there was one doctor who performed D&C abortions. He didn't do lot of them, but he did some. I knew one girl in my high school class who had one. She told me, but swore me to secrecy about it. I later learned that he did them only for his existing patients, and only after being persuaded to do so and with the understanding that it would not be disclosed.
Nobody ever bothered him about it. I suspect that was because his services were sometimes used by influential members of the community when their daughters "came up pregnant," as the saying went. He was never charged with a crime.
He wasn't my doctor. I didn't really know him. I did go to him once, when I was in High School, when my own doctor was out of town. He seemed like a very nice man. I was good friends with his daughter, who was one class behind me. The subject never came up, so I don't know if she was aware of it.
I suspect that such abortions were not all that rare, and that quite a few doctors in different communities provided them from time to time. But, they certainly were only available under very specific circumstances.
However, when the birth control pill became available, a year after I graduated from high school, a number of the doctors in town were prescribing them for girls' mothers, after examining their daughters. It took a while before single women under the age of 21 could have a prescription for them.
On the other hand, the health center at the college I attended paid no attention to that limitation and prescribed them to any female student who requested them. That health center, too, in 1964, had a big fish bowl full of condoms in the reception area, with a sign on it that said, "Free! Take as many as you need." That's California for you.
