Effects of Finasteride, a Type 2 5-Alpha Reductase Inhibitor, on Fetal Development in the Rhesus Monkey (Macaca Mulatta)

Finasteride's effectiveness and side effects may vary based on male phenotypes, with some users noting differences in response related to body and facial hair characteristics. Some users report success with lower doses, while others experience side effects, suggesting individual variability in response to the treatment.

Dutasteride may affect semen parameters but not significantly enough to impact fertility unless baseline fertility is already low. Finasteride and minoxidil are used for hair regrowth, with no side effects reported by one user.

A 17-year-old is using oral dutasteride, finasteride, and topical minoxidil for hair loss, with plans to increase dutasteride and consider surgery. They report significant regrowth but are worried about side effects and the effects of blocking DHT at a young age.

A 24-year-old male experienced side effects like low libido and ED after starting finasteride post-hair transplant and is seeking alternatives to reduce scalp DHT. Suggestions include topical finasteride, Xpecia, DHT-reducing shampoos, and switching to dutasteride, with some users reporting fewer side effects with these alternatives.

Dutasteride may cause chronic infertility by reducing semen volume and motility, with concerns about irreversible prostate fibrosis. Users consider switching to finasteride or using treatments like minoxidil and microneedling, weighing hair preservation against fertility.

The user experienced successful hair regrowth with Finasteride and Minoxidil but developed erectile dysfunction and abdominal pain, possibly due to medication or lifestyle changes. They plan to consult a urologist and consider adjusting medication or trying supplements like zinc, DIM, or boron.
