Abstract

The National Perinatal Statistics Unit of the University of Sydney, in association with the Fertility Society of Australia, set up a natonal register of in vitro (IVF) pregnancies in 1983 when there was concern that IVF might increase the risk of congenital malformations or chromosomal abnormalities. The results were presented to the IV and V World Congress1 and covered the first three reports2-4 for pregnancies resulting from fertilizations between 1979-1985 (1,215 pregnancies). Gamete intra-fallopian transfer (GIFT) pregnancies were too few to be discussed at that time. The fifth and most recent report5 published in December 1988 from 18 units in Australia and two units in New Zealand covered the 1987 fertilization cohort with deliveries up to September 1988. It included data on 920 IVF pregnancies in 1987 (a total of 3,247 in 1979-1987) and 548 GIFT pregnancies (a total of 816 in 1985-1987). In addition, the numbers and pregnancy rates for selected stages of IVF and GIFT for each unit were listed anonymously; the number of women treated by selected procedures such as embryo cryopreservation were also included. The IVF pregnancies after donor oocytes, sperm and embryos and frozen embryos were also reported.
