According to a recent study led by Raymond M Fertig, a Caresse Gamret, Evan Darwin and Subdeep Gaudi of the University of Miami, Miller School of medicine is shown that finasteride is effective in the treatment of benign prostatic hyperplasia and Androgenetic alopecia by substantially reducing dihydrotestosterone levels.

It has also been documented that they may increase the incidence of sexual dysfunction.
Decreased libido, ejaculation disorder, and impotence are among the drug-related adverse effects that are reported most of the times.

Erectile dysfunction or impotence has been cited as the most common side effect in multiple studies for finasteride in shots of 5 mg/day followed by decreased libido.

In the largest meta-analysis performed to date, a significantly higher risk of sexual dysfunction (156% increase) was found for men treated with Finasteride for BPH (benign prostatic hyperplasia).

Based on these findings, we recommend that physicians consider and discuss with their patients possible sexual side effects and risk of depression before selecting pharmacological treatment.
