Question: Abortion Trends

Some opinion polls suggest that young women's attitudes toward aboriton have become more conservative over the past ten years or so. I'm trying to find out why. I'm a freelance journalist and I want the information for a story I'm writing on menstrual extraction. I have been trying to find someone in academia who studies aboriton and could give me an opinion on this trend, but I've had no luck. I appreciate any help you can offer.
