Laparoscopic zygote intrafallopian transfer using augmented local anesthesia.

In this study, 29 laparoscopic ZIFTs were performed in 21 patients using local anesthesia augmented with intravenous analgesia. The technique was well tolerated; significant discomfort arose only when the fallopian tubes were manipulated and was minimized by transferring zygotes to one tube only. Seven pregnancies resulted, of which three have delivered and one is ongoing.
