Summary

GnRH antagonist protocols offer similar success rates to GnRH agonist protocols for infertility treatment in normal responders. These protocols reduce treatment days and do not require intervention for early E(2) changes.

Area of Science:

  • Reproductive Endocrinology
  • Infertility Treatment
  • Assisted Reproductive Technology

Background:

  • GnRH agonists have been standard for preventing premature luteinization in IVF.
  • GnRH antagonists offer a shorter, more flexible alternative.
  • Understanding GnRH antagonist efficacy in normal responders is crucial.

Purpose of the Study:

  • To review the application and outcomes of GnRH antagonists in normal-responding patients undergoing infertility treatment.
  • To compare GnRH antagonist protocols with GnRH agonist protocols.
  • To assess the significance of early estradiol (E2) changes during GnRH antagonist use.

Main Methods:

  • Review article synthesizing existing literature.
  • Analysis of case studies involving GnRH antagonist protocols.
  • Evaluation of IVF outcomes in relation to E2 levels.

Main Results:

  • GnRH antagonist protocols yield equivalent IVF outcomes to GnRH agonist protocols in normal responders.
  • GnRH antagonist use significantly reduces the number of treatment/injection days.
  • A decrease or plateau in E2 levels post-GnRH antagonist initiation has no negative impact on IVF success.

Conclusions:

  • GnRH antagonists are a viable and flexible option for normal-responding patients in infertility treatment.
  • Intervention (e.g., LH add-back) is unnecessary to counteract early E2 fluctuations during GnRH antagonist stimulation.
  • Clinicians should consider ovarian physiology and GnRH antagonist mechanisms for optimal patient management.
