,
August 2016 in “Scientific Reports” This animal study found that Cinnamomi cortex water extract reduced prostate weight and improved histological changes in a benign prostatic hyperplasia model, suggesting potential as a treatment.
39 citations
,
January 2019 in “The World Journal of Men's Health” Testosterone replacement therapy can prevent men from fathering children and should not be used by those wanting to stay fertile.
36 citations
,
January 2014 in “The Journal of Sexual Medicine” This study found that transdermal testosterone significantly increased the frequency of satisfactory sexual events in women experiencing SSRI/SNRI-related loss of libido, but did not improve overall sexual self-rating scores.
36 citations
,
October 2009 in “Journal of Investigative Dermatology” This study suggests that in SZ95 sebocytes, a pathway for DHT biosynthesis does not require testosterone as an intermediate, potentially impacting the treatment of androgen-sensitive skin conditions.
34 citations
,
February 1993 in “Journal of steroid biochemistry and molecular biology/The Journal of steroid biochemistry and molecular biology” This study found that 4-MA is a potent inhibitor of testosterone 5α-reductase in human tissues, promising potential for treating androgen-dependent skin conditions like male pattern baldness.
31 citations
,
January 1995 in “The American journal of medicine” This article reviews the role of 5α-reductase in cutaneous hyperandrogenism and the potential of 5α-reductase inhibitors and antiandrogens in treating conditions like hirsutism and male-pattern baldness, reporting no clinical results.
28 citations
,
October 1998 in “Baillière's clinical endocrinology and metabolism” This review examines age-related changes in androgen levels in women and explores the rationale for testosterone replacement therapy, but it reports no new clinical findings.
27 citations
,
February 2017 in “Biomedicine & Pharmacotherapy” This study found that white wax and its extract may promote hair growth in a mouse model of androgenetic alopecia by inhibiting 5α-reductase activity and increasing cell proliferation, with efficacy surpassing finasteride.
26 citations
,
December 2020 in “Cleveland Clinic Journal of Medicine” This review examines the roles of androgens in women's health and provides recommendations for androgen therapy but reports no new results.

25 citations
,
August 2006 in “Human Reproduction” This study found that the GGC repeat length significantly influenced testosterone levels in oral contraceptive users from high-risk breast cancer families, and homozygosity for short alleles may be linked to increased breast cancer risk.
25 citations
,
