Propecia and Infertility

Hello Mr Rassman.
I have found your web site and by the way , I find it really useful. I would like your opinion on one specific point. I have now been on propecia since February 2005 .

My partner and I have been trying to conceived since 10 month without any result . I did a sperm test wich showed a problem with living spermatozoon after 4/6 hours and a decreased (not huge but right on the limit) in the volume of semen being produced …. Can you tell me if other studies have recently been made on the effect of the finasteride on young male fertility ?

Thanks and best regards

I have written to Merck concerning this question and they have a good history showing a wide safety margin for male fertility. I looked up some sites for you with case reports that focus on your question. What it means is anybody’s guess, but I believe this is where you and your doctor come into play:

• Finasteride-associated male infertility
• Preventive Medicine and Male Factor Infertility: Facts & Fiction
• Finasteride (Propecia/Proscar) and Pregnancy
• Propecia, Infertility Link Suspected
