research Differential expression of steroid 5α-reductase isozymes and association with disease severity and angiogenic genes predict their biological role in prostate cancer
SRD5A1 is crucial in advanced prostate cancer, and blocking both SRD5A1 and SRD5A2 is more effective than targeting SRD5A2 alone.
research Persistent erectile dysfunction in men exposed to the 5α-reductase inhibitors, finasteride, or dutasteride
Using finasteride or dutasteride may cause long-lasting erectile dysfunction.
research Human type 3 5α-reductase is expressed in peripheral tissues at higher levels than types 1 and 2 and its activity is potently inhibited by finasteride and dutasteride
Type 3 5α-reductase is more common and finasteride and dutasteride strongly inhibit it.
research Azasteroids as inhibitors of testosterone 5α-reductase in mammalian skin
Certain 4-azasteroids are effective at blocking the enzyme that processes testosterone in human skin and could help treat acne, excessive hair growth, and male pattern baldness.
research Finasteride, a Type 2 5α-reductase inhibitor, in the treatment of men with androgenetic alopecia
Finasteride effectively treats male hair loss, improving growth and density.
research Reversible decreases of fertility in male Sprague-Dawley rats treated orally with finasteride, a 5α-reductase inhibitor
Finasteride temporarily lowers male rat fertility without affecting libido.
research Activity of type 1 5α-reductase is greater in the follicular infrainfundibulum compared with the epidermis
The enzyme type 1 5α-reductase is more active in the hair follicle's lower part than in the skin's outer layer.
research The circulating dihydrotestosterone/testosterone ratio is increased by gut microbial 5α-reductase activity in females
Women have a higher DHT/testosterone ratio than men, possibly due to gut bacteria activity.
research Regulatory Effects of Thai Rice By-Product Extracts from Oryza sativa L. cv. Bue Bang 3 CMU and Bue Bang 4 CMU on Melanin Production, Nitric Oxide Secretion, and Steroid 5α-Reductase Inhibition
BB4CMU rice bran oil may help treat hair loss and gray hair.
research In Silico Screening of DrugBank Compounds as Potential Inhibitors for Human Steroid 5α-Reductase 2 for Androgen-Related Diseases
Stiripentol shows promise as a potential treatment for androgen-related diseases but needs more testing.
research Caffeic acid N-[3,5-bis(trifluoromethyl)phenyl] amide as a non-steroidal inhibitor for steroid 5α-reductase type 1 using a human keratinocyte cell-based assay and molecular dynamics
Compound 4 is a promising treatment for hair loss with low toxicity.
research External genitalia abnormalities in male rats exposed in utero to finasteride, a 5α-reductase inhibitor
Finasteride exposure in pregnancy causes genital abnormalities in male rats.
research Sex dependent influence of a functional polymorphism in steroid 5‐α‐reductase type 2 (SRD5A2) on post‐traumatic stress symptoms
SRD5A2 gene variations affect PTSD symptoms differently in males and females.
research Minoxidil Acts as an Antiandrogen: A Study of 5α-reductase Type 2 Gene Expression in a Human Keratinocyte Cell Line.
Minoxidil may help treat hair loss by reducing the activity of a specific enzyme linked to baldness.
research Testosterone 5.ALPHA.-Reductase Inhibitory Active Constituents of Piper nigrum Leaf
Black pepper leaf extract contains compounds that can block testosterone effects and promote hair growth.
research Leydig Cell Hyperplasia and Adenomas in Mice Treated with Finasteride, a 5α-Reductase Inhibitor: A Possible Mechanism
High doses of finasteride cause cell growth and tumors in mice.
research Sexual dimorphism of growth plate prehypertrophic and hypertrophic chondrocytes in response to testosterone requires metabolism to dihydrotestosterone (DHT) by steroid 5‐alpha reductase type 1
Male cells need DHT to respond to testosterone, while female cells do not.
research Abietic Acid from Resina Pini of Pinus Species as a Testosterone 5.ALPHA.-Reductase Inhibitor
Abietic acid from pine resin can effectively inhibit testosterone 5α-reductase.
research Dutasteride, a novel dual 5-A reductase inhibitor, reduces serum DHT to a greater extent versus finasteride and achieves finasteride maximal reduction in a larger proportion of patients
