Propecia and Fertility

Propecia and fertilityQ:

I am a man with male patterned hair loss and I have been using Propecia for 2 years now.  My wife and I are planning to have children.  What are the effects of Propecia on fertility?  Can it affect the unborn child?

Thanks,

A:

Propecia (finasteride) can reduce the volume of semen slightly in 1% of the patients, but it does not affect the sperm count or chances of fertility.  Nor does the use of finasteride in men decrease the chance of pregnancy in their partners.

Propecia can be secreted through all body fluids, including semen, but its amount in semen is very minimal.  The amount that is absorbed into the mother’s body is so minimal that its risk to the baby is considered negligible.  Thus, it is not recommended for men to discontinue Propecia when their wives are pregnant, or trying to get pregnant.
