A mother in her 50s who conceived after IVF treatment has given birth to triplets in Adelaide, it was widely reported today. In response to requests for information about other births to older parents, the AIHW National Perinatal Statistics Unit at the University of New South Wales has analysed available data from the national register on assisted conception and from birth registrations to determine what proportion of all births to older parents occur after assisted conception (IVF and GIFT) and to provide some information on pregnancy outcome.
Commenting on these findings, the Unit's Director, Associate Professor Paul Lancaster, said 'while IVF and other types of assisted conception have increased the number of births at older parental ages, the majority of births to these older parents (more than 90%) are still conceived naturally.
'With increasing age, donor eggs or sperm are more likely to be used to achieve conception. Among women who become pregnant after assisted conception in their 40s or 50s, about 50-60% go on and have a liveborn infant. We still lack information on how many births to parents of all ages occur after fertility drugs or artificial insemination.'
The key findings are as follows:
