They allow the athlete to train harder and longer at any given period. Anabolic steroids are mostly testosterone (male sex hormone) and its derivatives. Examples of anabolic steroids include: testosterone, dihydrotestosterone, androstenedione (andro), dehydroepiandrosterone (DHEA), clostebol, nandrolone....
androstenedione, and numerous hormones and metabolites. It is primarily metabolized in the liver. Its sedative and calming central nervous system effect is a property of the metabolites acting through GABA receptors rather than progesterone itself. The effect is seen to be both quantitative and qualita...
In postmenopausal women, the effect of obesity can be explained by increased extraglandular conversion of androstenedione to estrone by aromatase enzymes in the body's fat deposits. The effect of height and premenopausal body habitus on breast cancer risk is less well understood but is probably ...
In 1999, Mike Piazza publicly acknowledged briefly ingesting the steroid hormone androstenedione early in his career when it was available over the counter and not yet banned by Major League Baseball. I was among the 83 percent of Hall voters last year who gave the best hitting catcher in ...
Of the nearly 30 steroid hormones produced by the adrenal cortex, the principal ones include aldosterone (a mineralocorticoid), cortisol (a glucocorticoid) and various sex hormones and their precursors (DHEA, androstenedione). The mineralocorticoids play an essential role in regulating potassium and ...
Women who were defined as oestrogen sufficient (E2 > 140 pmol/l) had higher serum androstenedione, and lower urinary free cortisol levels, than women who were oestrogen deficient (E2 < 140 pmol/l). Six of the 13 women (46%) had ovarian morphology suggestive of PCO, four of six oestrogen...
To ascertain the potential SRD5As activity, we cultured C4-2 and C4-2AT6 cells with the steroid precursors modified by stable isotope:13 C-[2,3,4 ] -androstenedione (13C-A-dione). The sequential biosynthesis of13 C-[2,3,4 ] -dihydrotestosterone (13C-DHT) and13 C-[2,3,4 ] -...
Results: During the first cycle of treatment, 104 patients (36.8%) were resistant to 50 mg/day of CC. Univariate regression analysis showed that patients who resisted 50 mg/day of CC had significantly higher BMI, waist circumference, serum levels of AMH, total testosterone, 螖4-androstenedione...
Varady and her team found that levels of sex-binding globulin hormone, a protein that carriesreproductive hormonesthroughout the body, was unchanged in the dieters after eight weeks. The same held true for both testosterone and androstenedione, asteroid hormonethat the body uses to produce both te...
