PURPOSE: To estimate frozen zygotes, which developed from in vitro matured oocytes retrieved from polycystic ovarian syndrome-like disease.
METHODS: Oocyte retrieval was performed on Day 15 following withdrawal bleeding. The oocytes were incubated for 24 h in TCM-199 maturation medium supplemented with follicle fluid, E2, FSH, and hCG.
RESULTS: A total of 12 immature oocytes were collected. Seven of the 12 oocytes (58.3%) developed to the metaphase-II stage, and subsequently, all seven fertilized oocytes were frozen at the pronuclear stage. The remaining five oocytes failed to develop to the metaphase-II stage after an additional 24 h of incubation. Three of seven cryopreserved oocytes were thawed and developed to 2-8-cell cleaved stage embryos. The first pregnancy failed. However, the second frozen-thawed embryo transfer resulted in the delivery of healthy twins.
CONCLUSIONS: Successful delivery using frozen zygotes from an anovulatory woman with polycystic ovarian syndrome-like disease.
