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 ]
Levels of DHEA and DHEA-S decline to the lower nanomolar and micromolar ranges in men and women aged 60 to 80 years. [25] DHEA levels are as follows: [59] Adult men: 180–1250 ng/dL; Adult women: 130–980 ng/dL; Pregnant women: 135–810 ng/dL; Prepubertal children (<1 year): 26–585 ng/dL; Prepubertal children (1–5 years): 9–68 ng/dL
Hyperandrogenism is a medical condition characterized by high levels of androgens.It is more common in women than men. [4] Symptoms of hyperandrogenism may include acne, seborrhea, hair loss on the scalp, increased body or facial hair, and infrequent or absent menstruation.
As such 17α-hydroxypregenolone represents an intermediary in the Δ 5 pathway that leads from pregnenolone to DHEA. 17α-Hydroxypregneolone is also converted to 17α-hydroxyprogesterone, a prohormone for glucocorticosteroids and androstenedione through the activity of 3α-hydroxysteroid dehydrogenase.
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 ...
Pregnenolone and its 3β-sulfate, pregnenolone sulfate, like dehydroepiandrosterone (DHEA), DHEA sulfate, and progesterone, belong to the group of neurosteroids that are found in high concentrations in certain areas of the brain, and are synthesized there.
16α-Hydroxydehydroepiandrosterone (16α-hydroxy-DHEA or 16α-OH-DHEA) is an endogenous metabolite of dehydroepiandrosterone (DHEA). Both 16α-OH-DHEA and its 3β-sulfate ester, 16α-OH-DHEA-S, are intermediates in the biosynthesis of estriol from dehydroepiandrosterone (DHEA). [1] 16α-OH-DHEA has estrogenic activity. [2]
Major examples include the pregnanes pregnenolone sulfate (PS), epipregnanolone, and isopregnanolone (sepranolone), the androstanes dehydroepiandrosterone (DHEA; prasterone), and dehydroepiandrosterone sulfate (DHEA-S; prasterone sulfate), and the cholestane 24-hydroxycholesterol (NMDA receptor-selective; very potent).
