Abstract
Objective: To describe two successful cases of utilizing refrozen blastocysts by vitrification derived from supernumerary embryos. Design: Case report. Setting: Private fertility clinic. Subjects: Two infertility couple. Interventions: Refrozen blastocysts by vitrification derived from supernumerary embryos. Main outcome measures: Obstetric and pediatric results. Results: Two pregnancies obtained from refrozen-warmed blastocysts led to two healthy babies being born without clinical or genetic problems. Conclusion: These case reports support the notion of safely repeating cryopreservation. However, despite these favorable results, there is still a need for prospective controlled studies on the obstetric and neonatal repercussions of refreezing and of vitrification in particular.
