Abstract
This is the first report of the United States Registry of in vitro fertilization/embryo transfer (IVF/ET) and related practices. Summary data from 1985 and 1986, collected from retrospective reporting, are presented. There were 2389 and 2864 IVF cycles with embryos transferred in 1985 and 1986, respectively. In 1985 and 1986, 337 (14.1%) and 485 (16.9%) of the transfer cycles, respectively, resulted in clinical pregnancies. The number of cycles with frozen embryos transferred increased from 26 to 112 between 1985 and 1986. In 1986, there were 7 clinical pregnancies through frozen ET. In 1985, there were 56 gamete intrafallopian transfer (GIFT) procedures, whereas in 1986 there were 466 such treatment cycles. The number of clinical pregnancies by GIFT increased from 3 to 108 between 1985 and 1986.
