Is there a problem if my wife gets pregnant while I’m taking Finasteride?
No. Originally Merck decided to err on the side of caution and warned against the possible problem of finasteride transfer in semen. This warning has since been removed. At issue is the theoretical danger that there could be genital birth defects in the male fetus. However, women who are or could get pregnant should avoid finasteride ingestion and the handling of broken finasteride tablets.
