I believe that the official stance is that it’s illegal due to Federal Law to force any medical student or resident to perform abortion. However, there are pressures.
I’ve been out for 20 years, but I hear stories about would be 0b/Gyns who can’t get a residency slot because they’re prolife. There’s at least one New York Family Practice residency program that offers a “fellowship” - extra training after finishing residency - in “reproductive medicine. Essentially, they run an abortion clinic.
Prolife faculty members have told me they make a point of mentoring students. There’s the American Association of Prolife OB/Gyns http://www.aaplog.org/ and the Christian Medical Association http://www.cmda.org/wcm/
We give students a community as well as support prolife views.
