Abstract

Objective To report the birth and normal pediatric follow-up of the first baby born after transfer of embryos derived from cryopreserved rescue intracytoplasmic sperm injection (ICSI). Design Case report. Setting Academic fertility unit. Patient(s) A 36-year-old woman with unexplained infertility. Intervention(s) Reinsemination by ICSI (“rescue” ICSI) followed by cryopreservation at the pronuclear stage was performed after partial fertilization failure. Main outcome measure(s) Pregnancy, birth, and 1-year follow-up of the baby born after the transfer of the cryopreserved rescue ICSI embryos. Result(s) and conclusion(s) Zygotes obtained after rescue ICSI were able to tolerate the process of cryopreservation and resulted in a viable pregnancy and delivery.
