GnRH拮抗剂方案中血清INHB变化特点及其与COH结局的相关性研究

GnRH拮抗剂方案中血清INHB变化特点及其与COH结局的相关性研究摘要：目的：本研究旨在探究GnRH拮抗剂方案中血清INHB变化特点及其与COH结局的相关性，为提高临床治疗效果提供基础数据。方法：纳入符合标准的试管婴儿患者84例，随机分为观察组（GnRH拮抗剂方案治疗）和对照组（长方案治疗），测定患者血清INHB水平，并分析其与COH结局的相关性。结果：1.观察组患者INHB平均值比对照组低；2.观察组患者回收卵子数和成熟卵子数比对照组多；3.观察组患者受孕率和妊娠率比对照组高；4.患者INHB水平与COH结局具有显著相关性。结论：GnRH拮抗剂方案对患者体内INHB水平的调节可能是通过减少早期黄体前体细胞的生成和抑制LH介导的黄体形成所致，能有效提高COH结局的成功率。
