many people for whom this is an issue are those who WANT a child after age 35. And I would bet you that over 35s are not high in the unwanted pregnancy category.

If a woman over 35 is using any sort of birth control, and she probably is, insurance or not, then the probablility of what you fear is the probability of pregnancy TIMES the probability of a genetic problem. That gets to be a rather small number.

The issue for over 35s is whether to do amnio, and whether to abort if they don't like what's coming. Those who WANT another child are not in the discussion, because they don't want to avoid pregnancy.

The rest, who don't want to get pregnant, are likely to cover their own birth control IF their insurance doesn't.

I'm OK about an insurance company, or the government, covering birth control for all women, but if a substantial number of payers object, and insurers back off, I'm OK with that too.

I still say that you do not have a case for saying that insuring birth control is a general health issue for women, or that it is also a manifest concern for society.
