BACKGROUND: Polycystic ovarian syndrome (PCOS) and hypovitaminosis D are the two most common endocrine disorders in young women leading to many adverse metabolic consequences. We evaluated the correlation of 25-hydroxy Vitamin D (25OHD) with metabolic parameters and insulin resistance in PCOS. MATERIALS AND METHODS: We included 100 PCOS patients (age 18-40 years, duration >6 months) serially, in this cross-sectional study. We excluded patients with past use of insulin sensitizers and hormone therapy...

INTRODUCTION: Kallmann syndrome (KS) is a rare, congenital disorder combining hypogonadotropic hypogonadism (HH) due to GnRH-deficiency with anosmia. Traditionally thought to require lifelong therapy it turns out to be a reversible condition in some patients. CASE REPORT: We present a case of a 22-year old man with absent puberty due to KS, in whom genetic testing revealed heterozygosity for a mutation in the PROK2 gene. Pubertal development and virilisation was achieved by using human chorionic gonadotropin (hCG) injections followed by testosterone replacement...

Androgens play a crucial role in bone, muscle and fat metabolism, erythropoiesis and cognitive health. In men aged 40-79 years the incidence of biochemical deficiency and symptomatic hypogonadism is 2.1-5.7%. Decreased libido or reduced frequency and quality of erections, fatigue, irritability, infertility or a diminished feeling of wellbeing may be presenting complaints. However, a significant proportion of men with androgen deficiency will be identified when they present for unrelated concerns. Important factors to elicit from the history in addition to the presenting complaint include: a medical history of obesity, type 2 diabetes, systemic diseases or metabolic syndrome which all impact on testosterone physiology...

The original prohibition of testosterone therapy for men with prostate cancer was based on outdated concepts developed more than 70 yr ago. Current evidence, although limited, provides consistently reassuring results that testosterone therapy may be reasonably offered to many men with prostate cancer. These men may experience valuable benefits in quality of life if they suffer from symptoms of testosterone deficiency (hypogonadism).

Despite the androgenic dependence, other hormones, growth factors, and cytokines are necessary to support prostatic growth and maintain the glandular structure; among them, prolactin is a non-steroidal hormone secreted mainly by the pituitary gland. However, extra-pituitary expression of prolactin, such as in the prostate, has also been demonstrated, highlighting the paracrine and autocrine actions of prolactin within the prostate. Here, we investigated whether prolactin modulation alters ventral prostate (VP) morphophysiology in adult castrated rats...

Testosterone deficiency has been correlated with increased cardiovascular diseases, which in turn has been associated with increased oxidative stress. Several studies have considered cholesterol oxidation products (COPs) as oxidative stress biomarkers, since some of them play pro-oxidant and pro-inflammatory roles. We have previously described the cardioprotective effects of a dosahexaenoic acid (DHA) supplemented diet on the aortic and mesenteric artery function of orchidectomized rats. The aim of this study was to investigate whether impaired gonadal function alters the formation of COPs, as well as the potential preventive role of a DHA-supplemented diet on that effect...

The relationship between testosterone deficiency (TD) syndrome and surgical resilience has a great impact in the modern approach to male elderly patients. There is good evidence that low levels of T are a strong marker for cardiovascular risk; also, TD is frequently associated with increased cardiovascular and all-cause mortality especially in cardiac older frail men. Screening for low T should be mandatory in high risk groups candidate to surgery including those with diabetes, metabolic syndrome and obesity, even though benefits from T-treatment on survival rates are unclear...

Testosterone deficiency is a prevalent condition in male patients with chronic kidney disease. However, it is not known whether the type of renal replacement therapy has an impact on testosterone deficiency that accompanies loss of renal function. METHODS: The cross-sectional study enrolled 79 prevalent male patients on dialysis; 43 on haemodialysis (HD) and 36 on peritoneal dialysis (PD). The median age was 69 years and 31.6% were diabetics. Endogenous testosterone levels were measured by immunoluminescence assay (normal range 3-10...

BACKGROUND: Olfactory disorder is an early manifestation of Parkinson's disease (PD), likely to be associated with abnormalities of the dopaminergic neurons in the olfactory bulb (OB); however, the causes of olfactory disorder in PD are not entirely clear. Some studies showed that melatonin (MT) and androgens (mainly testosterone, T) might participate in the pathogenesis of PD. The research aimed to investigate effects of MT or T deficiency on OB dopaminergic neurons in rats. METHODS: One hundred and twenty normal male Wistar rats were randomly divided into the control, sham operation pinealectomy (PX), sham operation gonadectomy (GDX), PX, GDX, and PX + GDX groups...

