I would have to say it depends on circumstances. Personally, I abhor abortion on demand (i.e. abortion as a method of birth control), but there are circumstances where the life of the mother is in serious jeopardy, and I don't mean "psychological health," which is a loophole used by the planned parenthood types. I mean serious medical complications where the mother would die without an abortion. Under those circumstances, I would leave it up to the mother to decide if she wants an abortion to save her life or if she is willing to risk going to her grave with her unborn baby. Under those specific circumstances and complications, her ob-gyn should either perform the abortion or refer her to someone who can do it and not, through his or her own 'moral convictions' sentence the mother to death. If the ob-gyn can't, then perhaps another line of work is in order.
Perhaps someone more familiar with ob-gyn's in this thread can answer this question. To be an ob-gyn don't you need learn how to perform an abortion in medical school?
Yes, I believe that a part of the OB-GYN curriculum is about abortion. AT least in the programs I am familiar with. There are times (I cannot tell you how many or what percentage) that a woman's life is in jeopardy and aborting the fetus is the only way to save the mother. The fetus wouldn't survive without the mother being alive. I know 2 OB-GYNs personally and both have aborted fetuses to protect the mothers life. Both are pro-life. (In both cases the mother suffered from HELLP, which can cause severe kidney damage, hypertension and greatly increases the likelyhood of a stroke)
