Assisted reproductive technology (ART) has been so widely deployed across the world that over 1% of all births are now ART babies, with even higher percentages in the Nordic countries. As pregnancy rates are limited by technical, population, and inherent limitations of human reproduction, key performance indicators should be defined for all the different facets of ART to measure the efficacy of the procedure.

介绍

辅助生殖技术 (ART) 在世界范围内得到了如此广泛的部署，现在超过 1% 的新生儿是 ART 婴儿，在北欧国家的比例甚至更高。由于妊娠率受到技术、人口和人类生殖的内在局限性的限制，因此应为 ART 的所有不同方面定义关键性能指标，以衡量程序的有效性。
