57 citations
,
July 2016 in “The Journal of Sexual Medicine” This study concluded that 5α-reductase inhibitors were linked to increased sexual dysfunction in men with benign prostatic hyperplasia, but not in men with androgenetic alopecia.
27 citations
,
January 2016 in “Cellular Physiology and Biochemistry” This study found that the extract of Bidens pilosa L. improved dry eye symptoms associated with androgen deficiency in rats by enhancing tear production, stabilizing the tear film, and reducing lacrimal gland inflammation.

May 2015 in “Endocrinology” In this study, manipulation of the enzyme 5α-reductase type 2 in human hepatocytes altered lipogenesis, suggesting clinical implications for patients using 5α-reductase inhibitors by affecting glucocorticoid action on hepatic lipid metabolism.
44 citations
,
April 2015 in “PubMed” This study reports that clinical trials of finasteride for androgenic alopecia provide insufficient and systematically biased safety data, with most participants unrepresentative of those in pivotal trials that led to FDA approval.
93 citations
,
September 2014 in “Diabetes” This study found that male 5αR1 knockout mice and obese Zucker rats treated with finasteride showed increased insulin resistance and hepatic steatosis, potentially implicating 5α-reductase activity in metabolic liver disease development.
18 citations
,
March 2014 in “Journal of Pharmacological and Toxicological Methods” This study found that ovariectomized and finasteride-treated rats showed significant tear film deficiency and downregulation of sex steroid receptors in ocular tissues, suggesting potential models for studying dry eye disorders.
35 citations
,
January 2014 in “Postepy Dermatologii I Alergologii” This study found that increased dihydrotestosterone levels were observed in both androgenetic alopecia patients and controls, suggesting that follicle sensitivity to DHT may be more critical than DHT levels for alopecia development.
34 citations
,

66 citations
,
June 2013 in “Journal of Dermatological Treatment” This study reported no significant difference in efficacy or sexual dysfunction risk between 5α-reductase inhibitors and placebo for androgenetic alopecia, suggesting that dutasteride 0.5 mg may be considered pending further research.
44 citations
,
July 2012 in “Endocrine Practice” This review highlights the need for a deeper understanding of 5alpha-reductases and neuroactive steroids to reduce potential adverse effects of 5alpha-reductase inhibitors used for conditions like benign prostatic hyperplasia and androgenic alopecia, but reports no new clinical results.
29 citations
,
July 2012 in “The Journal of Sexual Medicine” In this study using a rat model, discontinuing dutasteride improved some relaxant responses but did not fully restore erectile function, indicating a potential time-dependent detriment of the drug.
