font-family: 微软雅黑, Microsoft YaHei; font-weight: 600;">拮抗剂</span>方案因其高效、安全、便捷的特点,已成为三代试管婴儿促排治疗中主流的方案选择。</span></p><h4 style="font-weight: var(--ds-font-weight-strong); font-size: 16.002px; margin-top: ;

font-weight: 600;">拮抗剂</span>方案是一种在促排中后期通过使用促性腺激素释放激素<span style="font-size: 16px; font-family: 微软雅黑, Microsoft YaHei; font-weight: 600;">拮抗剂</span>(GnRH-Antagonist)来防止提前排卵的方案。与传统的激动剂方案相比,它的作用机制是“即时的、可逆的阻断”,通过竞争性占据垂体GnRH受体,从而快速抑制内源性LH峰的提前出现,避免卵泡在未成熟时提前排掉。</span></p><p style="font-size: 16.002px;
