How common in PFS?

Post Finasteride Syndrome is very uncommon. In my practice of 27 years, I have prescribed this drug on tens of thousands of men, although I did hear reports of sexual side effects in between 2-4% of these patients, I have never had a single case of PFS discussed with me. I have very good relationships with my patients and I am absolutely sure that if their sexual side effects would have persisted, I would have been part of the solution for these patients and been involved in their management of the problem.
