THE EXPERIENCE OF REDUCING THE INDEX OF MULTIPLE PREGNANCIES IN THE IVF AND ICSI PROGRAMS

Abstract

The article presents the experience of the ART clinic in reducing the index of multiple pregnancy after the IVF, the IVF + ICSI programs. The decrease in the share of cycles with two embryos transfer on the 2 and 3 days of development and increasing in the share of cycles with one blastocyst transfer led to decrease of the multiple pregnancies rate in the clinic from 29% in 2006 to 6% in 2017. It is shown that one blastocyst transfer reduces the multiple pregnancy rate without a significant reduction in the overall clinical pregnancy rate. With reference to the performed analysis the algorithm of selecting of the day of embryo transfer and the number of embryos transferred embryos was developed.
