Summary

GnRH antagonist use in intrauterine insemination (IUI) cycles reduced weekend procedures from 25% to 8%. While increasing stimulation length and gonadotropin dose, it did not appear to decrease pregnancy rates, though more data is needed.

Area of Science:

  • Reproductive Endocrinology
  • Infertility Treatments

Background:

  • Intrauterine insemination (IUI) procedures frequently fall on weekends, causing inconvenience for patients and physicians.
  • Current protocols lack flexibility for scheduling around non-working days.

Purpose of the Study:

  • To evaluate the efficacy of gonadotropin-releasing hormone (GnRH) antagonist in minimizing weekend IUI procedures.
  • To assess the impact of GnRH antagonist on cycle parameters and pregnancy rates in IUI.

Main Methods:

  • A prospective study involving patients undergoing IUI.
  • Utilized GnRH antagonist to potentially shift IUI timing away from weekends.
  • Standardized monitoring occurred on Wednesdays (blood sampling and ultrasonography).

Main Results:

Related Experiment Videos

  • GnRH antagonist use significantly reduced weekend IUI from 25% to 8%.
  • 63% of patients required GnRH antagonist injections.
  • Stimulation length and cumulative gonadotropin dose increased with GnRH antagonist use.
  • Pregnancy rates in IUI cycles were not demonstrably decreased by GnRH antagonist administration.

Conclusions:

  • GnRH antagonist can effectively reduce the need for weekend IUI.
  • The use of GnRH antagonist may prolong stimulation and increase gonadotropin dosage.
  • Further research is required to definitively conclude on the effect of GnRH antagonists on IUI pregnancy rates.
