In-vitro fertilisation (IVF) and related techniques delivered 2,715 babies (1.0% of all Australian births) conceived in 1994 and born up to September 1995, according to a report released today by the Australian Institute of Health and Welfare, and the Fertility Society of Australia.
The report, Assisted Conception, Australia and New Zealand, 1994 and 1995, presents data collected from 24 Australian and five New Zealand IVF units by the Institute's National Perinatal Statistics Unit. The data detail IVF and gamete intrafallopian transfer (GIFT) treatments.
'More than 20,000 babies conceived by IVF and GIFT have been born in Australia since 1980', said AIHW National Perinatal Statistics Unit Director, Dr Paul Lancaster.
The use of microinsemination in treating infertility has increased sharply in recent years. In 1995, 30% of all assisted conception involved microinsemination by microinjection of sperm into eggs, or the transfer of frozen/thawed embryos after fertilisation by microinjection.
'Pregnancy rates and results for the main type of microinsemination, intracytoplasmic sperm injection (ICSI), were similar to those for conventional IVF', said Dr Lancaster.
'Based on almost 800 pregnancies and more than 700 births after microinsemination, pregnancy outcome is similar to that for other IVF pregnancies.'
