Background: Testosterone (T) and estradiol (E2) play a critical role in male sexual function being essential for modulating libido and erectile function. We hypothesized that an imbalance of T/E2 ratio may be an important factor leading to the development of low sexual desire in ageing men. ...
Muscle mass and strength losses during aging may be associated with declining levels of serum testosterone (T) in men. Few studies have shown a direct relationship between T and muscle mass and strength. Subjects were 262 men, aged 24-90 yr, from the Baltimore Longitudinal Study of Aging, wh...
Abstract. Context: Little is known about testosterone (T) levels and their determinants in women of late postmenopausal age.Objective: We describe levels o
Background There has never been a large scale population-based study of serum levels of total testosterone (TT) and free testosterone (FT) in Japanese men. Methods We determined serum levels of TT and FT of 1120 Japanese men aged 40–79 years using radioimmunoassay (RIA), as a part of a...
Sex hormone-binding globulin (SHBG), estradiol (E2), percent free E2, percent of E2 bound to SHBG, and testosterone (T) were evluated in 28 ovulatory women during human menopausal gonadotropin-stimulated cycles for in vitro fertilization. Patients were divided into two categories: low responders...
Conclusion We present a relatively simple UF coupled LC-MS/MS definitive method that measures serum free testosterone. The method is relatively fast, reliable and is suitable for the routine clinical laboratory practice. 展开 关键词: Testosterone Serum free hormone LC-MS/MS Ultrafiltration Immunoassay...

The effects of aging in normal men on bioavailable testosterone and luteinizing hormone secretion: response to clomiphene citrate. Serum (T) levels in men decline with age while serum LH levels, as measured by , increase. To assess if the decline in serum T levels in healthy men is paralleled...
