OBJECTIVE: To summarize the procedures and outcomes of assisted reproductive technology (ART) initiated in the United States in 1992. DESIGN: Data were collected on an annual summary form and submitted to The American Fertility Society/Society for Assisted Reproductive Technology Registry. PARTICIPANTS: Two hundred forty-nine programs submitted data on procedures performed in 1992. Data were collected in October 1993 so that outcome of all pregnancies established would be known. MAIN OUTCOME MEASURES: The outcomes measured included clinical pregnancy, ectopic pregnancy, abortion, stillbirth, delivery, and congenital abnormality. RESULTS: Programs reported initiations of 37,955 cycles of ART treatment, excluding frozen embryo and donor oocyte cycles. Of these, 29,404 cycles initiated were IVF with 16.8% deliveries per retrieval, 5,767 were cycles of GIFT with 26.3% deliveries per retrieval, 1,993 cycles of zygote intrafallopian transfer with 22.8% deliveries per retrieval, and 791 were combination cycles, combining IVF and one of the tubal transfer techniques, resulting in 27.9% deliveries per retrieval. In addition to these cycles initiated in 1992, 5,814 frozen ET procedures were reported, either as separate procedures or in combination with another ART procedure, with 13.9% deliveries per procedure, and 2,032 donor oocyte or surrogacy cycles were initiated with an overall success of 31.3% deliveries per retrieval. As a result of all procedures, a total of 7,355 deliveries were reported. CONCLUSIONS: In 1992, there were more programs offering more treatment cycles of ART. Average success rates exhibited only a small increase compared with previously reported summaries.
