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]
In premenopausal women, 40 to 75% of circulating testosterone is derived from peripheral metabolism of DHEA-S, and in postmenopausal women, over 90% of estrogens, mainly estrone, are derived from peripheral metabolism of DHEA-S. [2] A study found that administration of exogenous DHEA-S in women who were pregnant increased circulating levels of ...

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 ...
[1] [2] It is the 3α-epimer of dehydroepiandrosterone (DHEA; androst-5-en-3β-ol-17-one) and the 5(6)-dehydrogenated and non-5α-reduced analogue of androsterone (5α-androstan-3α-ol-17-one). [2] DHA is produced in and secreted from the adrenal glands , along with other weak androgens like DHEA, androstenediol , and androstenedione .
Regarding the relative contributions of ovaries and adrenal glands to female androgen levels, in a study with six menstruating women the following observations have been made: [8] Adrenal contribution to peripheral T, DHT, A, DHEA and DHEA-S is relatively constant throughout the menstrual cycle.
Levels of DHEA-S, a major adrenal androgen, throughout life in humans. [1]Adrenopause is the decline in secretion and levels of adrenal androgens such as dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA-S) from the zona reticularis of the adrenal glands with age.
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).
