在过去的25年用减胎术来降低过度应用不孕症治疗技术所致的高数量的多胎妊娠的风险。近几十年多胎妊娠的人口统计学数据已经发生了如下变化:由于反对诱导排卵,导致IVF的比例增加;患者年龄偏大;使用捐赠卵子的比例增加。在行减胎术之前进行基因诊断越来越普遍,由有经验的医师来做又非常安全。对包括双胎妊娠在内的所有多胎妊娠的患者来说,减少胎儿数可以降低流产率、早产率、及胎儿死亡率和发病率。
Over the past 25 years, ART has been used to reduce the risk of high numbers of multiple pregnancies resulting from overuse of ART. The demographic data for multiple pregnancies have changed in recent decades as a result of opposition to induction of ovulation, resulting in an increased proportion of IVF; older patients; increased use of donated eggs. It is becoming more and more common to perform genetic diagnostics before line ablation, which is done by experienced physicians and is very safe. For all patients with multiple pregnancies, including twin pregnancies, reducing the number of fetuses can reduce miscarriage rates, premature birth rates, and fetal mortality and morbidity.
