Evidence from clinical observational studies and animal experiments suggests that hypogonadism is associated with the metabolic syndrome. In most of the experiments, androgen deficiency is induced by gonadectomy in the adulthood and relatively short-term effects of hypogonadism on metabolic parameters are usually observed. The purpose of this study was to evaluate the metabolic effects of long-term androgen deficiency starting before puberty in middle-aged male rats. The components of the metabolic syndrome were examined in male, female and gonadectomized male rats at the age of 18months...

Diabetes mellitus in human and animal models has been correlated with low sperm count, testicular abnormalities, high levels of germ cell death, and oxidative stress. In this study, we focus on three questions: (1) Is germ cell apoptosis stage-specific in diabetic male rats? (2) Could ascorbic acid (AA) reverse oxidative and histological damage and restore testicular dysfunction? (3) Could AA treatment restore fertility parameters in diabetic rats? Adult Sprague-Dawley rats were divided into four groups: control, diabetic, control plus AA, and diabetic plus AA...

We aimed to analyse the relationship between sperm parameters and International Index of Erectile Function (IIEF) score, the Female Sexual Function Index (FSFI) score, the testosterone (T) level in infertile men and between FSFI score and partners' fertility. Patients were divided into three groups; (group 1: azoospermia [n = 57], group 2: sperm count <15 million [n = 41], group 3: sperm count >15 million [n = 81]). Patients and their partners filled the IIEF and FSFI forms. The normality of the tests was analysed with Kolmogorov-Smirnov and Shapiro-Wilk tests...

Cross-sex hormone therapy (XHT) is widely used by transgender people to alter secondary sex characteristics to match their desired gender presentation. Here we investigate the long-term effects of XHT on bone health, using a murine model. Female mice underwent ovariectomy at either 6 or 10 weeks, and began weekly testosterone or vehicle injections. Dual-energy X-ray Absorptiometry (DXA) was performed to measure bone mineral density (BMD) and microCT was performed to compare femoral cortical and trabecular bone architecture...

Spontaneous reossification of the sellar floor after transsphenoidal surgery has been rarely reported. Strontium ranelate, a divalent strontium salt, has been shown to increase bone formation, increasing osteoblast activity. We describe an unusual case of a young patient with Cushing's disease who was treated with strontium ranelate for low bone mass who experienced spontaneous sellar reossification after transsphenoidal surgery. A 21-year-old male presented with Cushing's features. His past medical history included delayed puberty diagnosed at 16 years, treated with testosterone for 3 years without further work-up...

Testosterone is the main hormonal agent used for cross-sex hormone therapy in female-to-male transgender persons. Our aim was to systematically review the literature concerning the effects of testosterone on body mass index (BMI), blood pressure, hematocrit, hemoglobin, lipid profile, and liver enzymes in transgender men. PUBMED and EMBASE were searched for studies published until March 2017. Studies were included if they reported interventions with any dose of testosterone and comparison of variables before and during treatment...

Sarcopenia is defined as low muscle function (walking speed or grip strength) in the presence of low muscle mass. A simple screening test - the SARC-F - is available to identify persons with sarcopenia. The major endocrine causes of sarcopenia are diabetes mellitus and male hypogonadism. Other causes are decreased physical activity, loss of motor neuron units, weight loss, inflammatory cytokines, reduced blood flow to muscles, very low 25(OH) vitamin D levels and decreased growth hormone and IGF-1. Treatment for sarcopenia includes resistance and aerobic exercise, leucine enriched essential amino acids, and vitamin D...

BACKGROUND: Radiotherapy in patients with pelvis malignancy causes testes irradiation and resulted in testicular damages. Atorvastatin (ATV) in the low-dose is considered as antioxidant and anti-inflammatory properties. OBJECTIVE: This experimental study was investigated protective effects of ATV on irradiation-induced testicular injury. MATERIAL AND METHODS: Sixty male balb/c mice were randomly divided into 6 groups: 1: control, 2: irradiated (IR), 3, 4 and 5: IR plus ATV (10, 20 and 50mg/kg), 6: only ATV (50mg/kg)...

