- Indirect assistance, as in providing contraceptive information for unmarried patients;
- Direct assistance, as in referring a patient for surgery (such as vasectomy or abortion) that is not halachically sanctioned;
- Direct involvement in the sin, as in providing anesthesia during a surgery that is not halachically sanctioned.
After reviewing relevant halachic rulings, I think that the first tier of cases is permitted, provided that the information is available from other sources of equal quality and availability. The prohibition against causing others to stumble will not apply because other sources of quality information are readily available, and because one is not moving the actual transgression forward in any active way. Halachic sources include Rama Yoreh Deah 151:1, Ksav Sofer Yoreh Deah 83 and Tzitz Eliezer 19:33:1.
Nonetheless, I found the following position articulated at the website of the Association of Orthodox Jewish Scientists:
Question: Does halacha permit the orthodox Jewish physician to give contraceptive advice to and to prescribe contraceptive devices for unmarried girls?
Answer: Except under very exceptional circumstances, Judaism considers it immoral for the physician to give contraceptive advice to an unmarried girl.
Comment: The doctor must use judicious moral judgment in this sensitive area of human relations. Judaism deems it immoral to give contraceptive counsel to unmarried persons when such advice may serve to remove an important barrier to immoral conduct. When confronted with the mentally retarded patient or with people in whom self-discipline is lacking as determined by previous conduct, consultation with a religious guide should be undertaken to decide the proper course of action.This Halacha Bulletin was written by Fred Rosner, MD, FACP and Rabbi Moshe D. Tendler, PhD and reviewed by HaRav Moshe Feinstein, zt"l.
I wonder what drives this position.
