Recent changes in IVF clinical practice: data linkage to investigate their impact on fetal growth and birth defects.

在澳大利亚，每25个新生儿中就有1个是通过试管婴儿治疗受孕的，随着晚育的持续趋势，这一比例正在上升。这项研究将使用相关的人口数据来评估在过去十年中IVF实践发生重大变化后IVF受孕儿童的胎儿生长和出生缺陷。国际上关于使用较新的体外受精技术后的健康结果的数据有限，而且数据不足，无法进行适当的治疗前咨询。

In Australia 1 in 25 births are conceived from IVF treatment and this is increasing with the continuing trend towards later childbearing. This study will use linked population data to assess fetal growth and birth defects in IVF-conceived children following major changes to IVF practice in the last decade. There are limited data internationally on health outcomes following the use of more recent IVF techniques and insufficient data to allow for adequate pre-treatment counselling.
