubertal testosterone. Second, we tested the hypothesis the adolescent gain in sexual proficiency does depend on organizational effects of testosterone. When sexual experience is equated for both [email protected] and [email protected] males, [email protected] males do not inhibit maladaptive behaviors with sexual experience, whereas [email protected] males do. These data suggest that testosterone during puberty programs the ability to adapt behaviors (via inhibition) in a social context-dependent manner. Third, we tested whether pubertal testosterone organizes the adolescent gain in sexual proficiency through the regulation of the transcription factor ΔFosB in the infralimbic medial prefrontal cortex (IL). We found that ∆FosB was induced in the IL after sexual experience in [email protected], but not [email protected], males. Furthermore, over-expression of ∆FosB in the IL of [email protected] males prior to sexual behavior testing was sufficient to reverse the deficits in behavioral inhibition found in [email protected] males. Taken together, these data provide evidence that social reward develops independently of pubertal testosterone, whereas the ability to inhibit inappropriate behavior is organized by pubertal testosterone through the regulation of ∆FosB in the IL.

Dissertação de Mestrado apresentada ao ISPA - Instituto Universitário

Tem sido proposto na literatura que, em humanos, a resposta da testosterona à competição possa ser modulada por variáveis cognitivas. Neste estudo, testamos a hipótese de que as variações dos níveis de testosterona, verificadas após uma competição, não estejam tão relacionadas com o resultado em si mas antes com a forma como o sujeito avalia o evento em questão, em particular com as suas expectativas acerca da competição. Para isso, foram manipuladas as expectativas que um grupo de participantes, do sexo feminino, criou acerca de uma competição e do seu resultado. Foi construída uma tarefa, em contexto laboratorial, que nos possibilitou a manipulação das suas expectativas. Assim, as participantes foram distribuídas por dois grupos artificiais e foi-lhes fornecido um falso feedback, que lhes direcionava as expectativas. Desta forma, os dados recolhidos apresentam informação acerca de participantes que perderam ou ganharam, em situações de confirmação de expectativas ou de violação de expectativas. Posto isto, colocou-se a hipótese de que se obteria maior resposta de testosterona nas participantes vencedoras, comparativamente com as derrotadas, de acordo com o modelo biossocial e avançou-se com a possibilidade de uma maior amplificação desta resposta de testosterona, quando as expectativas eram violadas. De facto, a última predição, confirmou-se, houve uma diferença significativa na variação de T, entre vencedoras e derrotadas, apenas nas sessões em que as expectativas das participantes foram violadas. Contudo, ao contrário do esperado, encontrou-se evidência de um resultado inverso ao modelo biossocial, as participantes que venceram a competição apresentaram valores inferiores de T.

It has been proposed in the literature that, in humans, the response of testosterone to the competition can be modulated by cognitive variables. In this study, we tested the hypothesis that variations in testosterone levels observed after a competition are not so related to its outcome in itself but rather with the way the subject evaluates the event in question, particularly with expectations about the competition. To study this, we manipulated the expectations that a group of female participants, created about the competition and its result. We developed a task in laboratory context, which enabled us the manipulation of their expectations. Thus, the participants were distributed into two artificial groups and were instructed with a false feedback that shifted the expectations. In this way, the data collected feature information about participants that have lost or won, in situations of confirmation of expectations or violation of expectations. Therefore, we placed the hypothesis that the testosterone response would be more expressive in participants that won compared with the defeated participants, according to the biosocial model, and we expected a greater amplification of this response when expectations were violated. In fact, the last prediction was confirmed,…

▼ The HVC of the adult songbird forebrain undergoes gonadal steroid-mediated survival of new neurons throughout life. Angiogenesis and neuronal recruitment are serially and causally linked in this process, such that testosterone-induced angiogenesis is necessary for neuronal recruitment. To better understand the contribution of testosterone-induced transcriptional programs to this adult neuronal recruitment, we assessed the effects of androgen exposure on gene expression in the adult canary HVC. We first generated and sequenced a library of cDNAs derived from testosterone-treated adult female and male canary HVCs. We then used these sequences to establish two microarray platforms – a spotted cDNA array and a high-density oligonucleotide microarray. Using the higher quality high-density oligonucleotide array, we profiled the mRNAs of laser capture microdissected HVC sections, derived from testosterone-treated female canaries killed at varying time-points after androgen treatment. This analysis revealed >1000 probe sets that were regulated by testosterone; gene ontology analysis indicated strong differential regulation of genes associated with neuronal survival, while pathway analysis revealed strong differential expression of genes involved in nitric oxide signaling. In situ hybridization (ISH) confirmed that NRGN, RGS4, PPP3CA and CAMK2B mRNA were highly differentially expressed in HVC, whereas PLCB1 mRNA was diminished. Real-time quantitative PCR analysis confirmed that testosterone induced HVC RGS4 mRNA expression, but suppressed HVC NRGN, calcineurin/PPP3CA and CAMK2B. This pattern of regulation suggests that the nitric oxide regulatory pathways are critically involved in the androgenic modulation of cellular plasticity in the adult HVC, since this set of transcripts is highly associated with NO synthesis and signaling. In addition, we noted that the angiogenic modulators CRHBP and ADD3 were selectively enriched in the HVC; ISH then revealed that CRHBP mRNA expression was stimulated by testosterone specifically in HVC interneurons, while RGS4 was expressed in a complementary fashion in HVC excitatory projection neurons. Together, our transcriptional data suggest that HVC interneurons may subserve a regulatory role in testosterone-dependent angiogenesis, which may in turn govern HVC neuronal recruitment through NO-modulatory pathways.

