Summary

Luteal phase support is crucial in assisted reproductive techniques due to altered LH pulsatility. Vaginal progesterone offers effective luteal support with fewer side effects compared to other methods.

Area of Science:

  • Reproductive Endocrinology
  • Infertility Treatments

Background:

  • Assisted reproductive techniques (ART) are standard for infertility.
  • Gonadotrophin-releasing hormone analogues in ART necessitate luteal phase support.
  • These analogues disrupt normal luteal LH pulsatility.

Purpose of the Study:

  • To evaluate luteal phase support options in ART.
  • To compare the efficacy and safety of different luteal support methods.

Main Methods:

  • Review of existing literature on luteal phase support in ART.
  • Comparison of human chorionic gonadotrophin (HCG) and progesterone supplementation.
  • Focus on the route of progesterone administration (vaginal vs. intramuscular).

Main Results:

  • HCG is effective but carries a high risk of ovarian hyperstimulation syndrome.
  • Progesterone is the established standard for luteal support.
  • Vaginal progesterone provides direct endometrial delivery, achieving high local levels.
  • Vaginal progesterone demonstrates a very low incidence of side effects.

Conclusions:

  • Vaginal progesterone is a safe and effective alternative for luteal phase support in ART.
  • It bypasses systemic side effects associated with other methods.
  • Optimal endometrial exposure and reduced adverse events make it a preferred option.
