I do often hear the increased risk argument. The first problem I think of with that is my cousin, who had endometriosis pretty bad, had an increased risk of spontaneous abortion. She's young, married, otherwise heathy, and Mormon. Having a kid was paramount to her. Should other people have the power to say that she doesn't have the right to get preggos just b/c she has a higher risk of aborting than a 100% healthy woman? That doesn't seem right...
