Persistent Sexual and Nonsexual Adverse Effects of Finasteride in Younger Men

January 2014 in “ Sexual medicine reviews ”

Michael S. Irwig

TLDR Finasteride can cause sexual problems and depression in young men.

This document discusses the persistent sexual and nonsexual adverse effects of finasteride in younger men. The study found that finasteride, a medication used to treat male pattern hair loss and benign prostatic hyperplasia, had detrimental effects on erectile function, libido, and orgasm problems. The study also found that finasteride was linked to depression in rodents and humans. The paper suggests that healthcare providers should be aware of these potential adverse effects and discuss them with patients before prescribing finasteride.
