Testosterone RIA Test
Description:...y the testes with only a small amount derived from peripheral conversion of
androstenedione [2]. In adult women, it has been estimated that over 50% of serum testosterone is derived from peripheral conversion of
androstenedione secreted by the adrenal and ovary, with the remainder from direct secretion...

17a-OH Progesterone RIA Test
Description:...ted to cortisol by the sequential actions of 21-hyroxylase and 11-hyroxylase. In both the adrenal glands and ovaries, 17alpha-OH-P can be converted to
androstenedione (a precursor for testosterone and estradiol), by 17,20-lyase. Measurement of circulating 17alpha-OH-P levels is a standard tool for clinical assessmen...

The dietary supplement genistein can undermine breast cancer treatment
...ast cancer are post-menopausal, so their ovaries are no longer producing normal levels of estrogen. Other tissues, however, produce a steroid hormone,
androstenedione (AD), which with the help of aromatases is converted to testosterone and estrogens. The estrogens produced from AD can stimulate the growth of some ...
Sex hormones link to heart risk
...ars, from the Young Men Cardiovascular Association study. The researchers looked at ways that the sex hormones - estradiol, estrone, testosterone and
androstenedione - interacted with three major risk factors of heart disease (cholesterol, blood pressure and weight).
They found that two of these sex hormones ...
