Update on selective reduction.

Over the past 25 years fetal reduction has been utilized to reduce the risks of higher-order multiple pregnancies that have resulted from overly successful infertility therapies. The demographics of multiple pregnancy patients have evolved over the past decade, with increasing proportions coming from IVF as opposed to ovulation induction, being older and a higher proportion with donor eggs. Genetic diagnosis prior to reduction is becoming more common and is very safe in experienced hands. For all starting numbers, including twins, reduction to a lower number of fetuses reduces fetal losses, prematurity, and infant mortality and morbidity.

Do reduced multiples do better?

Dramatic successes in infertility care have allowed millions of previously fertile women to have their own children. However, an epidemic of multiple pregnancies has resulted, with catastrophic increases in morbidity and mortality, and in the economic costs to society. Multifetal pregnancy reduction (MFPR) has been used to decrease fetal number in the late first trimester and has dramatically improved outcomes. Recent data suggest that pregnancies starting with three or four, and in some cases five fetuses, which are reduced to twins, do as well as starting with twins. Patients with triplets do better reduced to twins. Reduction to a singleton is becoming more common, particularly for women over 40. Combining MFPR with chorionic villus sampling in patients over 30 years of age has enabled couples to maximize the health of the resultant children.