O objetivo da presente dissertação foi investigar o efeito da territorialidade e do nível do adversário nas respostas hormonais e comportamentais de jogadores de basquetebol. Para tanto, foram realizados dois estudos. No primeiro, investigou-se o efeito da territorialidade nas respostas hormonais e comportamentais decorrentes de jogos oficiais de basquetebol. Dezoito jogadores, do sexo masculino, de duas equipes da categoria sub-19 (ranqueadas em primeiro e segundo lugar na competição) foram avaliados. As equipes jogaram entre si e, portanto, cada equipe realizou um jogo ëm casaë um jogo \"fora de casa\". Amostras de saliva foram coletadas antes e após as duas partidas, para análise dos hormônios testosterona (T) e cortisol (C). Antes do aquecimento, os atletas responderam um questionário de ansiedade pré-competitiva, (Competitive State Anxiety Inventory-2; CSAI-2), e 30 minutos após a partida, classificaram a magnitude do esforço através do método da percepção subjetiva de esforço da sessão (PSE da sessão). A concentração de T PRÉ-jogo foi maior na condição \"casa(̈versus \"fora de casa\"); verificou-se um aumento da concentração de T e C do momento PRÉ- para o PÓS-jogo, independentemente do local do jogo; correlações significantes foram apresentadas entre as respostas hormonais e comportamentais. Esses resultados sugerem a ocorrência do fenômeno da territorialidade, e confirmam que a competição é um evento estressor capaz de alterar a concentração hormonal. No segundo estudo, a influência do nível do adversário nas respostas hormonais e comportamentais de jogadores de basquetebol foi investigada. Dez atletas de uma equipe sub-19 foram avaliados em três jogos oficiais distintos e em uma sessão de treinamento (ST). Em cada um dos jogos oficiais, a equipe enfrentou adversários de diferentes níveis de qualificação, a saber: jogo fácil (JF), jogo médio (JM) e jogo difícil (JD). A classificação do nível do adversário foi realizada por um membro da comissão técnica no início da temporada e monitorada de acordo com a posição de cada uma das equipes durante o campeonato. Foram realizadas coletas de saliva antes e após as quatro condições (três jogos e uma sessão de treinamento) para análise da concentração de T e C. Antes do aquecimento, em todas as condições, os jogadores responderam o questionário CSAI-2 e, aproximadamente 30 minutos após o jogo, responderam a PSE da sessão. A concentração de T aumentou de PRÉ para PÓS no ST e JD; a concentração de T PRÉ-JD foi maior em relação a situação PRÉ-ST. A concentração de C aumentou de PRÉ para PÓS em ST, JM e JD, e a concentração C PRÉ- e PÓS-JD foi maior quando comparada aos mesmos momentos na ST. As ansiedades somática e cognitiva se mostraram maiores no JM e JD em relação ao JF. A autoconfiança foi maior na ST quando comparado com o JM e JD. A PSE da sessão foi maior nos JM e JD em relação à ST. Os resultados do presente estudo indicam que jogos oficiais contra adversários de diferentes níveis podem promover diferentes respostas hormonais e perceptuais

▼ Abstract: Purpose: to evaluate the relative efficiency of leuprolide 3.75 mg, leuprolide 7.5 mg, and goserelin 3.6 mg in relation to the reduction of serum testosterone, regarding the levels of castration. Methods: we evaluated prospectively 60 randomized patients with advanced prostate carcinoma, with indication for hormone blockade. The patients were divided into 3 groups of 20: Group 1) received leuprolide 3.75 mg; Group 2) received leuprolide 7.5 mg; group 3) received goserelin 3.6 mg. All groups were treated with monthly application of the respective drugs. Results: the patients' ages were similar within the three groups, with a median of 72, 70, and 70 in groups 1, 2, and 3, respectively. Of the patients that received leuprolide 3.75 mg, leuprolide 7.5 mg, and goserelin 3.6 mg, 26.3%, 25%, and 35%, respectively, did not reach castration levels, considering a testosterone cut of ?50 ng/dl. 68.4%, 30%, and 45%, respectively, did not reach castration levels, considering a testosterone cut of ?20 ng/dl. Conclusions: There were no statiscally significant differences in the levels of castration when comparing with leuprolide 3.75 mg, leuprolide 7.5 mg, and goserelin 3.6 mg, when comparing the three substances altogether. When compared in groups of two, there was a statiscally significant difference between leuprolide 3.75 mg and leuprolide 7.5 mg, in which the latter presented better results in reaching castration levels, when considered equal or less than 20ng/dl. The importance of this difference, however, must be measured with caution, since the comparison of the three groups simultaneously did not reach the established significance level, even though it came close Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Matheus, Wagner Eduardo (advisor), Ferreira, Ubirajara, 1956- (coadvisor), Universidade Estadual de Campinas.

