Brief Summary

The purpose of this study is to determine whether a policy of elective single embryo transfer (eSET) plus single embryo cryotransfer is as effective as a double embryo transfer in terms of clinical pregnancy rate

Outcome Measures

Primary Outcomes (1)

  • Clinical Pregnancy Rate

    A clinical pregnancy was defined by the presence of a gestational sac with heartbeat on transvaginal ultrasonography at the 7th weeks of pregnancy

    Seven weeks after embryo transfer

Secondary Outcomes (1)

  • Multiple Pregnancy Rate

    Seven weeks after embryo transfer

Other Outcomes (1)

  • Live Birth Delivery Rate

    38 weeks after embryo transfer

Study Arms (2)

Elective single embryo transfer

EXPERIMENTAL

After the FIV/ICSI procedure, in this arm the embryo transfer would be of a single embryo followed by the cryotransfer or a single embryo in case of no fresh conception

Procedure: Elective single embryo transfer

Double embryo transfer

ACTIVE COMPARATOR

After the FIV/ICSI procedure, in this arm the embryo transfer woub be of two fresh embryos

Procedure: Double embryo transfer

Interventions

After the FIV/ICSI procedure, the embryo transfer in this arm would be of one embryo followed by the cryotransfer of one embryo in case of no conception in the fresh cycle.

Elective single embryo transfer

After the FIV/ICSI procedure, the embryo transfer in this arm would be of two fresh embryos

Double embryo transfer

Limitations and Caveats

Our study could have been complemented by improved embryo selection, using a time-lapse system. Another limitation of our study is that after devitrification, blastocyst culture was not performed.
