Multiple pregnancies following fertility treatments typically occur in 30% of women in whom more than one embryo is transferred. Worldwide, fewer than 20 countries have fully funded public fertility treatments, and many women utilizing assisted reproduction technologies are transferring more than one embryo for financial reasons because they consider it will be cheaper to have two embryos transferred in the one procedure. Yet, there is a large body of evidence for the poorer health, economic, and social outcomes for mother and baby from multiple pregnancies. Some countries have reduced the multiple pregnancy rate to less than 5% by linking the funding of ART to policies where the large majority of transfers are single embryos.
接受生育治疗的女性中，有 30%会出现多胎妊娠，这通常是因为移植了多个胚胎。在全球范围内，只有不到 20 个国家提供全面资助的公共生育治疗，而许多使用辅助生殖技术的女性出于经济原因会移植多个胚胎，因为她们认为在一次手术中移植两个胚胎更便宜。然而，大量证据表明，多胎妊娠会对母婴的健康、经济和社会状况产生不利影响。一些国家通过将辅助生殖技术的资金与政策挂钩，将大多数胚胎移植都限定为单胚胎，从而将多胎妊娠率降低到 5%以下。
