CONTEXT Age-related reduction of serum testosterone may contribute to the signs and symptoms of aging, but previous studies report conflicting evidence about testosterone levels and male mortality. No large prospective cohort study has determined a possible association between serum estradiol and mortality in men. OBJECTIVE The main objective was to examine the association between serum testo...

BACKGROUND Low level of testosterone may be associated with cardiovascular diseases in men, as some evidence suggests a protective role for testosterone in cardiovascular system. Little is known about the possible role of serum testosterone in response to reperfusion therapy in ST-elevation myocardial infarction (STEMI) and its relationship with ST-segment recovery. The present study was conduc...

Often, pathological Gleason Score (GS) and stage of prostate cancer (PCa) were inconsistent with biopsy GS and clinical stage. However, there were no widely accepted methods predicting upgrading and upstaging PCa. In our study, we investigated the association between serum testosterone and upgrading or upstaging of PCa after radical prostatectomy (RP). We enrolled 167 patients with PCa with bio...

Accurate measurement of testosterone is important for reproductive endocrinology research, but the validity of direct (nonextraction) testosterone immunoassays, developed and validated for human serum, has not been appraised for application to mouse serum or steroidogenic tissue extracts. Testosterone was measured in serum and extracts of testis or ovary from male and female wild-type mice by 2...

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...

The objective: to study the concentration of estradiol, progesterone, follicle-stimulating and luteinizing hormones, testosterone, prolactin cortisol in women with abnormal uterine bleeding (AUB) chronic psycho-emotional stress.Materials methods. We examined 100 reproductive age AUB stress (main group) 50 patients without (comparison group). 30 were included control group. diagnosis was made on...

PURPOSE Health related quality of life was assessed in patients with prostate cancer on androgen suppression therapy re-dosed based on serum testosterone, and observations were confirmed regarding the safety, efficacy and cost per patient treated with this method of re-dosing luteinizing hormone-releasing hormone agonists. MATERIALS AND METHODS The study comprised 22 patients with prostate ca...

INTRODUCTION Androgen deprivation therapy (ADT) is a mainstay of treatment against advanced prostate cancer (PC). As a treatment goal, suppression of plasma testosterone levels to <50 ng/dl has been established over decades. Evidence is growing though that suppression to even lower levels may add further clinical benefit. Therefore, we undertook a pooled retrospective analysis on the efficacy o...

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...
