Objective: To present a live birth after freezing and thawing of biopsied oocytes.
Design: Case report.
Setting: Artificial reproduction unit of a university hospital.
Patient(s): A primary infertile couple with asthenoteratozoospermia and repeated failures of intracytoplasmic sperm injection (ICSI).
Intervention(s): Screening of aneuploidy during the fourth ICSI cycle with polar body biopsy (PB) for repeated failures of artificial reproductive techniques and a transfer of a cryopreserved day 2 embryo derived from cryopreserved zygotes with slow-rate freezing after PB.
Main outcomes measure(s): Live birth, viability, and survival.
Result(s): A successful pregnancy and a live birth were presented after a transfer of day 2 embryos derived from oocytes that underwent PB and subsequent cryopreservation.
Conclusion(s): Pregnancy can be obtained subsequent to cryopreservation and thawing after PB.
