Opting for in-vitro fertilization to conceive increases the chances of the baby being a boy, a new survey published in the British Journal of Obstetrics and Gynaecology reveals.
Researchers from the University of New South Wales in Australia studied more than 14,000 live births in fertility clinics in Australia and New Zealand over a period of four years between 2002 and 2006 and found that while the natural chance of the baby being a boy was 51 percent, it shot up to 56 percent when conceived using IVF treatment.

The editor-in-chief of the BJOG Professor Philip Steer said that prospective parents should be made aware of the possibility of a particular treatment influencing the sex of the baby, adding that an imbalance in the secondary sex ratio (SSR) should not be created unintentionally.
"t is important that we don't allow such imbalances to occur unintentionally, simply because we have neglected to study the factors that influence the secondary sex ratio in the increasing proportion of the population who use assisted reproductive technology", he said.
