Ultrasound: What is its effect on a woman considering an abortion?

Several states have passed laws making it tougher to get abortions. The law passed in Oklahoma caught my eye. It requires doctors to give an ultrasound exam to the woman, and explain to her the results of the exam. It seems to me that this would force a woman to think about the baby she is about to have killed. Perhaps this will encourage more women to think of adoption as an option. Of course, the law is already being challenged in a lawsuit. Maybe the ultrasound law will also encourage the Democrat party to reconsider abortion as one of its pillars. Naw, I don't think so.
