Three stamps. The cautious one wins.
Avoid while pregnant: an FDA label, the AAD, ACOG or a peer-reviewed review advises against it. Ask your doctor first: a source says to limit it or to check with a doctor, the sources we read disagree, or we found too little to go on. Generally considered OK: every source we read that covers it says it can be used. No stamp replaces your OB-GYN.

Why it matters for a boy
Finasteride treats male-pattern hair loss and an enlarged prostate; some women take it off-label for hair loss or excess hair growth, though it isn’t FDA-approved for women. MotherToBaby says animal studies using large doses between weeks 8 and 12 of pregnancy, when the sex organs form, found genital differences in male offspring, including hypospadias.
Tablets at home and a partner’s use
As a precaution, pregnant women are advised not to handle crushed or broken tablets; MotherToBaby says the coating on whole tablets should prevent contact, and that it’s unlikely enough would pass through the skin to raise risks. Wash your hands if you do touch a broken one.
If your partner takes it, only small amounts are found in semen, and MotherToBaby says that exposure isn’t expected to be high enough to harm a pregnancy. One recent study linked a father’s use to undescended testicles in newborns, while other reports describe healthy babies.
What about breastfeeding?
Finasteride hasn’t been studied in breastfeeding, and it isn’t known whether it passes into milk. MotherToBaby notes the product label says breastfeeding women should not use it.

Can I touch my partner’s finasteride pills while pregnant?

Is it a problem if my partner takes finasteride while we try to conceive?
MotherToBaby says the small amounts in semen aren’t expected to harm a pregnancy. One study linked a father’s use to undescended testicles; ask your doctor if you’re worried.
