Does taking Propecia affect the child in the mother's stomach, as in birth defects? Alternatives to Propecia?

I read a similar question, as I made sure to look this up before posting this question. However, I was hoping for a definitive response to this.

I'm about to turn 31 and I noticed that my hair is starting to thin in the back of my head (the crown area). I remember my ex-girlfriend telling me she "heard" that if the male was taking Propecia and he impregnates the girl, the baby will have birth-defects. Is this true? Is it documented? I'd obviously not flirt with the chance of having a child with birth defects, so I'll hold off on taking it. But I was also wondering if there were any alternatives to Propecia or Rogaine that's harmless for conception and is proven to work. Any help would be appreciated.

Thanks to the two responses I've received so far. I guess, specifically, I want to know if the Propecia is carried in the sperm. And if you ejaculate in the female, will the Propecia affect the sperm so that when it combines with the egg, the baby has the effects of the Propecia -- which, in turn, results into a birth defect? I wish I could explain in better. Basically, I don't want to be taking Propecia if having a kid with a girl will result in the child having a birth defect based on the Propecia. (Thanks for the responses so far, and looking for more!) :)

Propecia is NOT for use by women. If taken during pregnancy, it can cause abnormal development of a male baby's genital organs.But I don't think that there is any reason the man couldn't take it. I would check with a doctor to be sure.If the woman was taking it ...that would definitely be a problem but not the father.
