Permanent Problems from Propecia?

Hi Doc,
Is anything known about the permanence of the sexual side effects of Propecia? I’m concerned about serious fertility problems if I start using this drug, and I’m skeptical of Merck’s claim that all side effects go away quickly once you stop usage (how would they know? Propecia hasn’t been around that long). I’ve just been browsing comments about Propecia on the web and, from reading about various people’s experiences with it, it’s not so clear to me anymore that this drug won’t cause a permanent problem.

I’ve written a lot about Propecia on this site. Please do a search for Propecia or Propecia side effects to read my many blog entries about this. Quite simply, if you do not trust the drug company or the FDA, then you should not take the drug. In fact, do not take Propecia or any drug unless you have confidence in the information sources; in this case Merck and the FDA.
