Abstract
In this report, we present a case of a couple who obtained a live birth with a single oocyte fertilized by ICSI. Two oocytes were collected at 35.5 hours (h) post trigger and both were at metaphase II when sperm injection was performed (38 h). At 18 h post injection, one oocyte was fertilized, developed to the blastocyst stage and underwent to trophectoderm biopsy for preimplantation genetic testing on day 5. Following biopsy, the blastocyst was vitrified and 4 h after warming procedure, the euploid blastocyst was replaced to the uterine cavity. Healthy live birth was obtained after 39 weeks of gestation.
