June 2017 in “Steroids” This study evaluated novel steroid compounds for their ability to inhibit 5α-reductase, showing that compound 16a significantly reduced rat prostate weight more than epristeride and exhibited excellent in vitro inhibitory potency, indicating its potential as a lead candidate for further benign prostatic hyperplasia drug research.
January 2023 in “Bioorganičeskaâ himiâ” This study found that a new deoxycholic acid derivative may offer a similar prostatoprotective effect to finasteride with lower toxicity in rat models.
February 2017 in “대한피부과학회지” This case report describes a 52-year-old man with androgenic alopecia who experienced improvement after adding low-dose dutasteride to long-term finasteride treatment when the initial therapy's effectiveness waned.
July 2026 in “Journal of Craniofacial Surgery” This study found that silencing SRD5A2 and applying melatonin significantly boosted proliferation and migration of human hair follicle stem cells without causing differentiation, while increasing MT1 expression and reducing 5-alpha-reductase levels.
25 citations
,
September 1998 in “The Journal of Steroid Biochemistry and Molecular Biology” This study concludes that rhesus macaques are a suitable model for testing the pharmacological properties of finasteride and other 5aR inhibitors, due to their biochemical similarity to humans.

May 1996 in “The Journal of clinical endocrinology and metabolism/Journal of clinical endocrinology & metabolism” This study reported that 5 alpha-reductase type 2 is the predominant enzyme in pubic skin fibroblasts across normal men, women, and hirsute patients, suggesting potential treatment options for idiopathic hirsutism.
29 citations
,
January 1996 in “Journal of Pharmaceutical Sciences” This study developed a theoretical model that suggests finasteride may completely inhibit 5AR type 2, but not sufficiently suppress type 1, leading to only partial reduction of dihydrotestosterone at clinical doses.
14 citations
,
