This study enhanced embryo transfer success by applying gentle cervical pressure with a vaginal speculum, significantly increasing clinical pregnancy and implantation rates in infertile patients undergoing intracytoplasmic sperm injection (ICSI).

Area of Science:

  • Reproductive Medicine
  • Infertility Treatment
  • Assisted Reproductive Technologies

Background:

  • Embryo transfer is a critical step in assisted reproductive technologies.
  • Embryo expulsion during transfer can lead to treatment failure.
  • A modified technique aims to prevent embryo loss by applying cervical pressure.

Purpose of the Study:

  • To evaluate a modified embryo transfer technique.
  • To assess the impact of gentle mechanical cervical pressure on pregnancy and implantation rates.
  • To reduce embryo expulsion during ICSI procedures.

Main Methods:

  • Prospective randomized controlled trial involving 639 infertile patients undergoing ICSI.
  • Study group: gentle pressure applied to the cervix via vaginal speculum during and for 7 minutes after embryo transfer.

  • Control group: standard embryo transfer without cervical pressure.

    • Main Results:

    • Significantly higher clinical pregnancy rate in the study group (67%) vs. control group (47.8%).
    • Significantly higher implantation rate in the study group (33.3%) vs. control group (21.5%).
    • Odds ratios: 1.39 for pregnancy, 1.54 for implantation.

    Conclusions:

    • Gentle mechanical pressure on the cervix during embryo transfer improves outcomes.
    • The modified technique enhances both clinical pregnancy and implantation rates.
    • This method offers a promising approach to optimize embryo transfer success.
