Propecia and Oral Sex

Hi Dr, I was reading a number of your responses to the queries posted here and was really pleasantly surprised by the straight ahead and honest answers you provide.

I have a query related to what precautions should be taken in one’s sex life when taking propecia, apart from avoiding potential pregnancy. Could the drug be potentially damaging to a man’s partner otherwise? ie during regular sexual intercourse? or, for instance, in oral sex?

I realize these questions may sound ridiculous to someone more informed in the actual working of the drug, but there is a certain amount of vagueness surrounding these issues with propecia that I think a lot of people would like to have clarified.

many thanks. all the best

It’s not ridiculous to ask questions. If a pregnant woman gives oral sex to a man that has been taking Propecia, I would doubt that there was any side effect possible with this related to the drug (the same goes for sexual intercourse). Have fun and you can even return the favor, as there is no risk the other way around either.

For further confirmation, you can refer to a statement from the drug’s manufacturer (Merck) that I published a couple years ago related to this very topic — Propecia’s Effect on Sperm and Pregnancy.
