Summary

In traditional assisted reproductive technology (ART), choosing multiple embryo transfer to get a high clinical pregnancy rate while increasing the risk of multiple pregnancies. Research showed that the single-cleavage embryo transfer could not simultaneously meet the dual requirements of maintaining pregnancy rate and reducing the multiple pregnancy rate.The purpose of this study was to observe the clinical outcome between double cleavage embryo transfers and single blastocyst transfers in fresh cycle through RCT study with GnRH antagonist protocol.

Conditions

  • Infertility, Female

Interventions

PROCEDURE

double cleavage-stage or single blastocyst stage embryos transfer
