Management of multiple conceptions after gonadotropin-releasing hormone analog/human menopausal gonadotropin/human chorionic gonadotropin therapy.

The treatment course of a 31-year-old infertility patient due to PCO disease is presented. Because the patient failed to conceive after various treatment cycles with CC, she was subjected to a combined GnRHa/hMG/hCG therapy. After plasma E2 levels had reached 2400 pg/ml, three leading follicles, with diameters of 20 to 24 mm, were detected. Induction of ovulation was achieved by 10,000 IU hCG. The patient conceived and developed ovarian hyperstimulation. At 8 weeks of gestation, seven cystic structures were detected within the uterine cavity, five containing single embryos, and two with twin embryos. All nine embryos were vital, as evidenced by their heart beats. Embryo reduction was achieved by transabdominal puncture on three occasions. The three surviving fetuses were carried to the 34th week of gestation. After delivery by cesarean section, three healthy babies developed normally. This communication illustrates the complications that can be associated with ovulation induction in PCO disease: ovarian hyperstimulation, polyovulation, multiple conceptions, and their clinical management.