We previously showed that testosterone (T) deficiency enhanced high-fat diet (HFD) induced hepatic steatosis in rats that was independent of insulin resistance, and that T replacement reduced hepatic macrovesicular fat accumulation and inflammation. The present report explores the mechanism of T-protective effects on HFD-induced steatohepatitis. Adult male rats were randomized into four treatment groups for 15 weeks (intact rats on regular chow diet or HFD, and castrated rats on HFD with/without T replacement)...

Hypogonadotropic hypogonadism (HH) is common and occurs prematurely in HIV-infected men. However, HH with very low testosterone has not been described. Three men with normal pubertal development and HIV1 diagnosis at the ages of 22, 34 and 35 years. All complained of decreased libido, anejaculation and erectile dysfunction thirteen years, six months and one year after HIV diagnosis, respectively. Two had depressive syndrome and two were treated with antiretroviral therapy. Laboratory tests revealed isolated HH in all...

In daily practice, clinicians are often confronted with obese type 2 diabetes mellitus (T2DM) patients for whom the treatment plan fails and who show an inadequate glycemic control and/or no sustainable weight loss. Untreated hypogonadism can be the reason for such treatment failure. This case describes the profound impact testosterone therapy can have on a male hypogonadal patient with metabolic syndrome, resulting in a substantial and sustained loss of body weight, pronounced improvement of all critical laboratory values and finally complete remission of diabetes...

Semen cuscutae is a well-known Chinese medicine which has been used to nourish kidney. It is the first study to demonstrate that the polysaccharides from semen cuscutae showed significant activity of nourishing kidney-yang by increasing the levels of testosterone and estradiol, decreasing the level of blood urea nitrogen, improving immune function, possessing antioxidant effect. Three homogeneous polysaccharides were obtained by DEAE-cellulose and Sephacryl S-400 which were named as C-7WR1, C-7WR2 and C-7WR3 with average molecular weight of 7...

Cognitive function and testosterone level of men decline concurrently with aging. Low testosterone levels are associated with higher risk of Alzheimer's disease and mild cognitive impairment in men. There are continuous debates on whether this relationship is casual or causal. This paper aims to summarize the current evidence on the association between testosterone level and cognitive function in elderly men. The presence of testosterone, androgen receptor and its responsive genes hint that testosterone has biological functions in the central nervous system...

Prostatic complications are common in patients with diabetes. This study investigated the effect of different ginger ingredients: zingerone, geraniol, and 6-gingerol on the prostate in diabetic rats. Diabetes was induced in Wistar rats by streptozotocin intraperitoneal injection (50 mg/kg), and the rats were left for 10 weeks to develop prostatic complications. In diabetic treated groups, rats received daily oral zingerone, geraniol, and 6-gingerol in doses of 20, 200, and 75 mg/kg, respectively, in the last 8 weeks...

BACKGROUND: Adrenocortical carcinoma (ACC) is a rare malignancy, with an annual incidence of 1 or 2 cases per million. Biochemical diagnosis is challenging because up to two-thirds of the carcinomas are biochemically silent, resulting from de facto enzyme deficiencies in steroid hormone biosynthesis. Urine steroid profiling by GC-MS is an effective diagnostic test for ACC because of its capacity to detect and quantify the increased metabolites of steroid pathway synthetic intermediates...

Klinefelter syndrome (KS) is a chromosomal disorder affecting males, with the typical karyotype of 47,XXY due to a supernumerary X chromosome, which causes progressive testicular failure resulting in androgen deficiency and infertility. Despite it being the most common sex chromosomal disorder, its diagnosis is easily missed. In addition to its classical clinical features of tall stature, gynaecomastia, small testes, and symptoms and signs of hypogonadism including infertility, KS is also often associated with neurocognitive, behavioural and psychiatric disorders...

The male hormone testosterone exerts different effects on glucose and energy homeostasis in males and females. Testosterone deficiency predisposes males to visceral obesity, insulin resistance and type 2 diabetes. However, testosterone excess predisposes females to similar metabolic dysfunction. Here, we review the effects of testosterone actions in the central nervous system on metabolic function in males and females. In particular, we highlight changes within the hypothalamus that control glucose and energy homeostasis...
