Finasteride and pregnancy, is it safe?

I was hoping to get your thoughts on an issue related to the use of finasteride while trying to conceive.

There is no clear evidence that taking finasteride will cause problems at conception or with pregnancy.  What I have told my patients that asked, if they were concerned, then could go off finasteride for one week before and one week after ovulation.  Two weeks off, on a temporary basis, should not be a problem.  As I have not seen lawsuits against Merck for baby problems that are proportional to the millions of men who have taken finasteride and gotten their wives pregnant without stopping the drug, I think that it might be safe; however, I would go to Mercks (original manufacturer for Propecia) and look up on the Propecia website, advice on pregnancy and finasteride.  Keep in mind, that much of what they say was likely written by their legal department to protect them.
