In the present study we investigated the cause of GnRHa's failure to trigger oocyte maturation and present an effective rescue protocol for use when failure occurs.
Case reports.
One in vitro fertilization (IVF) center.
PATIENT(S): Eight cases of failure of GnRH agonist (GnRHa)-triggered oocyte maturation and one case of GnRHa successfully triggered oocyte maturation, despite a weak response in the LH-RH test.
MAIN OUTCOME MEASURE(S): All cases were successfully rescued by re-triggering maturation using HCG, with seven of the eight patients achieving ongoing pregnancy and successful delivery.
RESULT(S): In three patients the cause of the oocyte maturation failure was likely temporal or continuous severe down-regulation of the hypothalamus-pituitary-axis, the cause was unknown in the other five patients.
CONCLUSION(S): In cases where GnRHa fails to trigger oocyte maturation, a rescue protocol entailing re-triggering with HCG can produce successful outcomes.
本研究旨在探讨 GnRH 激动剂(GnRHa)诱发卵母细胞成熟失败的原因,并提出一种有效的补救方案。
病例报告。
一个体外受精(IVF)中心。
8 例 GnRHa 触发卵母细胞成熟失败,1 例 GnRHa 触发卵母细胞成熟成功,尽管 LH-RH 试验反应较弱。
所有病例均通过 HCG 再次触发成熟而成功获救,其中 7 例患者获得持续妊娠并成功分娩。
3 例患者卵母细胞成熟失败的原因可能是下丘脑-垂体轴的时间性或持续严重下调,另外 5 例患者原因不明。
在 GnRHa 未能触发卵母细胞成熟的情况下,采用 HCG 再次触发的补救方案可以获得成功的结果。