Phytosterols (PS) are plant origin sterols naturally found in many foods and added as food additives. Since 1950, PS have attracted considerable attention due to their ability to lower serum cholesterol and inhibit cardiovascular disease (CVD). However, recent studies have found that PS act as endocrine-disrupting chemicals in laboratory animals. Therefore, this study was aimed at finding the mechanism(s) for PS effects on the sexual behaviors and reproductive functions in male Japanese quails (Coturnix coturnix japonica)...

Background Dutasteride has been successfully used in treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). However, dutasteride inhibits 5α-reductase type 1 and type 2 enzymes and may compromises glucocorticoids and androgen metabolism and alters metabolic function resulting in undesirable metabolic and sexual adverse side effects. Aim The aim of this study was to investigate the long-term adverse effects of dutasteride therapy in men with BPH on: i) blood glucose, ii) glycated hemoglobin (HbA1c), iii) low density lipoprotein-cholesterol (LDL-C); high density lipoprotein-cholesterol (HDL-C) and total cholesterol (TC), iv) testosterone (T), v) liver alanine and aspartate aminotransferases (ALT and AST) and vi) erectile dysfunction (ED)...

Anti-Mullerian hormone (AMH), secreted by immature testicular Sertoli-cells, triggers the regression of male fetal Mullerian ducts. During puberty, AMH is downregulated by intratesticular testosterone. In females, AMH is secreted from granulosa cells of immature ovarian follicles from late prenatal life until menopause; serum concentration is 5-20 times lower in females than in males through lifetime. In boys, AMH determination is useful in the clinical setting as a marker of Sertoli cell function. Serum AMH is low in infants with hypogonadotrophic hypogonadism (and increases with FSH treatment), in patients with primary hypogonadism from early postnatal life and in Klinefelter syndrome from midpuberty...

Cancer and its treatment can lead in men to testosterone deficiency, accompanied by somatic and mental symptoms. Germ cell tumours and their treatment may disturb the pituitary-gonadal axis, hence leading to significant clinical abnormalities. In some prostate cancer patients, castration, temporary or permanent, is a desired therapeutic condition. Yet, it is burdened with various side effects of complex intensity and significance. Last but not least, patients in the terminal stage of a malignancy present with low testosterone concentrations as a part of anorexia-cachexia syndrome...

BACKGROUND: Androgenetic alopecia, or male pattern hair loss, is a hair loss disorder mediated by dihydrotestosterone, the potent form of testosterone. Currently, minoxidil and finasteride are Food and Drug Administration (FDA)-approved, and HairMax LaserComb, which is FDA-cleared, are the only treatments recognized by the FDA as treatments of androgenetic alopecia. OBJECTIVE: This systematic review and meta-analysis assesses the efficacy of nonsurgical treatments of androgenetic alopecia in comparison to placebo for improving hair density, thickness, growth (defined by an increased anagen:telogen ratio), or subjective global assessments done by patients and investigators...

Isolated follicle stimulating hormone (FSH) deficiency due to mutations in FSHβ is an extremely rare autosomal recessive disease that has only been reported in ten patients to date. Symptoms of the disease include amenorrhoea and hypogonadism in women and azoospermia and normal testosterone levels in men. This study describes a Chinese male patient who presented with cryptorchidism and infertility. His serum hormonal profile revealed low FSH, elevated LH and normal testosterone levels. Sequence analysis identified a novel homozygous mutation in the FSHβ gene (c...

Obesity causes low-grade inflammation that is involved in male infertility. Interleukin 1 beta (IL1β) plays an important role in this process. A high-fat diet (HFD) is the most common cause of obesity. However, the effect of a HFD on IL1β and its consequence in reproduction remain unclear. We established a HFD model in mice treated at immature stage (mice-TIS) and mice treated at mature stage (mice-TMS). Surprisingly, we found that a HFD decreased IL1β levels and was accompanied by an increase in testosterone in mice-TIS, while the reverse results were observed in mice-TMS...

BACKGROUND: Obesity is associated with both impaired testosterone production and a chronic state of low grade inflammation. Previously it was believed that this inflammation was mediated by a decline in the immunosuppressive action of testosterone. However, more recently an alternative hypothesis (GELDING theory) has suggested that inflammation originating from the passage of intestinal bacteria into the circulation (metabolic endotoxaemia) may actually be the cause of impaired testicular function in obese men...
