Summary

Programmed ovulation induction showed a high rate of spontaneous ovulation. While pregnancy rates were similar, using follicle-stimulating hormone (FSH) with serum estradiol monitoring improved results in assisted reproduction.

Area of Science:

  • Reproductive Endocrinology
  • Infertility Treatment
  • Assisted Reproductive Technology

Background:

  • Ovulation induction is a key component of assisted reproductive technology (ART).
  • Programmed ovulation induction aims to optimize oocyte retrieval timing.
  • Previous protocols involved progestagen pretreatment with ethynodiol diacetate.

Purpose of the Study:

  • To compare programmed ovulation induction with classical monitoring in ART.
  • To evaluate the impact of different stimulation protocols (clomiphene citrate/hMG vs. FSH/hMG) on outcomes.
  • To assess the incidence of spontaneous ovulation and pregnancy rates.

Main Methods:

  • Forty-two patients underwent programmed ovulation induction following ethynodiol diacetate pretreatment.

  • Two stimulation groups: Group A1 (clomiphene citrate + human menopausal gonadotropin [hMG]) and Group A2 (follicle-stimulating hormone [FSH] + hMG).
  • Comparison against randomized control groups with classical monitoring.

    • Main Results:

    • A significantly higher proportion of spontaneous ovulations occurred in the programmed group (8/42) versus the nonprogrammed group (0/42).
    • No significant differences in oocyte yield or embryo replacement per cycle between groups.
    • Pregnancy rates: 24% (4/17) in the programmed group vs. 32% (10/31) in the nonprogrammed group.

    Conclusions:

    • Programmed ovulation induction is associated with an increased risk of spontaneous ovulation.
    • The use of FSH for stimulation combined with serum estradiol verification (semi-programmed method) appears more promising.
    • Further research is needed to optimize programmed ovulation induction protocols for improved ART success rates.
