Sydney: National Perinatal Epidemiology and Statistics Unit, the University of New South Wales.<ref> August 2013 In 2011, there were 66,347 treatment cycles undertaken in Australia and New Zealand. Of these, 23.1% resulted in a clinical pregnancy and 17.5% in a live delivery (the birth of at least one liveborn baby).There were 12,623 babies (including 12,443 liveborn) born following ART treatment in 2011.

A continuing trend in ART treatment in Australia and New Zealand has been the reduction in the rate of multiple deliveries, with a decrease from 10.0% in 2007 to 6.9% in 2011. This was achieved by clinicians and patients shifting to single embryo transfer, with the proportion increasing from 63.7% in 2007 to 73.2% in 2011. Importantly, this decrease in the multiple delivery rate was achieved while clinical pregnancy rates remained stable at about 23.0% per initiated cycle.

For the first time, the 2011 annual report presents cumulative pregnancy and live delivery rates. For women who undertook their first autologous fresh cycle between 2009 and 2011, the cumulative live delivery rate was 21.1% after the first cycle, increasing to 31.1% after two cycles, 36.0% after three cycles, 38.6% after four cycles, and 40.0% after five cycles. The cumulative live delivery rate did not increase markedly with additional treatments after five cycles.
