Women using IVF to get pregnant should be aware that they will be more likely to have a boy than a girl, say experts.
Australian researchers found the odds of a boy went up from 51 in 100 when conceived naturally to 56 in 100.
But another assisted reproduction technique called ICSI, which singles out the sperm that will fertilise the IVF egg, makes a girl more likely.
The study reported in the British Journal of Obstetrics and Gynaecology looked at nearly 14,000 births.
This group comprised all live births following fertility treatment in clinics in Australia and New Zealand between 2002 and 2006.
In the UK, over 35,000 women a year undergo IVF.
The University of New South Wales researchers say patients should be counselled about the side effects of different assisted reproduction techniques.
