PURPOSE The aim of the present study aimed to evaluate the effect of testosterone on cardiovascular disease by using the Framingham Risk Score (FRS) in patients with sexual dysfunction. MATERIALS AND METHODS A total of 308 men with sexual dysfunction were enrolled in this study. Clinical assessments included the 15-item International Index of Erectile Function (IIEF), blood pressure measureme...

In this review we identify whether problems encountered in urology, such as erectile dysfunction, have a bearing on general health, in particular cardiovascular health. Testosterone, traditionally regarded as the hormone subserving male reproductive and sexual functioning, appears to have a much wider role. Recent findings show that testosterone is involved in the metabolic control of glucose a...

The aim of this study was to examine acute hormonal responses after different sequences of an upper-body resistance-exercise session. Twenty men completed 2 sessions (3 sets; 70% 1-repetition maximum; 2 min passive rest between sets) of the same exercises in opposite sequences (larger to smaller vs. smaller to larger muscle-group exercises). Total testosterone (TT), free testosterone (FT), test...

Testosterone (T) is a biologically important androgen that demonstrates a widely-known natural decline with advancing age. The use of salivary T (sal-T), as a determinant of systemic T, has shown promising results in recent years. However, the strength of the salivary-serum T relationship may be affected by measurement method and binding capacity with salivary proteins. The potential influence ...

OBJECTIVE To describe patterns of testosterone prescribing in Australia over the past two decades by state or territory and by product type. DESIGN AND SETTING Observational analysis of testosterone prescribing data obtained from two independent data sources--the Pharmaceutical Benefits Scheme (PBS) and IMS, a source of commercial pharmaceutical sales data. MAIN OUTCOME MEASURES Temporal tr...

PURPOSE Testosterone (T) exerts different effects on the cardiovascular system. Despite this knowledge, the acute vascular effect of androgen remains still poorly understood. METHODS We investigated the acute effects of T on vascular function in ten men (18-40 years age) with hypogonadism and severe hypotestosteronemia [serum total testosterone (TT) = 0.6 ± 0.3 ng/mL]. In a 4-day double-blind...

BACKGROUND Type 2 diabetes is a risk factor for testosterone deficiency and impaired sex steroid status. Some studies also investigated the association of testosterone level with diabetes risk in men, but reported controversial findings. To clarify this issue, we conducted a systematic review and meta-analysis. METHODS PubMed, EMBASE and Web of Science were searched for eligible cohort or nes...

STUDIES over the last decade have shown that the male hormone, testosterone, declines with age in men (1,2). This decline is associated with a decrease in libido, muscle mass and strength, leptin levels, bone mineral density (BMD), hematocrit, and cognition (3–6). It also has been recognized that total testosterone is a poor measurement of gonadal status because of the increase in sex hormone b...

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...

The interrelations between testosterone, insulin and melatonin levels in males with metabolic syndrome (MS) are still not clarified, especially in young age groups. The aim of the present study was to compare the testosterone serum levels in young men with MS to those in healthy controls, and to determine the possible changes in their melatonin rhythm, as well as the relation between melatonin,...
