Assisted reproductive technology in Australia and New Zealand 2003 presents information on all assisted reproduction technology (ART) treatments that took place in 2003 and the resulting pregnancies and births. It is the second report using data from the Australian and New Zealand Assisted reproduction Database (ANZARD) implemented in 2002. The report includes information on ART treatment and presents specific data on pregnancy success rates and how they vary by treatment type, cause of infertility, and women's age. It also includes information on birth outcomes such as multiple birth, gestational age, birthweight and perinatal mortality.
