objective: to evaluate the relationship between serum level of testosterone and sex hormone-binding globulin in men with type 2 diabetes. materials and methods: in this case-control study, forty men aged 40-70 with type 2 diabetes mellitus were randomly selected and compared with 40 non-diabetic men. the two groups were matched for their age and bmi. after complete observation and examination, ...

Recent studies have focused on the relationship between nocturia and serum testosterone because testosterone is thought to be an important factor of prostate growth. However, it remains unclear whether altered serum concentrations of testosterone is associated with an increased risk of nocturia because patients who were taking diuretics or who had a large prostate, which may precipitate nocturi...

In young men, chronic ingestion of 100 mg androstenedione (ASD), three times per day, does not increase serum total testosterone but does increase serum estrogen and ASD concentrations. We investigated the effects of ASD ingestion in healthy 30- to 56-yr-old men. In a double-blind, randomly assigned manner, subjects consumed 100 mg ASD three times daily (n = 28), or placebo (n = 27) for 28 days...

OBJECTIVE To determine correlation of serum total testosterone with body mass index (BMI) and waist hip ratio (WHR) in healthy adult males. METHODS A cross sectional study was conducted on 200 nonsmoker healthy males (aged 30-50 years) university employees. They were selected by convenience sampling technique after a detailed medical history and clinical examination including BMI and Waist Hi...

PURPOSE This study was conducted to investigate the relationship between serum total testosterone levels and scores on the Aging Male's Symptom (AMS) scale and the International Index of Erectile Function (IIEF) in men with erectile dysfunction with testosterone deficiency syndrome (TDS). MATERIALS AND METHODS From January 2005 to July 2008, 134 patients who complained of sexual dysfunction s...

Objective The main purpose of this study is to evaluate the effects of varicocelectomy on serum testosterone levels and semen quality in infertile men who suffer from varicocele. MaterialsAndMethods This prospective study enrolled 115 subjects with clinical varicocele grades II and III and 240 fertile men as the control group. Total volume of testosterone serum level (ng/dl) and semen quality w...

BACKGROUND AND OBJECTIVE Studies in men have demonstrated a correlation between serum concentrations of androgens and sex hormone binding globulin (SHBG) with the presence of impaired glucose tolerance, diabetes and metabolic syndrome. The aim of this study was to evaluate circulating levels of total testosterone, SHBG, and bioavailable testosterone in the cohort of the Asturias Study and their...

Background: To determine whether men with varicoceles have lower testosterone levels than those without and to ascertain if testosterone levels increase after varicocelectomy and or to determine whether the varicocele grade is related to the degree of improvement in serum testosterone levels after varicocelectomy and also older age is associated with improvements in testosterone after varicocel...
