Fertility & Information
Fertility treatment has become extremely common in Australia and New Zealand over the last few years. The Assisted Reproduction Technology in Australia and New Zealand 2006 report has recently been published and the rates of IVF treatment and success are increasing. The numbers of patients undergoing IVF has increased significantly for a number of reasons. These include religious tolerance, positive publicity surrounding IVF, the decreased cost to patients, particularly in Australia (because of the Safety Net), and less invasive forms of treatment.
There were 53,543 treatment cycles reported in Australia and New Zealand in 2006. This was a 13.7% increase on 2005 with 22.6% resulting in a clinical pregnancy (an ultrasound showing a foetal heart or sac) and 17.3% resulting in a live delivery. In 2006 there were 10,522 babies born in Australia and New Zealand as a result of fertility treatment. This was a 5% increase on 2005.
The average age of women undergoing fertility treatment in 2006 was 36.5 years and the proportion of women aged greater than 40 years of age increased to 16.1% in 2006. The number of embryos being transferred into the uterus has decreased over the years to the point where 27.1% of all treatment cycles resulted in only one embryo being transferred. As a result, the number of high order multiple pregnancies (twins and triplets) is decreasing and the proportions of singleton deliveries was 88% of all pregnancies as a result of treatment in 2006.
