Counseling for treatment of infertility should include a discussion of the risks of multifetal pregnancy, multifetal pregnancy reduction should be discussed with patients before the initiations of any treatment that could increase the risk of multifetal pregnancy. In almost all cases, it is preferable to terminate an ovulation induction cycle ...

The impact of infertility treatments on the frequency of multiple pregnancies in France was investigated using data on total multiple deliveries and multiple deliveries from assisted reproduction and intrauterine insemination (IUI) between 1994 and 2004, and by making assumptions about the expected rate of natural multiple deliveries. During this period, ...

Kao Sheng-Po - - 2006
Due to a surge in the availability of assisted reproductive techniques (ART), the incidence of multiple pregnancies is increasing. Preterm labor is a major complication in such pregnancies. Preterm delivery of the first fetus is often followed by delivery of the remaining fetuses. However, conservative management and delayed interval delivery ...

Fetal Reduction has been employed over the past two decades as a mechanism to reduce the morbidity and mortality of multiple pregnancies. Utilization of the procedure has increased dramatically as IVF has become commonplace but the average starting number has decreased with the transfer of fewer embryos. Success rates from ...
Evans Mark I - - 2005
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.
