7α-Hydroxydehydroepiandrosterone (7α-hydroxy-DHEA; 7α-OH-DHEA), also known as 3β,7α-dihydroxyandrost-5-ene-17-one, is an endogenous, naturally occurring steroid and a major metabolite of dehydroepiandrosterone (DHEA) that is formed by CYP7B1 (steroid 7α-hydroxylase) in tissues such as the prostate gland and by CYP3A4 in the liver.{{cite web | url = http://www.hmdb.ca/metabolites/HMDB04611 | title = Metabocard for 7α-Hydroxydehydroepiandrosterone (HMDB04611)| work = Human Metabolome Database }}{{cite journal | vauthors = Miller KK, Al-Rayyan N, Ivanova MM, Mattingly KA, Ripp SL, Klinge CM, Prough RA | title = DHEA metabolites activate estrogen receptors alpha and beta | journal = Steroids | volume = 78 | issue = 1 | pages = 15–25 | year = 2013 | pmid = 23123738 | pmc = 3529809 | doi = 10.1016/j.steroids.2012.10.002 }} The major metabolic pathway of DHEA outside the liver is via 7-hydroxylation into 7α-OH-DHEA and 7β-OH-DHEA.{{cite journal | vauthors = Li H, Liu HM, Ge W, Huang L, Shan L | title = Synthesis of 7alpha-hydroxy-dehydroepiandrosterone and 7beta-hydroxy-dehydroepiandrosterone | journal = Steroids | volume = 70 | issue = 14 | pages = 970–3 | year = 2005 | pmid = 16143359 | doi = 10.1016/j.steroids.2005.07.006 | s2cid = 53294855 | quote = he major metabolic pathway for DHEA in extra-hepatic tissues is via 7-hydroxylation [18], [19] and [20].}} 7α-OH-DHEA has weak estrogenic activity, selectively activating the estrogen receptor ERβ. In addition, 7α-OH-DHEA may be responsible for the known antiglucocorticoid effects of DHEA.{{cite journal | vauthors = Attal-Khémis S, Dalmeyda V, Michot JL, Roudier M, Morfin R | title = Increased total 7 alpha-hydroxy-dehydroepiandrosterone in serum of patients with Alzheimer's disease | journal = J.

Serum levels of 7α-OH-DHEA have been found to be significantly elevated in patients with Alzheimer's disease. It is unclear what significance this may have, if any.{{cite book|author=Ronald Ross Watson|title=DHEA in Human Health and Aging|url=https://books.google.com/books?id=COZH22RYMT4C&pg=PA437|date=22 July 2011|publisher=CRC Press|isbn=978-1-4398-3883-9|pages=437–}}

7α-OH-DHEA is on the World Anti-Doping Agency list of prohibited substances in sporting.{{cite web | url = https://www.wada-ama.org/sites/default/files/wada_2019_english_prohibited_list.pdf | title = World Anti-Doping Agency Prohibited List 2019 }}
