Infertility stemming from abortion is so rare these days that it is not a concern enough for doctors to remind their patients of the slight risk.
You need not answer this here if you don't want to, but did you have your abortion after the first trimester? Abortions after 12 weeks are more prone to end in infection, and I think the rate of infection in first trimester abortions is less than one percent.
Regardless, i'm sorry you had a less-than-fulfilling experience with this. I don't think it's a bad thing to make women aware of the possibility of something like this, but I hope masses of women set on abortion don't go off and change their minds and have kids they don't want in fear of the small possibility of infertility.
