February 2000 in “Endocrinology and metabolism/American journal of physiology: endocrinology and metabolism” This study found that topical estradiol inhibits hair growth in mice by preventing the hair follicle's transition from resting to growth phase, a process reversible with an estrogen receptor antagonist.
55 citations
,
June 2012 in “Steroids” This study found that testosterone modulates vascular cell behavior through direct actions that do not rely on its conversion to estradiol.
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.
