ACOG Committee opinion no. 553: multifetal pregnancy reduction.

Fertility treatments have contributed significantly to the increase in multifetal pregnancies. The first approach to the problem of multifetal pregnancies should be prevention, and strategies to limit multifetal pregnancies, especially high-order multifetal pregnancies, should be practiced by all physicians who treat women for infertility. Incorporating the ethical frameworks presented in this Committee Opinion will help physicians counsel and guide patients when making decisions regarding multifetal pregnancy reduction. In cases of high-order multifetal pregnancies, counseling should include the availability of multifetal pregnancy reduction. Fellows should be knowledgeable about the medical risks of multifetal pregnancy, the possible medical benefits of multifetal pregnancy reduction, and the complex ethical issues inherent in decisions regarding the use of multifetal pregnancy reduction. Physicians should not be required to act in ways that conflict with their value systems but should be prepared to react in a professional and ethical manner to patient requests for both information and intervention.
