In vitro fertilization/embryo transfer in the United States: 1987 results from the National IVF-ET Registry.

This is the second annual report of the U.S. Registry of IVF-ET and related practices. The present report describes the 1987 experiences of 96 U.S. member clinics with respect to treatments and outcomes. During 1987, 14,647 in vitro fertilization (IVF) and/or gamete intrafallopian transfer (GIFT) stimulation cycles were performed; there were 490 frozen embryo and 60 donor oocyte transfers. Ninety percent of the clinics had at least one delivery, and overall, a total of 1858 babies were born. The overall clinical pregnancy rates were 16% for IVF (based on 8725 retrievals), 25% for GIFT (based on 1968 retrievals), and 28% for IVF and GIFT in combination (based on 199 retrievals). The results for each procedure are described in detail.
