June 1991 in “The Journal of Clinical Endocrinology & Metabolism” This study found that caucasian subjects had higher serum levels of 5 alpha-reduced androgen metabolites compared to Chinese subjects, suggesting racial differences in 5 alpha-reductase activity and a potential mechanism for increased body hair in caucasian men.

April 1990 in “The Journal of Clinical Endocrinology & Metabolism” This study found that ovarian suppression significantly reduced serum testosterone and androstenedione in women with polycystic ovarian syndrome and idiopathic hirsutism, with hair growth rates decreasing more in polycystic ovarian syndrome.

April 1990 in “The Journal of Clinical Endocrinology and Metabolism” This study found that finasteride significantly suppresses serum dihydrotestosterone levels at all tested doses in normal male volunteers without significant adverse effects.
51 citations
,
November 1988 in “The Journal of Clinical Endocrinology & Metabolism” This study found that serum 3 alpha-Adiol-G levels in men are significantly associated with chest hair density and acne, indicating its role in reflecting androgen activity in peripheral tissues.
66 citations
,
October 1987 in “The Journal of clinical endocrinology and metabolism/Journal of clinical endocrinology & metabolism” This study found that serum 3 alpha-diol G levels in women with idiopathic hirsutism correlated well with their clinical response to treatment, suggesting its usefulness in evaluating treatment outcomes.
35 citations
,
May 1986 in “Clinics in endocrinology and metabolism” This study concludes that high skin 5α-reductase activity may contribute to hirsutism, but the specific regulatory mechanisms and genetic factors remain unclear.
142 citations
,
February 1985 in “Fertility and sterility” This study found that spironolactone reduced serum androstenedione and anagen hair shaft diameter in hirsute patients but did not significantly alter unbound testosterone levels, suggesting its effects are primarily peripheral.
179 citations
,
May 1982 in “The Journal of clinical investigation/The journal of clinical investigation” This study found that plasma 3 alpha-diol glucuronide was markedly elevated in women with idiopathic hirsutism, suggesting it may be a marker of peripheral androgen action.
