I am one of the most pro-adoption people out there, being that I am adopted but, adoption and fertility treatments should not be lumped together the way they often are. They are two separate issues. If a family decides adoption isn't for them, and even I can see why they would, then IVF is a reasonable idea. I do think there would need to be real common sense limits to IVF if we're paying for it, like not doing it past a certain age, if someone already has children, not implanting too many, etc.
It may interest some of you to know our Medical system in California pays for IVF under certain circumstances. The only real problem I have with it is if you can't afford IVF and you can't afford to buy your own insurance, how in the world are you going to afford a child? IVF also increases your chances of having multiples which increases your chances of having complications which increases your chances of having either mom or baby needing a long, expensive hospital stay. I don't complain about it much because it keeps me employed, but I can see why some people consider it a place where money should be saved, not spent.
