Finasteride and Male Infertility: A Case for Prospective Collaborative Research Databases

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 30-year-old man experienced significant hair regrowth and improved libido after using finasteride and dutasteride for androgenetic alopecia, with no adverse effects. He plans to reduce dutasteride dosage when trying to conceive and has been using topical minoxidil since 2015.

A 27-year-old male physician improved hair density using minoxidil 5% foam and finasteride 1mg every other day, with initial sexual side effects that subsided. He recommends trying finasteride for a year but warns against dutasteride due to potential liver effects.

A 30-year-old experienced mild erectile dysfunction and low libido on 1 mg finasteride, which resolved after reducing the dose to 0.5 mg, but noticed a drop in sperm count. Despite these side effects, they achieved good hair density improvement over three years without using minoxidil.

Finasteride is effective for treating male pattern baldness (MPB) with minimal side effects, and topical finasteride is similarly effective. Dutasteride is also effective but less understood, and Minoxidil is less effective than Finasteride.

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.
