Laparoscopic Zygote Intra-Fallopian Transfer (ZIFT) is a well-tolerated fertility procedure. This study found a 24% pregnancy rate with minimal discomfort when zygotes were transferred to a single fallopian tube.

Area of Science:

  • Reproductive Medicine
  • Minimally Invasive Surgery

Background:

  • Zygote Intra-Fallopian Transfer (ZIFT) is an assisted reproductive technology.
  • Evaluating the feasibility and patient tolerance of laparoscopic ZIFT under local anesthesia is important for improving patient outcomes.

Purpose of the Study:

  • To assess the safety, tolerability, and pregnancy outcomes of laparoscopic ZIFT performed under local anesthesia with intravenous analgesia.

Main Methods:

  • Twenty-nine laparoscopic ZIFT procedures were conducted in 21 patients.
  • Procedures utilized local anesthesia supplemented with intravenous analgesia.
  • Zygote transfer was optimized to a single fallopian tube to minimize patient discomfort.

Main Results:

  • The laparoscopic ZIFT technique was generally well-tolerated by patients.

  • Discomfort was primarily associated with fallopian tube manipulation, effectively managed by single-tube transfer.
  • Seven pregnancies were achieved, with three deliveries and one ongoing pregnancy, indicating a 24% success rate.

    • Conclusions:

    • Laparoscopic ZIFT under local anesthesia is a feasible and tolerable procedure.
    • Optimizing zygote transfer to one fallopian tube enhances patient comfort.
    • The technique demonstrates a promising pregnancy rate, offering a viable option for infertility treatment.
