4. multiple pregnancy rate(English)

   • calculated as the percentage of pregnant women with multifetal pregnancy, defined as the detection of ≥ 2 intrauterine gestational sacs with fetal heartbeats. Higher MPR is noted in two situations: transfer of three cleavage embryos in women aged 35-39 years (66.7%) and transfer of two blastocysts in women aged ≥ 40 years. Women aged <35 years old are a high-risk group for high-order multiple pregnancy
