,
November 2021 in “International journal of molecular sciences” In this study, germ-free male mice showed altered levels of certain neuroactive steroids in the brain and periphery, suggesting microbiota may influence neuroendocrine pathways that support brain functioning.
22 citations
,
September 1994 in “The Journal of Clinical Endocrinology and Metabolism” This study found that three months of oral finasteride treatment significantly decreased dihydrotestosterone levels and hair growth in hirsute women without negatively affecting gonadotropin secretion.
35 citations
,
April 2013 in “Sexual medicine reviews” This review found that 5α-reductase inhibitors are associated with slightly increased rates of sexual dysfunction, gynecomastia, and mood disorders, but the true significance and persistence of these effects remain unclear.
5 citations
,
January 1983 in “PubMed” This study determined that in axillary hair of mature males and females, free androgen steroids are primarily produced by sebaceous glands, while C19-steroid sulphates are products of sweat glands.
11 citations
,
November 2009 in “Journal of steroid biochemistry and molecular biology/The Journal of steroid biochemistry and molecular biology” This study found that bolandiol increased lean body mass and bone mineral density in castrate adult male rats, exhibiting tissue selectivity and acting through multiple receptor pathways with less potency compared to other androgens.
50 citations
,
August 1985 in “Journal of steroid biochemistry/Journal of Steroid Biochemistry” This study found that spironolactone directly inhibits 5 alpha-reductase activity in hirsute women, resulting in decreased conversion of testosterone to dihydrotestosterone, which may contribute to its therapeutic effects.
51 citations
,
January 2001 in “Biological & Pharmaceutical Bulletin” This study found that the aqueous ethanol extract of Myricae Cortex demonstrated in vitro testosterone 5alpha-reductase inhibitory activity and in vivo anti-androgenic effects in mouse and hamster models.
