research Overexpression of aldo-keto reductase 1C3 (AKR1C3) in LNCaP cells diverts androgen metabolism towards testosterone resulting in resistance to the 5α-reductase inhibitor finasteride
Too much AKR1C3 enzyme causes resistance to finasteride by increasing testosterone.
research Long-term use of 5α-reductase inhibitors and the risk of male breast cancer
Taking 5α-reductase inhibitors does not significantly increase the risk of breast cancer in men.
research Synthesis and biological evaluation of novel unsaturated carboxysteroids as human 5α-reductase inhibitors: A legitimate approach
New steroid compounds effectively inhibit 5α-reductase and may treat hair loss.
research The new paradigm for androgenetic alopecia and plant-based folk remedies: 5α-reductase inhibition, reversal of secondary microinflammation and improving insulin resistance
Plant-based remedies may treat hair loss by reducing inflammation and improving insulin resistance.

5 / 194 resultscommunity 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 Did anybody use beta sisterol for hair loss? I saw in many articles in the internet that said that beta sisterol blocks dht by inhibiting 5a reductase type 2 enzyme and some reviews of people who said that it worked better than saw palmetto in terms of stoping hair loss and helping prostate.
Beta-sitosterol may inhibit 5-alpha reductase type 2 enzyme, potentially reducing DHT levels and promoting hair growth, similar to finasteride but possibly with fewer side effects. Its effectiveness and side effects compared to other treatments like saw palmetto and finasteride remain uncertain due to limited research.
community Supposedly dairy contains precursors to DHT that are already 5a-reduced and convert to DHT independent of 5a-reductase inhibition
Dairy may contain DHT precursors that could affect hair loss and prostate health, with some users noting reduced hair shedding after eliminating dairy. Individual responses to dairy and DHT blockers vary, with some attributing hair health to diet changes and others seeing no impact.
community A repository of links to current scientific research and findings into the nature of and relating to side-effects for Finasteride/Dutasteride/5a-reductase inhibitors.
Finasteride and dutasteride, used for hair loss, can cause sexual dysfunction, depression, and suicidal thoughts, with some effects persisting after stopping. The post stresses the importance of being aware of these risks.
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.
