This study compared in vitro fertilization with embryo transfer to the uterus (IVF+ET) versus pronuclear stage tubal transfer (IVF+PROST) in infertile couples. IVF+PROST resulted in a triplet pregnancy, while IVF+ET led to a missed abortion.

Area of Science:

  • Reproductive Medicine
  • Infertility Treatment
  • Assisted Reproductive Technology

Context:

  • Infertility affects a significant number of couples worldwide.
  • Assisted reproductive technologies (ART) offer solutions for infertility.
  • Comparing different ART protocols is crucial for optimizing outcomes.

Purpose:

  • To evaluate the efficacy of in vitro fertilization with embryo transfer to the uterus (IVF+ET) versus in vitro fertilization and pronuclear stage tubal transfer (IVF+PROST).
  • To assess pregnancy rates and outcomes in infertile patients undergoing two distinct ART protocols.

Summary:

  • Ten infertile couples underwent controlled ovarian hyperstimulation using FSH, HMG, and Gn-RH agonist. Oocyte retrieval, fertilization, and embryo transfer were performed.
  • Nine patients responded to stimulation, yielding 69 oocytes, with 81.15% mature and 74.55% fertilization rate.

  • One patient in the IVF+PROST group achieved a triplet pregnancy, and one in the IVF+ET group experienced a missed abortion.

    • Impact:

    • The study suggests potential differences in pregnancy outcomes between IVF+ET and IVF+PROST.
    • Further research is needed to confirm the comparative effectiveness of these ART methods.
    • Findings contribute to the understanding of ART protocols for managing infertility.
