Rationale: In the majority of cases, egg retrieval is performed by a transvaginal approach under ultrasound guidance for in vitro fertilization. Gamete intrafallopian transfer (GIFT) involves the retrieval of oocytes by laparoscopy, immediate placement of the oocytes in a catheter with washed, motile sperm, and placement of the gametes into the fimbriated end of the fallopian tube. Zygote intrafallopian transfer (ZIFT) and tubal embryo transfer (TET). In these procedures eggs are retrieved and incubated with the mans sperm. The eggs are transferred back to the womans body at a much earlier stage of cell division than in IVF and, as in GIFT, are placed in the fallopian tube or tubes and not in the uterus. In TET, the placement is done at the embryo stage. These procedures allow fertilization to be documented, which is not possible with GIFT, and the pregnancy rate is theoretically increased when the fertilized ovum is placed in the fallopian tube.
