I’m sure you’ve been told about someone who had an IVF baby and then got pregnant again without the need for any more treatment. I’ve known a few people it has happened to, but hadn’t realised quite how common it can be – according to new research from Australia, a third of couples will go on to conceive naturally after successful fertility treatment.
A research team looked at the pregnancy rates between 18 months and two years after having a first child and found that 33% of women who’d had assisted conception went on to have a second pregnancy without medical help afterwards. Although some of the couples had been trying to get pregnant again, apparently a quarter of the second pregnancies were just totally unexpected – presumably because couples weren’t using contraception having assumed they couldn’t get pregnant. The second pregnancies without any further treatment were most often amongst those who had unexplained infertility.
The study is published in the Australian and New Zealand Journal of Obstetrics and Gynaecology and you can read more about it here.
