Assisted Reproduction Technology
Assisted Reproduction Technology (ART) is also sometimes also used to identify In vitro fertilization (IVF) but now includes many new techniques.
- Australia - 2008 292,156 women gave birth to 296,925 babies
- 3.2% women received ART treatment
- ranging from 1.4% in the Australian Capital Territory to 3.7% in Tasmania
- 34.1 years was the average age of women who received ART
- 62.7% of mothers who received ART treatment were having their first baby and 37.3% had given birth previously
- 51,017 treatment cycles reported to ANZARD in Australia and New Zealand in 2005.
- 91.1% were from Australian and 8.9% from New Zealand fertility centres
- an increase of 13.7% of ART treatment cycles from 2004.
- 35.5 years average age of women (35.2 years in 2002).
- Women aged older than 40 years has increased from 14.3% in 2002 to 15.3% in 2005.
Single Embryo Transfers (SET)
- Significant increase in the number of SET embryos transfer cycles (2002 28.4%, 2005 48.3%)
- increase of SET cycles resulted more singleton deliveries (singleton deliveries 2005 was 85.9%)
- single-embryo transfer babies had better outcomes compared to babies born to women who had a double-embryo transfer (DET).
- 2005 3,681 SET babies and 5,589 DET babies.
- Singletons babies - 96.1% SET, 61.6% DET
- Preterm babies - 11.7% SET, 30.6% DET
- Low birthweight liveborn babies - 8.0% SET, 25.0% DET
ART Perinatal Mortality Rate
- perinatal mortality rate was 14.7 deaths per 1,000 births (2005)
- 23.8% decrease from 19.3 deaths per 1,000 births in 2004
- Perinatal mortality rate was the lowest among singletons born following SET (7.3 deaths per 1,000 births) in 2005.
