Let's hear it for abstinence-only sex education.
The reality is, teenagers are going to have sex, no matter how often you tell them not to. So they need to be educated that, while abstinence is arguably
best, if you do not choose abstinence, you should be using a condom. (Or a diaphragm, or the pill, or something. A condom is best because it also protects against STDs.)
It's also worth noting that seven of these ten states require parental consent, and an eighth (Georgia) requires parental notification, for a minor to get an abortion. If I had been unlucky enough to become pregnant at age 15 (unlikely as I wasn't sexually active back then, and if I had been, I would have insisted on a condom), I could have walked into any abortion clinic in New York and said, "I want an abortion." But if I had lived in Mississippi, where the consent of BOTH parents is required, my uber-religious pro-life parents would have prevented me from getting an abortion. I would have had to carry the pregnancy to term and then either place the child for adoption or wave bye-bye to a college education and a career.
