Dehydroepiandrosterone sulfate, abbreviated as DHEA sulfate or DHEA-S, also known as androstenolone sulfate, is an endogenous androstane steroid that is produced by the adrenal cortex. [1] It is the 3β- sulfate ester and a metabolite of dehydroepiandrosterone (DHEA) and circulates in far greater relative concentrations than DHEA. [ 2 ]
3β-HSD II mediates three parallel dehydrogenase/isomerase reactions in the adrenals that convert Δ 4 to Δ 5 steroids: pregnenolone to progesterone, 17α-hydroxypregnenolone to 17α-hydroxyprogesterone, and dehydroepiandrosterone (DHEA) to androstenedione. 3β-HSD II also mediates an alternate route of testosterone synthesis from androstenediol in the testes. 3β-HSD deficiency results in ...
Prasterone, also known as dehydroepiandrosterone (DHEA) and sold under the brand name Intrarosa among others, is a medication as well as over-the-counter dietary supplement which is used to correct DHEA deficiency due to adrenal insufficiency or old age, as a component of menopausal hormone therapy, to treat painful sexual intercourse due to vaginal atrophy, and to prepare the cervix for ...
Plasma levels of DHEA in adult men are 10 to 25 nM, in premenopausal women are 5 to 30 nM, and in postmenopausal women are 2 to 20 nM. [25] Conversely, DHEA-S levels are an order of magnitude higher at 1–10 μM. [25] Levels of DHEA and DHEA-S decline to the lower nanomolar and micromolar ranges in men and women aged 60 to 80 years. [25]
Prasterone sulfate (brand names Astenile, Mylis, Teloin, others), also known as dehydroepiandrosterone sulfate (DHEA-S), is a naturally occurring androstane steroid which is marketed and used in Japan and other countries as a labor inducer in the treatment of insufficient cervical ripening and dilation during childbirth.
Adrenal steroids are steroids that are derived from the adrenal glands.They include corticosteroids, which consist of glucocorticoids like cortisol and mineralocorticoids like aldosterone, adrenal androgens like dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S), and androstenedione (A4), and neurosteroids like DHEA and DHEA-S, as well as pregnenolone and pregnenolone sulfate (P5-S).
A study has revealed that serum progesterone concentrations in boys (10 days to 18 years old) with 21-hydroxylase deficiency reached levels up to 10.14 ng/mL, i.e. similar to female luteal values, while in the control group of boys average level was 0.07 ng/mL (0.22 nmol/L), with values ranging from 0.05 to 0.40 ng/mL. [38]
The exact mechanism of action of these hormones is unclear, and may involve both direct effect on the tumor cells (suppression of estrogen receptor levels, alteration of hormone metabolism, direct cytotoxicity) and indirect endocrine effects (suppression of adrenal androgen production and plasma estrone sulfate formation).
