Propecia and birth defects

[pharmacy7424]

Scenario:

Man is taking propecia for baldness. Man impregnates woman. Is there a higher chance of birth defects because the finasteride was present in the semen that fertilized the egg?

What about if the man starts propecia after the woman is already pregnant, and they have unprotected sex in which the man ejaculates inside the vagina. Does the finasteride-containing semen pose a risk to the fetus?

Know what post a risk to the fetus? Being bald in his 20s

Explain.

Explain.

Humor is not your area of strength it seems.

I did not know that propecia is excreted into the semen. If anyone knows more about this subject, please enlighten me. I am curious as well.

Wow you guys really need more to do with your time.

The point is that it might be prudent to counsel a man that if he is sexually active he may want to consider contraceptive if the risk of birth defects is not yet established.

Read the package insert: http://www.merck.com/product/usa/pi_circulars/p/propecia/propecia_pi.pdf

It seems the answer is that it's probably okay, since the animal tests showed no abnormalities in male fetuses at blood concentrations in the pregnant females 930x higher than what they would get from exposure to the semen of a male taking finasteride 1 mg/day.

If OP is a Rph can't he/she just do their own research to find the answer instead of going to SDN?

OP has started a bunch of weird threads lately...

Hi,

I've joined this group to comment on this, as I've been taking finasteride, Propecia for about 9 years. My wife got pregnant for the first time about 3 years ago. I took propecia as normal throughout the pregnancy. In one of the fetal scans we discovered that our baby "a girl" had Achondroplasia (dwarfism). It was never determined why that happened. The doctors said it was a random thing. I didn't consider the propecia until I was recently contacted by my doctor warning me that new studies showed that finasteride had been linked to male fetal abnormalities. After reading a bit on this, I see nothing that talks about dwarfism or female fetus abnormalities, so I don't know if it is relevant to the discussion. Nonetheless, it has opened a nagging doubt in my mind. I feel I should mention for the record.
