TRIPLET PREGNANCY AFTER INTRACYTOPLASMIC SPERM INJECTION OF CRYOPRESERVED OOCYTES - CASE-REPORT

Objective: To report a triplet pregnancy that occurred after intracyto plasmic injection of sperm into cryopreserved oocytes. Design: Case re port. Setting: Institute de Ginecologia y Fertilidad (LFER), Buenos Ai res, Argentina. Patient: A 36-year-old infertile patient with prematur e ovarian failure and a previous term pregnancy with fresh donated ooc ytes. Intervention(s): We administered leuprolide acetate for pituitar y down-regulation followed by E-2 valerianate in incremental doses unt il an endometrial lining of >8 mm was observed by ultrasound. Thawing of frozen donated oocytes, intracytoplasmic sperm injection (ICSI), an d translaparoscopic fallopian tube ET also were performed. Natural mic ronized 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 microinje ction into cryopreserved oocytes. Conclusion(s): This case illustrates the feasibility of oocyte cryopresentation for clinical use in the er a of ICSI. (Fertil Sterile 1998;70:360-1.
