摘要 促性腺激素释放激素拮抗剂(GnRH-ant)可与垂体GnRH受体竞争性结合,用于超促排卵中可有效阻止早发LH峰的出现。GnRH-ant的作用特点是用药初期无激发效应,用药后保留垂体对GnRH的反应性,且抑制作用呈剂量-效应相关性,上述特点可使促排卵计划更加灵活。国内外学者对GnRH-ant联合卵巢温和刺激方案进行研究发现,其与临床上常用的黄体中期降调节长方案相比,前者在不降低妊娠率、不影响卵子和胚胎质量、不增加胎儿畸形风险的基础上,还具有以下优势:减少Gn用量,降低治疗费用;降低OHSS风险;缩短治疗周期,减轻患者心理负担。因此,GnRH-ant联合卵巢温和刺激方案可作为体外受精-胚胎移植促排卵时的可靠选择。本文就GnRH-ant的作用机制和特点以及联合卵巢温和刺激在临床上的应用价值及优势进行了综述。
