The results of the blood tests on Vera Leizd showed that her level of testosterone was normal but that her serum dehydroepiandrosterone sulfate (DHEAS) level was significantly elevated. Which tissue was the most likely source of the androgens that caused Vera s hirsutism (a male pattern of secondary sexual hair growth) ... [Pg.648]

Men taking carbamazepine had mean low serum concentrations of dehydroepiandrosterone and a high SHBG concentration. Moreover, 18% of men taking carbamazepine for epilepsy reported reduced libido, impaired potency, or both. [Pg.589]

Gynecomastia was occasionally observed in men when ketoconazole first became available. Ketoconazole has a marked effect on steroid concentrations, including a change in the testosterone/estradiol ratio, and this is most likely to be the basis of the gynecomastia. A lowering of testosterone serum concentrations and a reduced response of testosterone concentrations to human gonadotropin have been shown (SED-11, 573) (583). Various studies have shown suppression of testosterone, androste-nedione, and dehydroepiandrosterone, with reciprocal increases in gonadotrophins. [Pg.614]

Azizi et al. (1995) investigated changes in serum concentrations of reproductive hormones and sperm counts in men who had been exposed to sulfur mustard during wartime. In 16 individuals, serum free and total testosterone and dehydroepiandrosterone were markedly decreased in the first five weeks after exposure but levels returned to normal by 12 weeks. In 28 of 42 men evaluated one to three years after exposure, sperm counts were less than 30 million ceUs/mL and follicle-stimulating hormone was increased compared to controls having sperm counts above 60 million cells/mL. Testicular biopsy of the test subjects revealed partial or complete arrest of spermatogenesis. [Pg.266]

Dehydroepiandrosterone (DHEA), a naturally occurring precursor of endogenous testosterone synthesis, assnmed national attention following its use in professional baseball. Unlike the parenteral administration of testosterone, however, DHEA does not produce a notable elevation in serum testosterone levels or enhance skeletal mnscle hypertrophy.Several adverse effects were reported and the International Olympic Committee considers DHEA an illegal steroid, banning its use. A recent analysis of sixteen commercial DHEA products revealed that only half the products contained the actual amount of DHEA stated on the product label, with actual levels varying between 0% and 150% of the label content. ...
