NCT03128970

Brief Summary

The aim of the present study is to determine if implantation rate could be increased in women undergoing frozen embryo transfer cycles in case of adjusting their embryo development at hatching stage.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Ongoing implantation rate

    ultrasound detection of ongoing gestational sacs with heartbeats after 12 weeks of gestation per transferred embryos

    12 weeks

Study Arms (2)

frozen/thawed

NO INTERVENTION

blastocysts with three or less grade of expansion will be thawed and then subsequently transferred into women uterus three hours post-thawing.

synchronized frozen/thawed hatching blastocysts

EXPERIMENTAL

blastocyst thawing (with three or less grade of expansion) will take place the day before embryo transfer in order to reach hatching stage

Other: synchronizing blastocysts

Interventions

transferring frozen/thawed a synchronized blastocysts at hatching stage into female uterus.

synchronized frozen/thawed hatching blastocysts

Eligibility Criteria

  • Patients undergoing FET after their 1st IVF or ICSI cycle with no pregnancy at the fresh transfer
  • Freeze-all cycles due to OHSS
  • Freeze-all cycles due to poor endometrium
  • Age 19-33 at the time of randomization.
  • Their frozen blastocysts are 3 or less grade of expansion.
