Objective—Because population-based data are lacking, we assessed the cross-sectional association between serum testosterone levels and endothelial function, as measured by flow-mediated dilation (FMD) and nitroglycerin-mediated dilation (NMD) of the brachial artery, in men from the population-based Study of Health in Pomerania. Methods and Results—Personal characteristics, including major cardi...

Background: Varicocele suggests that in addition to effects on spermatogenesis, varicocele also impairs testicular Leydig cell function with a consequential decrease in testosterone production; correction of the varicocele may result in improved serum testosterone levels. Materials and Methods: We measured preoperative serum testosterone levels in 40 infertile men with varicoceles varicocele (g...

Osteocalcin (Ocn) and testosterone play important roles in male skeleton. However, the concentrations of serum osteocalcin and testosterone have never been systematically compared between populations with and without primary male osteoporosis, a common skeletal disorder in adult males. We searched the PubMed, Embase, and Cochrane Library for relevant studies. A meta-analysis was performed to co...

PURPOSE To investigate patients who had transrectal ultrasonography (TRUS)-guided prostate biopsy to define the role of the serum testosterone level in predicting prostate cancer risk and its association with a high Gleason score. MATERIALS AND METHODS A total of 568 patients who underwent prostate biopsy were entered in this study. We divided the patients into two groups according to serum t...

OBJECTIVE The aim of this study was to investigate the effect of serum gonadotropin and total testosterone levels on semen parameters. MATERIALS AND METHODS Three hundred and eighty-two patients that applied to a male infertility polyclinic were included in our study. Serum gonadotropin and total testosterone levels and semen parameters of the patients were analyzed during the first visit to ...

The effectiveness of orally ingested androstenediol in raising serum testosterone concentrations may be limited because of hepatic breakdown of the ingested androgens. Because androstenediol administered sublingually with cyclodextrin bypasses first-pass hepatic catabolism, we evaluated the acute hormonal response to sublingual cyclodextrin androstenediol supplement in young men. Eight men (22....

Background: The relation between coronary artery disease (CAD) and the levels of serum androgen has been revealed in various population studies. The Gensini coronary scoring system is used to evaluate the degree of coronary stenosis, taking into account its location and producing a numerical score. The aim of the study was to explore the association between serum testosterone levels and both th...
