55 citations
,

49 citations
,
October 1988 in “The Journal of Clinical Endocrinology & Metabolism” This study found that low doses of leuprolide effectively suppressed serum estradiol and LH response, while higher doses were needed to suppress testosterone and reduce hair growth in hirsute women.
37 citations
,
May 2018 in “Transgender health” This study found that oral estradiol was generally effective in achieving target 17-β estradiol levels in transgender women, but often failed to suppress testosterone adequately, with variability in individual responses.
36 citations
,
May 2017 in “The journal of sexual medicine” In this retrospective study, cyproterone acetate treatment in late-pubertal trans-girls was found to be generally safe and led to mild feminizing effects, with more rapid feminization occurring when combined with estrogens.
34 citations
,
November 2017 in “Gynecological Endocrinology” This report describes a case of meningioma in a transwoman treated long-term with estradiol and cyproterone acetate, suggesting possible concern over female sex steroids and meningioma risk.
32 citations
,
December 1999 in “Journal of Investigative Dermatology Symposium Proceedings” This study found that the effectiveness of 17-beta-estradiol in inhibiting hair growth depends on its application method, and noted significant sex differences in response to 17-alpha-estradiol in male and female mice.
31 citations
,
January 1989 in “The Prostate/The prostate” This study found that early treatment with estradiol or dihydrotestosterone significantly reduced prostate adenocarcinoma development in Lobund-Wistar rats, while later treatments were ineffective.
25 citations
,
February 1977 in “American Journal of Veterinary Research” This study concluded that exposing anestrous brood mares to a 16-hour photoperiod in early December led to endocrinologically normal estrous cycles starting within two months, enabling earlier breeding and foaling.
22 citations
,
July 1990 in “Acta Dermato Venereologica” In this study, high concentrations of dihydrotestosterone and testosterone reduced the growth of human hair follicle cells in vitro, while high estradiol levels increased their growth.

,
January 2003 in “Skin pharmacology and physiology” This study found that dutasteride completely suppressed the formation of 5alpha-dihydro metabolites in cultured human skin cells, suggesting its potential use in acne and androgenetic alopecia.
19 citations
,

,
March 2002 in “The journal of investigative dermatology/Journal of investigative dermatology” In this study, 17β-estradiol increased VEGF production in differentiated THP-1 cells, while dihydrotestosterone counteracted this effect by modulating adenylate cyclase activity.

,
August 2014 in “International Journal of Women's Health” The estradiol valerate/dienogest oral contraceptive helps with heavy periods, may improve acne and symptoms in PCOS, and doesn't affect sexual function.
14 citations
,
August 1943 in “Archives of Dermatology” This study reported that applying natural or artificial folliculoid compounds to mouse skin caused estrous-like changes in internal sex organs, but did not lead to cancerous skin changes.
