"This commitment to the principle that safe abortions should be available to all who seek them is a necessary corollary of Planned Parenthood’s activities in the area of birth control. While Planned Parenthood does not view abortion as an alternative to contraception, it recognizes that abortion services are essential to protect women where contraception is unavailable, where it has not been used or where it has failed. Planned Parenthood believes that abortions must also be available to women who have been raped and in cases where the fetus may be deformed as a result of the mother’s exposure to rubella, her use of drugs which affect fetal development or as a result of other factors."
