Testosterone supplementation regimens are efficacious for improving both hypogonadal symptoms and serum total testosterone levels. Younger men appear to respond better to symptom improvement following testosterone therapy.

M en with obesity, the metabolic syndrome, and type 2 diabetes have low total and free testosterone and low sex hormone–binding globulin (SHBG). Conversely, the presence of low testosterone and/or SHBG predicts the development of metabolic syndrome and type 2 diabetes. Visceral adiposity present in men with low testosterone, the metabolic syndrome, and/or type 2 diabetes acts through proinflamm...

OBJECTIVE The purpose of the present study was to investigate the correlation between serum testosterone levels and bone mineral density (BMD) in postmenopausal women. MATERIALS AND METHODS The study group was made up of postmenopausal women admitted to our tertiary center. Serum calcium, phosphorus, albumin, parathyroid hormone (PTH), thyrotropin (TSH), 25-OH vitamin D, and total testosteron...

The effect of short term (12 weeks) physical exercise on serum total testosterone level was evaluated in 30 young male adults, aged 18-27 years (mean age 21.67±2.26 years). These medical students, having sedentary life style underwent heavy exercise by attaining heart rate 125-150 beats/min on bicycle ergometer for 15 min on alternate day basis amounted to 670 kilopond metre per minute work don...

Background: Women suffer more often from depression than men. Social research suggests that high androgen levels cause aggressive behavior in men and women, and consequently cause depression. The purpose of this study was to determine serum levels of androgens, especially testosterone, in patients with depression. Material and methods: In this case-controlled study, we measured serum testoste...

Diagnosis of testosterone deficiency is important to identify patients who might benefit from testosterone replacement therapy. Unfortunately, the diagnosis of hypogonadism may be a challenge for many practicing physicians, including endocrinologists and urologists. Signs and symptoms, such as sexual dysfunction, change in body composition, lethargy, and mood changes, are nonspecific and the av...

OBJECTIVE Association studies in men have shown that androgens are inversely related to fat measures, while the relation between sex steroids and lean mass remains unclear. We, therefore, investigated the associations between serum sex steroid levels and body composition in elderly men with a main focus on lean mass measures. DESIGN AND METHODS A cross-sectional survey of a population-based c...

OBJECTIVE To determine and compare the sex hormones, gonadotrophins and sex hormone binding globulin (SHBG) in healthy males of different age groups. METHODS One hundred eighty five consecutive healthy nonobese males of age 40-90 years were studied. Serum samples were assayed for total testosterone, estradiol, LH, FSH and SHBG estimation by radioimmunometric method. The subjects were divided ...

Despite its association with vascular events such as myocardial and cerebral infarction, polycythemia vera (PV) is characterized by low serum total cholesterol levels. Because several sex hormones are derived from cholesterol, statins may induce hypogodanism in male patients. Therefore, we assessed the relationship between serum total cholesterol and sex hormone levels according to gender. Medi...
