摘要
短效促性腺激素释放激素激动剂(GnRH—a)长方案仍然是目前体外受精一胚胎移植(IVF—ET)助孕治疗中的“金标准”方案。自1984年GnRH—a应用于IVF领域后,已有大量研究证实了其有效性。与单纯促性腺激素(Gn)促排卵比较,GnRH—a长方案能有效抑制早发内源性黄体生成素(LH)峰,减少取消周期,改善卵泡同步化,增加获卵数,提高卵母细胞和胚胎质量,改善子宫内膜接受性,提高妊娠率等优点,但伴随的缺点是增加Gn量,延长治疗时间,增加卵巢过度刺激综合征(OHSS)风险,
The short-acting GnRH agonist long protocol is still a standard protocol in IVF. The down-regulation mode of short-acting GnRH agonist long protocol mainly includes two aspects:firstly,it requires at least 14 days of down-regulation of GnRH agonist for complete suppression of estradiol prior to ovarian stimulation; secondly, the antral follicle counts may change during down-regulation. Therefore, down-regulation of GnRH agonist long protocol needs at least 14 days; and appropriate prolongation of short-acting GnRH agonist down-regulation could improve the synchronization of follicular development.
