Clinicians should individualize ovarian stimulation protocols for IVF, considering various gonadotropin regimens, GnRH antagonists, and minimal stimulation options for optimal patient outcomes and cost-effectiveness.

Area of Science:

  • Reproductive Endocrinology
  • In Vitro Fertilization (IVF)
  • Hormonal Therapies

Background:

  • Ovarian stimulation is a critical component of IVF treatment.
  • Various gonadotropin preparations and protocols exist, each with potential benefits and drawbacks.

Purpose of the Study:

  • To provide an updated overview of gonadotropin regimens for ovarian stimulation in IVF.
  • To analyze the efficacy and safety of different protocols, including urinary and recombinant gonadotropins, LH supplementation, GnRH agonists/antagonists, and minimal stimulation.

Main Methods:

  • A comprehensive literature review and critical analysis of key studies published within the last five years.
  • Focus on ovarian stimulation protocols for IVF.

Main Results:

  • Urinary and recombinant gonadotropins demonstrate comparable safety and efficacy, with cost influencing global adoption.
  • The role of luteinizing hormone (LH) supplementation remains debated, though beneficial in cases of severe LH suppression.
  • Gonadotropin-releasing hormone (GnRH) antagonists offer advantages over agonists, including fewer injections, shorter duration, and reduced risk of ovarian hyperstimulation syndrome (OHSS).
  • Minimal stimulation protocols present a cost-effective alternative with acceptable success rates.

Conclusions:

  • Individualized ovarian stimulation protocols are essential, tailored to patient physiology and history.
  • GnRH antagonists, particularly with an early and fixed start, appear more effective than agonists.
  • Further research is needed to clarify pregnancy rate discrepancies between GnRH antagonists and agonists.
