research DHT and E2 synthesis-related proteins and receptors expression in male yak skin during different hair follicle stages
Male yak hair growth is influenced by DHT synthesis, which is promoted by 5α-red1 and AR during growth phases, while E2 may inhibit growth through ERα.
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 Expression of E-SOD, GPX5 mRNAs and immunoexpression of Cu/ZnSOD in epididymal epithelial cells of finasteride-treated rats
Finasteride changes antioxidant enzyme expression, possibly affecting sperm protection in rats.
research Connexin 43 expression in the testes during postnatal development of finasteride-treated male rat offspring
Finasteride treatment changes Cx43 in rat testes, possibly causing fertility issues.
research Paternal Finasteride Treatment Can Influence the Testicular Transcriptome Profile of Male Offspring—Preliminary Study
Father's finasteride use may affect son's fertility and testicular function.

5 / 1000+ resultscommunity 5 month comparison after switching to dutasteride
The user's progress after using dutasteride for hair loss treatment, and how minoxidil is also a helpful part of this process which can take up to one year to see full effects.
community Finasteride affects both 5a reductase and 5b reductase
Finasteride not only inactivates the 5a reductase enzyme but also affects the 5b reductase enzyme in a dose-dependent manner, which can impact sexual behavior and brain activity. The user experienced significant hair regrowth and side effects on 1mg of finasteride, which diminished after reducing the dose to 0.5mg, leading to no side effects and further hair improvement.
community UPDATE - 7 months 2,5 dutatesteride
The user continues to experience hair loss despite using dutasteride 2.5mg, minoxidil 5mg, and ciclopirox shampoo, and plans to reassess after one year. Others report similar issues with dutasteride, with some switching to finasteride or adding RU58841.
community From the research study: "Dihydrotestosterone and the concept of 5a-reductase inhibition in human benign prostatic hyperplasia" - G. Bartsch, R.S. Rittmaster, H. Klocker (2002) in the "World Journal of Urology".
Dutasteride is a stronger 5AR inhibitor than finasteride and can significantly lower DHT levels. Reduced doses of dutasteride may lower side effects.
community 7 months of Dutasteride 1mg daily and 2.5-5mg oral minoxidil daily on Diffused Unpatterned Alopecia
A user shared their 7-month progress using 1mg daily Dutasteride and 2.5-5mg daily oral Minoxidil for diffuse unpatterned alopecia, showing significant hair regrowth with reduced shedding and no side effects. They experienced a severe initial shed but now have visual improvement, despite hair still being thinner than before.
