Committee Opinion No. 719 Summary: Multifetal Pregnancy Reduction
Although not all multifetal pregnancies occur after the use of assisted reproductive technology, fertility treatments have contributed significantly to the increase in multifetal pregnancies. In almost all cases, it is preferable to avoid the risk of higher-order multifetal pregnancy by limiting the number of embryos to be transferred or by cancelling a gonadotropin cycle when the ovarian response suggests a high risk of a multifetal pregnancy. When multifetal pregnancies do occur, incorporating the ethical framework presented in this Committee Opinion will help obstetrician–gynecologists counsel and guide patients as they make decisions regarding continuing or reducing their multifetal pregnancies.
