Summary
Transvaginal ultrasound-guided gamete intrafallopian transfer (GIFT) showed a lower pregnancy rate (20%) compared to laparoscopic GIFT (35%). However, it remains a viable alternative for certain fertility treatments.
Area of Science:
- Reproductive Medicine
- Assisted Reproductive Technologies
Background:
- Gamete intrafallopian transfer (GIFT) is an assisted reproductive technology.
- Conventional GIFT procedures typically utilize laparoscopy.
Purpose of the Study:
- To compare pregnancy rates (PRs) between transvaginal ultrasound-guided GIFT and conventional laparoscopy-based GIFT.
Main Methods:
- Retrospective case-controlled study.
- Twenty transvaginal GIFT cycles were matched with 60 laparoscopic GIFT cycles.
- Matching criteria included patient age, prior GIFT attempts, and egg numbers.
Main Results:
- The PR for transvaginal GIFT was 20.0% (95% CL 13%–27%).
- The PR for laparoscopic GIFT was 35.0% (95% CL 23%–50%).
Conclusions:
- Transvaginal GIFT appears less effective than laparoscopic GIFT with current techniques.
- Transvaginal GIFT offers a practical alternative to ovarian stimulation/intrauterine insemination and peritoneal ovum-sperm transfer.
