Impact of health insurance coverage for assisted reproductive technology on multiple embryo transfers and multiple pregnancies in Japan
In 2022, the MET rate significantly decreased from 2021, whereas the multiple pregnancy rate remained similar. However, the absolute number of multiple pregnancies increased to the level before the single embryo transfer guideline, and the proportion of blastocyst transfers in MET also increased. Continuous monitoring is necessary to capture trends in the number of multiple pregnancies following ART in Japan.
