Abstract

Objective: To report pregnancy and live birth resulting from intracytoplasmic sperm injection of ex vivo-retrieved mature oocytes from a woman with bilateral ovarian carcinoma.

Design: Case report.

Setting: Fertility clinic.

Patient: A 34-year-old nulliparous woman with bilateral ovarian tumor, with a risk of malignancy of 96.1% according to International Ovarian Tumor Analysis Group recommendations for adnexal tumors, who desired fertility preservation before definitive surgical treatment.

Intervention(s): Cryopreservation of ex vivo-retrieved mature metaphase II oocytes is followed by fertilization with donor sperm and embryo transfer to a gestational carrier.

Main outcome measure(s): Fertility preservation.

Results: After controlled ovarian stimulation, 12 metaphase II oocytes were retrieved from oophorectomized specimens and vitrified. Intracytoplasmic sperm injection with donor sperm was performed in remission, resulting in 9 cleavage-stage embryos, 2 of which were transferred to a gestational carrier, resulting in a normal, healthy singleton pregnancy, and the live birth of a healthy infant.

Conclusion(s): Ex vivo oocyte retrieval after oophorectomy may be a safe alternative to standard oocyte retrieval for fertility preservation in women with ovarian malignancies.

Keywords: Fertility preservation; egg freezing; ex vivo mature oocytes retrieval; oncofertility; ovarian cancer.
