If you tell a woman that if she has an abortion, she runs a 10% risk of becoming unable to have any children in the future I think you would see a sizable number of women decide that they don't want to take that kind of risk.
Information is power, except in the case of a woman seeking an abortion I suppose.
Maybe, but given that most women seeking abortion are <25 (if I remember correctly), I wonder if they're thinking that far into the future. It might help, I don't know.
