Four beginning pregnancies after cycles with ovarian stimulation are described. Due to a delay of implantation no rescue of the corpus luteum occurred. At first the cycles ended with menstruation, negative serum hCG and normal low serum steroid hormone concentrations. A new stimulation was started and subsequently terminated as soon as the pregnancies were detected. There was no progesterone production in all these four cases during the first 9-13 days of pregnancy. Induced by the renewed stimulation new follicular development was noticed in three patients, followed by ovulation during pregnancy. Two clinical pregnancies were the result, one with good further evolution and delivery, and one aborted at 10 weeks after the first menstrual period. The other two pregnancies ended with preclinical abortions.
本文描述了4例在卵巢刺激周期后开始的妊娠情况。由于着床延迟，未发生黄体挽救。起初，这些周期以月经结束，血清hCG呈阴性，血清类固醇激素浓度正常且较低。在检测到妊娠后，立即开始新的刺激并随后终止。在这4例妊娠的前9 - 13天内均未产生孕酮。在重新刺激的诱导下，3例患者出现了新的卵泡发育，随后在孕期发生排卵。结果有2例临床妊娠，其中1例妊娠进展良好并分娩，另1例在首次月经后10周流产。另外2例妊娠以临床前流产告终。
