Addressing the growing problem of multiple gestations created by assisted reproductive therapies.
Iatrogenic multiple pregnancy is the most significant complication of assisted reproductive technology (ART). Approximately half of all children born subsequent to ART result from a plural gestation. Furthermore, the majority of triplets and higher order births are the product of ART. The risks for multiple pregnancy vary with practice patterns and the techniques used to achieve pregnancy. Recognizing the potential for serious morbidity associated with multiple pregnancies, infertility specialists have developed strategies to reduce the complication of multiple pregnancies while maintaining acceptable pregnancy rates. Implementation of these refined practices has led to a reduction in the incidence of higher order multiple births, although the incidence of twins has yet to be minimized. Further reduction in the incidence of multiple births after ART necessitates a redefinition of success to emphasize the healthy singleton birth rate, rather than crude pregnancy rates.
