Three cases of combined pregnancy are described after gonadotropin therapy; two cases after human pituitary gonadotropin and one after human menopausal gonadotropin administration. In each case the intrauterine gestation was a multiple pregnancy. After salpingectomy, two of the women have proceeded to the delivery of healthy infants; the third woman aborted. In each case the gonadotropin stimulation regimen was ceased at the appropriate stage when the estriol excretion was between 60 and 125 micrograms/day, but the subsequent rate of rise of estriol was 2.3- to 3.2-fold during the coasting phase before the human chorionic gonadotropin trigger when the estriol excretion rate was 140 to 350 micrograms/day.
本文描述了3例促性腺激素治疗后合并妊娠的病例；2例使用人垂体促性腺激素，1例使用人绝经期促性腺激素。每例子宫内妊娠均为多胎妊娠。输卵管切除术后，其中2名女性顺利产下健康婴儿；第三名女性流产。在每例中，当雌三醇排泄量在60至125微克/天时，在适当阶段停止促性腺激素刺激方案，但在人绒毛膜促性腺激素触发前的平台期，当雌三醇排泄率为140至350微克/天时，雌三醇随后的上升速率为2.3至3.2倍。
