This is SO important for women to know. Also, the chance of miscarriage rises to almost 50% per pregnancy by the late 30s! So even if women manage to get pregnant in their late 30s half the time they will have devastating losses. And those who think, "I'll just try fertility treatments" need to know that IUI only works about 15% of the time and IVF only works about 25-40% of the time (and the 40% figure is for women in their 20s with only tubal problems) *AND* IVF is $10K+ per attempt. It drives me nuts to see my friends cavalierly deciding to "start trying" in their mid to late 30s.
So even if women manage to get pregnant in their late 30s half the time they will have devastating lossesI can attest to this. My wife had two miscarriages before giving birth to our son. She is 36. Devastating miscarriages.
And on a side note, I know many women, liberals, who have had devastating miscarriages, who are STILL vehemently pro-choice, but, after their miscarriages, they will not debate the subject with me, because they know the question I would be asking.
