When the Dual Trigger Fails: Understanding Missed Oocyte Retrieval After Combined hCG and GnRHa 🤔 Dual triggering with hCG and GnRHa is designed to maximize oocyte maturation by mimicking both the LH and FSH surge.

Such failures are often linked to suboptimal timing, inadequate LH release, or patient-specific factors like diminished ovarian reserve. Recognizing these risks early and chec
