PURPOSE OF REVIEW There is increasing interest in age-related changes in sex hormone levels as a potentially treatable cause of ill-health in men. Relationships between androgens and cardiovascular disease will be discussed, with particular attention to more recently published research. RECENT FINDINGS In middle-aged and older men, lower testosterone levels are associated with insulin resista...

The role of androgen treatment in women remains controversial. The proposed "Female Androgen Insufficiency Syndrome" (Fertility and Sterility, April 2002) describes a number of non-specific symptoms including unexplained fatigue, decreased well being/dysphoric mood and/or blunted motivation and diminished sexual function. An estimated 40% of women experience sexual dysfunction, highlighting the...

There is increasing interest in the role of androgens in the treatment of women but little is known about their long-term safety. There are also very few studies on testosterone therapy and breast cancer risk. However, some observations support the concept that androgens may counteract the stimulatory effects of estrogen and progestogen in the mammary gland. Mammographic breast density and brea...

difficult diagnosis in endocrinology, gynecology, and reproductive medicine. to help solve this issue, the rotterdam consensus conference proposed to include the ultrasonographic follicle count as a new diagnostic criterion, in addition to hyperandrogenism and oligo-anovulation. unfortunately, its assessment does not offer sufficient reliability worldwide. objective: to explore the possible rol...

The biological activity of androgens is thought to occur predominantly through binding to intracellular androgen-receptors, a member of the nuclear receptor family, that interact with specific nucleotide sequences to alter gene expression. This genomic-androgen effect typically takes at least more than half an hour. In contrast, the rapid or non-genomic actions of androgens are manifested withi...

Androgens are widely acknowledged to be central to the pathogenesis of benign prostatic hypertrophy (BPH). However, BPH increases in prevalence as men age, at precisely the stage of life when plasma androgens are decreasing. The decrease in total plasma androgens is amplified by an age-related increase in plasma sex hormone-binding globulin (SHBG) that results in a relatively greater decrease i...

The roles of androgens on cardiovascular physiology and pathophysiology are controversial as both beneficial and detrimental effects have been reported. Although the reasons for this discrepancy are unclear, multiple factors such as genetic and epigenetic variation, sex-specificity, hormone interactions, drug preparation and route of administration may contribute. Recently, growing evidence sug...

OBJECTIVE To establish the relationship between androgens and cardiovascular disease (CVD) risk factors in the menopausal transition. METHODS A total of 124 women were divided into four groups: 29 premenopausal (PreM), 35 women in the menopausal transition still menstruating (MTM), 29 women in the menopausal transition with 3-6 months amenorrhea (MTA), and 31 postmenopausal women (PostM). Lev...

The role of androgens in cardiovascular disease is uncertain. We aimed to determine the vascular effects of androgen suppression in men with prostate cancer. Arterial stiffness (or 'compliance') was measured in 16 men (71+/-9 years, mean+/-S.D.) prior to, and 3 months after, complete androgen suppression with gonadotrophin-releasing hormone analogues as treatment for prostate cancer. Fifteen co...