Resistance exercise training (RET) can lead to muscle hypertrophy; however, the relative contribution that exogenous (protein supplementation and specific training variables) versus endogenous (biology inherent to the individual) factors have on RET-induced muscle hypertrophy is controversial. In Study 1, we provided an evidence-based conclusion that protein supplementation during periods of RET results in a small but statistically significant increase in RET-induced muscle hypertrophy. In Study 2, we corroborate previous research and observed that the amount of mass lifted per repetition (load) did not determine RET-induced muscle hypertrophy in resistance-trained men when RET was performed to volitional fatigue. In Study 4, we observed similar muscle fibre activation following resistance exercise with lighter versus heavier loads when both were lifted until volitional fatigue. In Studies 2 and 3, we observed no relationship between circulating anabolic hormones (e.g., testosterone) and RET-induced muscle hypertrophy. Nonetheless, in Study 3, we found significantly greater muscle androgen receptor content in the top versus the bottom quintile of respondents for muscle hypertrophy following 12 weeks of RET indicating that androgen receptor content, and not circulating androgen concentration, may be an important determinant of hypertrophy. Finally, in Study 5, we observed that RET-induced muscle hypertrophy was an consistent within an individual (independent of load and limb) but considerably different between participants. Together, these data suggest that the exogenous factors we studied – protein supplementation and load (when RET was performed to volitional fatigue) – had a relatively small influence on RET-induced muscle hypertrophy. In contrast, we found that endogenous variables, such as intramuscular androgen receptor content and likely other genetic influences, appear to contribute more to the significant heterogeneity seen in RET-induced muscle hypertrophy. Future research in this area should prioritize understanding the biology that underpins the individual variability in RET-induced muscle hypertrophy.

Thesis

Doctor of Philosophy (PhD)

Resistance exercise training (RET) increases muscle size (hypertrophy); however, the relative influence that protein supplementation, specific training variables, and individual (genetic) variation have on the RET-induced hypertrophy is controversial and largely unknown. Broadly, data in this thesis show that protein supplementation slightly augments RET-induced hypertrophy, and that the magnitude of RET-induced hypertrophy may be related to the number of androgen (e.g., testosterone) receptors inside an individual’s muscle. In contrast, we found that neither load nor hormones affect RET-induced hypertrophy. Interestingly, data in this thesis also show that RET-induced hypertrophy is consistent within an individual but varies considerably between people, which illustrates the greater influence that individual variation has on RET-induced hypertrophy. We conclude…

▼ The ability to characterize and enhance market traits in livestock has facilitated a greater interest in determining the genetic tool kit available for manipulation. In swine, using new approaches in genomics, such as microarray analysis and biological pathway analysis, we can show genes up and down regulated in a variety of processes and conditions. To this end, we identify the genes, pathways, and disease biomarkers affected by divergent selection of testosterone in boars. Testicular samples were taken from boars at 0, 30, 120, 150, and 180 days of age for lines of high (HT) and low testosterone (LT). Evidence that many of the differences in gene expression were at the pubertal period of 150 days led to a subsequent microarray study of the 150 day HT and LT animals. Microarray studies were followed by validation with real-time RT-PCR of 11 genes and extensive GeneGo pathway analysis (Metacore) of differentially expressed genes. While increased testosterone has long been associated with increased growth rates, we now have supporting genomic evidence of the genes and pathways up-regulated and down-regulated in these lines. To this end, this study has identified several disease biomarkers that may require further investigation and biological pathways associated with growth and metabolism that allow the recommendation of selective breeding for high testosterone to increase lean growth traits. The genetic blueprint contained in the spermatozoan transcriptome can also illuminate key issues in swine reproduction. By developing a procedure for effective RNA extraction of boar spermatozoa we are one step closer to elucidating the porcine sperm transcriptome and the genes implicated in growth and fertility. A viable protocol was developed to handle the complexities of large scale extraction of RNA from porcine semen utilizing an RNA carrier and Dnase treatment. This protocol was validated with PCR amplification of Sus scrofa prm1 in order to provide evidence of a successful RNA extraction from sperm. Advisors/Committee Members: Melissa S.
