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 fetal reduction have improved as a function of increasing experience, better ultrasound, and lower starting numbers. Genetic diagnosis prior to reduction can improve the overall outcomes. Reduction of triplets or more clearly improves outcomes, and reduction of twins to a singleton is now a reasonable consideration.
在过去二十年中，减胎术已被用作降低多胎妊娠发病率和死亡率的一种手段。随着体外受精（IVF）变得普遍，该手术的应用急剧增加，但随着移植胚胎数量的减少，平均起始胎儿数量有所下降。随着经验的增加、超声技术的改进以及起始胎儿数量的减少，减胎术的成功率有所提高。减胎术前的基因诊断可以改善总体结果。减少三胎或更多胎儿明显改善了结果，现在将双胞胎减为单胎也是一个合理的考虑。
