It seems that a child’s sex may all be down to its father’s waistline.

A new study has found that overweight and obese men are significantly more likely to father sons than their slimline counterparts.

The research, which was published in the journal of fertility and sterility, studied 8,500 couples undergoing fertility treatment.

While the slim men fathered 611 boys and 569 girls – which is perfectly in line with the typical seven per cent pro-male sex ratio – the overweight and obese men were a massive 27 per cent more likely to father sons.

Commenting on the groundbreaking research, Peking University Hospital who conducted the study said: ‘The present study is the first to report that overweight and obese men lead to a higher sex ratio at birth compared with normal weight men.’



Although the subject obviously needs a lot more research to work at how and why this could be the case, we’re sure that won’t stop men filling up on pies in the hope of having that much longed for son.
