“I’ve never seen anybody who said they were coming in to an abortion, wanted to see the ultrasound, reacted to it and then changed their mind on the basis of that,” said Ellen Wiebe, an abortion provider and director of the Willow Women’s Clinic in British Columbia, Canada.

Wiebe has done some of the few studies worldwide that attempt to look at women’s reactions to viewing an ultrasound pre-abortion. The research can’t speak directly to laws like the proposed Texas bill, Wiebe told LiveScience, because in that study “nobody was ever forced to do something they didn’t want to do.” But it is the closest thing to research anyone has ever done on state sonogram policies.

The study, published in 2009 in the European Journal of Contraception and Reproductive Health Care, found that, when given the option, 72 percent of women chose to view the sonogram image. Of those, 86 percent said it was a positive experience. None changed their mind about the abortion.
