A successful pregnancy following recurrent implantation failure with clinical laboratory strategy

Abstract

In treatment cycles of in vitro fertilization (IVF), 15% of the oocytes are immature and in the germinal vesicle (GV) phase. In rare occasions, more than 50% of the oocytes of a patient in a cycle are immature. Selecting fertility treatment for patients in this situation can be very challeng-ing. The patient described in this report was a 35-year-old woman with primary infertility for 10 years. She had un-dergone fertility treatment six times, with no success. In her cycles, more than 50% of the oocytes were immature and in the GV phase. To address the situation, we devel-oped a coordinated protocol involving medical and embryology procedures, analyzed the patient’s medical records, and looked into the reasons of prior treatment failure. The development of a special and coordinated effort-instead of having medical and embryology teams working in isola-tion-proved efficient at providing better outcomes to the patient.
