Abstract
This is the third annual report of the U.S. Registry of in vitro fertilization-embryo transfer (IVF-ET) and related practices. The present report describes the 1988 experiences of 135 U.S. member clinics with respect to treatments and outcomes. During 1988 the clinics reported performing 22,649 ovarian stimulation cycles, with 3,508 (15%) resulting in a clinical pregnancy and 2,627 (12%) in a live delivery. Ninety-three percent of the clinics had at least one delivery, and overall a total of 3,427 babies were born. The overall live delivery rates were 12% for IVF (based on 13,647 retrievals), 21% for gamete intrafallopian transfer (GIFT) (based on 3,080 retrievals), and 20% for IVF and GIFT in combination (based on 671 retrievals). In addition to these treatments, detailed results are presented for zygote intrafallopian transfer, frozen embryo transfers, and IVF of donated oocytes.
