5α-Reductase Activity in the Prostate

Androsterone may help with sexual and affective dysfunction from finasteride by replacing disrupted neurosteroids without increasing androgenic side effects. Controlled testing is needed to confirm its effectiveness and safety.

Androgenic alopecia (AGA) might have evolved to reduce prostate cancer risk by increasing UV exposure to the scalp, but this theory is debated. Treatments like minoxidil and finasteride are used for AGA, though the exact causes and evolutionary reasons for hair loss are unclear.

A user experienced negative side effects, including low libido and lack of motivation, after using finasteride for hair loss and felt better after stopping it. Others shared similar experiences with finasteride and dutasteride, while some reported no side effects, showing varied individual responses.

Finasteride and dutasteride have potential risks, including post-finasteride syndrome, but are commonly used for hair loss. RU58841, minoxidil, and needling are suggested as alternatives, though all treatments carry risks.

Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.

Finasteride can reduce neuroactive steroids, causing side effects like depression, anxiety, and sexual dysfunction. Some users experience persistent symptoms after stopping finasteride, while others use alternative treatments like topical solutions.
