Attainment of puberty in animals is dependent on their age, body weight, nutritional status, genetic and environmental conditions. Nutritionally, organic minerals are suggested to improve semen production, sperm motility and male fertility. In this context, role of organic zinc (Zn) and copper (Cu) in advancing male puberty and semen characters in Osmanabadi goats were studied. Forty one (n = 41) bucks (Aged 5 months) were divided into ten groups and the dietary treatments comprised of a control group (basal diet; without additional trace mineral supplementation) and nine treatment groups that received, in addition to the basal diet, various doses of trace minerals (mg) on per kg dry matter basis, organic Zn as low Zn20, medium Zn40 and high Zn60, organic Cu as low Cu12...

STUDY QUESTION: What are the impacts of elevated testosterone (T) and an obesogenic western-style diet (WSD), either independently or together, on fertility and metabolic adaptations of pregnancy in primates? SUMMARY ANSWER: Testosterone increases the time to achieve pregnancy, while a WSD reduces overall fertility, and the combination of testosterone and WSD additionally impairs glucose tolerance and causes pregnancy loss. WHAT IS KNOWN ALREADY: Both hyperandrogenemia and obesity are hallmarks of polycystic ovary syndrome, which is a leading cause of infertility among women worldwide...

Daniel Mønsted Shabanzadeh
Gallstone disease is highly prevalent in Denmark and other countries of northern Europe, and cholecystectomy for the treatment of clinical gallstone disease is one the most frequently performed surgical procedures. Research efforts for the identification of mechanisms involved in gallstone formation have a long history and the most established include bile cholesterol saturation, gallbladder motor function, and the enterohepatic circulation of secondary bile salts produced by fecal microbiota. A small number of determinants that are believed to affect these mechanisms have been identified until now...

Bisphenol-A(BPA) is a member of alkylphenol family, and shows adverse effects including reduced fertility, reproductive tract abnormalities, metabolic disorder, cancer induction, neurotoxicity and immunotoxicity. In the present study, we conducted Hershberger assay to evaluate whether the two candidates to replace BPA have androgenic or antiandrogenic activity. The assay was carried out using immature castrated Sprague-Dawley male rats. After 7 days of the surgery, testosterone propionate (TP, 0.4 mg/kg/day) and test materials (low dose, 40 mg/kg/day; high dose, 400 mg/kg/day) were administered for 10 consecutive days by subcutaneous (s...

BACKGROUND: Sex steroids are essential for sexual maturation, linear growth and bone development. However, there is no consensus on the optimal timing, dosage and dosage interval of testosterone therapy to induce pubertal development and achieve a normal adult height and bone mass in children with hypogonadism. CASE PRESENTATION: A monozygotic monochorial male twin pair, of which one boy was diagnosed with anorchia at birth due to testicular regression syndrome was followed from the age of 3 until the age of 18 years...

Low testosterone (T) in men, especially its free fraction, has been associated with loss of energy. In accordance, orchidectomy (ORX) in rodents results in decreased physical activity. Still, the mechanisms through which T stimulates activity remain mostly obscure. Here, we studied voluntary wheel running behavior in three different mouse models of androgen deficiency: ORX, androgen receptor (AR) knock-out (ARKO) and sex hormone binding globulin (SHBG)-transgenic mice, a novel mouse model of "low free T". Our results clearly show a fast and dramatic action of T stimulating wheel running, which is not explained by its action on muscle, as evidenced by neuromuscular studies and in a muscle-specific conditional ARKO mouse model...

AIMS: One third of males with type 2 diabetes have hypogonadism, characterized by low total and free testosterone concentrations. We hypothesized that this condition is associated with a compensatory increase in the expression of androgen receptors (AR) and that testosterone replacement reverses these changes. We also measured estrogen receptor and aromatase expression. MATERIALS AND METHODS: This is a randomized double-blind placebo controlled trial. 32 hypogonadal and 32 eugonadal men with type 2 diabetes were recruited...

