Triplet pregnancy after intracytoplasmic sperm injection of cryopreserved oocytes: case report.

OBJECTIVE

To report a triplet pregnancy that occurred after intracytoplasmic injection of sperm into cryopreserved oocytes.

DESIGN

Case report.

SETTING

Instituto de Ginecología y Fertilidad (IFER), Buenos Aires, Argentina.

PATIENT: A 36-year-old infertile patient with premature ovarian failure and a previous term pregnancy with fresh donated oocytes.

INTERVENTION(S): We administered leuprolide acetate for pituitary down-regulation followed by E2 valerianate in incremental doses until an endometrial lining of >8 mm was observed by ultrasound. Thawing of frozen donated oocytes, intracytoplasmic sperm injection (ICSI), and translaparoscopic fallopian tube ET also were performed. Natural micronized progesterone was administered intravaginally (600 mg/d) before ET.

MAIN OUTCOME MEASURE(S): Ultrasound at the 8th week of gestation revealed a triplet pregnancy with active fetal heartbeats.

RESULT(S): A triple intrauterine gestation was achieved with the use of microinjection into cryopreserved oocytes.

CONCLUSION(S): This case illustrates the feasibility of oocyte cryopreservation for clinical use in the era of ICSI.
