Reversibility of 5-Alpha Reductase Inhibitor Effects on Semen Parameters: A Review of Human Evidence

Dutasteride treatment may decrease sperm concentration, but levels remain above WHO recommendations and recover after discontinuation. The study has limitations, including small sample size and lack of pre-treatment sperm data, and does not assess other fertility factors.

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.

Dutasteride can significantly reduce sperm volume, with some users experiencing up to a 90% decrease. While some users report adaptation over time, others suggest switching to finasteride if side effects are too severe.

A user experienced sexual side effects, including reduced semen production and numbness, after switching from finasteride to dutasteride for hair loss. They decided to stop dutasteride to prioritize their sexual health and may return to finasteride if issues resolve.

Long-term use of dutasteride may impair semen volume and sperm motility, but these effects are often reversible after stopping the drug. Individual reactions vary, and more research is needed to understand the long-term impact on fertility.

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.