BACKGROUND: Recent rapid advances in assisted reproductive health technologies enables couples with subfertility to conceive through various intervention. Majority of treatment modalities target the female partner. However it is important to identify and treat male factor subfertility right at the outset. We report a case of isolated follicle stimulating hormone deficiency resulting in azoospermia and primary subfertility. CASE PRESENTATION: A 28 year otherwise healthy male presented with primary subfertility with a healthy female counterpart...

PURPOSE: Fibrates are drugs widely used for the treatment of hyperlipidemic disorders. Previous studies on a novel analogue of clofibrate, called silafibrate, have shown good lipid lowering effects. This study was designed to assess the role of silafibrate as a peroxisome proliferator-activated receptors (PPARs) agonist on sperm health and spermatogenesis in adult male rats. MATERIAL AND METHODS: Seventy male Wistar rats were randomly allocated into 7 groups: Cl-10, Cl-20, and Cl-40 mg/kg/day (clofibrate); Si-10, Si-20, and Si-40 mg/kg/day (silafibrate); and C, control...

Exposure to mixtures of toxicants (e.g., pesticides) is common in real life and a subject of current concern. The present investigation was undertaken to assess some toxicological effects in male rats following exposure to methomyl (MET), abamectin (ABM), and their combination (MET+ABM), and to evaluate the ameliorative effect of zinc co-administration. Three groups of rats were designated for MET, ABM, and the mixture treatments. Three other groups were designated for zinc in conjunction with the pesticides...

With increasing knowledge that the immune system has a major impact on reproductive ‎health, the potential for cells arising in organs such as the thymus to alleviate oxidative stress ‎has been revealed. This study addresses the impact of neonatal thymectomy on male ‎reproductive function in pubertal and adult animals. Neonatal Sprague Dawley rats were allotted to four treatments consisting of fully thymectomized, partially thymectomized, intact, and sham-operated rats. Half of the rats in each treatment were sacrificed at 40 and the other half at 80 days of age...

Introduction: Gender dysphoria (GD) (DMS-5) is a condition marked by increasing psychological suffering that accompanies the incongruence between one's experienced or expressed gender and one's assigned gender. Manifestation of GD can be seen early on during childhood and adolescence. During this period, the development of undesirable sexual characteristics marks an acute suffering of being opposite to the sex of birth. Pubertal suppression with gonadotropin releasing hormone analogs (GnRHa) has been proposed for these individuals as a reversible treatment for postponing the pubertal development and attenuating psychological suffering...

Purpose: Transition from female to male gender after initiation of hormonal therapy involves both phenotypic and physiological changes. The response to treatment can vary widely from person to person. In this study, we looked at the response of the menstrual cycle after the initiation of testosterone therapy and we wished to determine the time period and dose of testosterone leading to the cessation of menses in transgender men. Methods: A retrospective chart review of 114 transgender men (individuals assigned female gender at birth but later identify themselves as males) seen for hormonal therapy in our transgender clinic from 2006 through 2016...

REVIEW
Justin B Smith, Jordan Rosen, Adam Colbert
INTRODUCTION: The symptoms of low testosterone frequently overlap with psychiatric complaints including depression and fatigue. Testosterone repletion has been shown to improve mood symptoms in men with low testosterone, although this finding has not been consistent across all studies. Despite the potential importance of low testosterone for psychiatry, the prevalence of low testosterone in men who present to psychiatric clinics with mental health complaints is unknown. AIM: To provide an overview of the current state of knowledge of the psychiatric complications of male hypogonadism, the challenges of screening for hypogonadism in a psychiatric population, and the potential mental health treatment implications of hypogonadism...

Alcohol use disorder (AUD) is a chronic, relapsing disease characterized by maladaptive patterns of alcohol drinking and seeking. Though sex differences exist in the etiology of AUD, much remains to be elucidated concerning the mechanisms underlying sex-related vulnerability to developing excessive alcohol-motivated behavior. While a large body of evidence points to an important role of circulating gonadal hormones in mediating cocaine reinforcement, findings are less consistent with respect to ethanol. Critically, the effects of gonadal hormones on the reinstatement of ethanol seeking, a model of "craving"-like behavior that reveals pronounced sex differences, has not yet been examined...
