Over the past decade, significant endeavors have been directed toward establishing an optimal oocyte number to maximize the chances for successful in vitro fertilization outcomes. The effectiveness of assisted reproductive technologies has greatly improved, and more good-quality embryos are being created in each cycle. However, many of these embryos remain unused. Notably, in Europe, approximately one-third of couples did not use their surplus cryopreserved embryos. Surplus embryos pose a challenge for patients and clinics. Embryo disposal practices are not the same all over the continent, with embryo donation and embryo discharge not allowed in several countries. In this scenario, limiting the number of surplus embryos by reducing the number of inseminated oocytes, according to couple clinical history, could be a strategy.
在过去的十年中，人们做出了巨大的努力来确定最佳的卵母细胞数量，以最大限度地提高体外受精的成功率。辅助生殖技术的有效性有了很大的提高，每个周期都能产生更多的优质胚胎。然而，其中许多胚胎仍然未被使用。值得注意的是，在欧洲，大约有三分之一的夫妇没有使用他们多余的冷冻胚胎。多余的胚胎对患者和诊所来说都是一个挑战。胚胎处理方式在整个欧洲大陆并不相同，一些国家不允许胚胎捐赠和胚胎丢弃。在这种情况下，根据夫妇的临床病史，通过减少授精卵母细胞的数量来限制多余胚胎的数量可能是一种策略。
