A Successful Live Birth From a Vitrified Oocyte for Fertility Preservation of a Patient With Borderline Ovarian Tumor Undergoing Bilateral Ovarian Surgery: A Case Report
This article reports the live birth of a healthy newborn using vitrified-warmed oocytes from fertility preservation before ovarian surgery. The patient in our case underwent two cycles of controlled ovarian stimulation before laparoscopic bilateral ovarian cystectomy for endometriosis, and a total of 23 mature oocytes were vitrified. After surgery, her pathologic reports revealed a serous borderline tumor and endometrioma. Fifteen months after her second surgery of laparoscopic right salpingo-oophorectomy and left ovarian cystectomy owing to recurrence, she had been married by then, and three of the frozen oocytes were thawed for intracytoplasmic sperm injection. These oocytes were cryopreserved for 2.5 years. All three were fertilized, and two grade-A cleavage-stage embryos were transferred. A singleton pregnancy was achieved, resulting in the delivery of a healthy baby boy at 39.3 weeks of gestation. Oocyte cryopreservation is an effective method for fertility preservation prior to ovarian surgery when ovarian function decline is predictable.
