We're trying to get pregnant right now and I have been on finasteride since 1997 so I asked our doc, I also asked my Endocrinlogist. The finasteride thing got blown out of proportion...EXCEPT the touching of the pills...that is accurate. They both said no real concern, but I could stop for a little while due to its half life.
This seems to be a good portion of an article from some MD on the net:
So if the woman were not exposed by powder the other way is via semen. This, too, has understandably been well studied. Again found in the PDR are the following studies: “Semen levels have been measured in 35 men taking finasteride 1 mg/day for 6 weeks. In 60% (21 of 35) of the samples, finasteride levels were undetectable (<0.2 ng/mL). The mean finasteride level was 0.26 ng/mL and the highest level measured was 1.52 ng/mL. Using the highest semen level measured and assuming 100% absorption from a 5-mL ejaculate per day, human exposure through vaginal absorption would be up to 7.6 ng per day, which is 750 times lower than the exposure from the no-effect dose for developmental abnormalities in Rhesus monkeys and 650-fold less than the dose of finasteride (5 mug) that had no effect on circulating DHT levels in men.”
