Women who have had one baby using fertility treatment are likely to be able to have their next child in a similar way, Australian researchers report.

In the study, which the authors say is the first to quantify the success rates for a second live birth using assisted reproductive technology (ART), more than 35,000 women who had a child using the technology between 2009 and 2013 were followed up until the end of 2015.

Two out of five of these women attending fertility clinics in Australia and New Zealand returned to try for a second child using either IVF or intracytoplasmic sperm injection (ICSI), at a mean age of 36 years. All had used their own eggs for the first pregnancy.

Nearly three quarters of those returning to use ART for a second child used frozen embryos stored since their original fertility treatment.
