OBJECTIVE: To summarize the experience of a single center with laparoscopic zygote intrafallopian transfer (ZIFT) performed exclusively among patients with high-order repeated implantation failure (RIF) following in vitro fertilization-embryo transfer (IVF-ET).
METHODS: A retrospective cohort study was performed at the Edith Wolfson Medical Center, a tertiary referral university hospital located in Holon, Israel. A group of 176 patients with 8.15±3.9 previously failed IVF-ET cycles underwent 280 ZIFT procedures between 1995 and 2010. The main outcome measure was the live birth rate per patient treated.
RESULTS: In all, there were 274 fresh and 6 frozen ZIFT cycles recorded in the study cohort, resulting in 96 clinical pregnancies per attempt (34.3%) and 72 live births (25.7%). The live birth rate per patient was 39.8%.
CONCLUSION: The use of ZIFT remains a powerful tool in the clinical management of selected patients with high-order RIF. This procedure should be kept in mind when all other measures fail among patients with at least 1 unobstructed fallopian tube.
