Preliminary experience with embryo intrafallopian transfer (EIFT)

Embryo intrafallopian transfer was accomplished in 10 patients. Approximately 48 hours after oocyte retrieval, the embryonic cleavage stage was evaluated and from two to six embryos were transferred to the fallopian tubes at the 2- to 8-cell stage using a laparoscopic technique. Five clinical pregnancies resulted; four patients have given birth to five healthy babies (one set of twins) and one had a miscarriage. These results are encouraging, and we believe that transfer of embryos to the fallopian tubes may be an alternative to GIFT or IVF treatment in selected groups of patients.
