Summary
Gonadotropin-releasing hormone (GnRH) analogs improve IVF outcomes by preventing premature LH surges. This review examines their effects on reproductive functions beyond preventing cycle cancellation, offering insights into diverse clinical protocols.
Area of Science:
- Reproductive Endocrinology
- In Vitro Fertilization (IVF)
Context:
- GnRH analogs have significantly improved IVF cycle success rates over the past decade.
- Their primary benefit is preventing premature luteinizing hormone (LH) surges and cycle cancellations.
Purpose:
- To review the diverse effects of GnRH analog administration in ovarian stimulation protocols.
- To analyze consequences on residual gonadotroph secretion, ovarian response, oocyte and conceptus quality, and endometrial receptivity.
- To differentiate specific effects based on various short-term and long-term clinical protocols.
Summary:
- GnRH analogs suppress pituitary secretion, preventing premature LH surges and luteinization, thereby enhancing IVF outcomes.
- This review investigates less-understood impacts of GnRH analogs on residual gonadotroph function, ovarian sensitivity, gamete and embryo quality, and uterine receptivity.
- The analysis aims to clarify these effects considering the wide variety of protocols used.
Impact:
- Provides a comprehensive overview of GnRH analog actions in IVF, extending beyond their established role in preventing cycle cancellation.
- Aids clinicians in understanding the nuanced effects of different GnRH analog protocols on multiple facets of reproductive function.
- Contributes to optimizing IVF strategies by elucidating the specific impacts on ovarian response and reproductive outcomes.
