Being overweight may reduce a man's chances of fathering a baby, according to a study.
Scientists in the United States say they have found a link between a man's weight and the quality of his sperm.
They believe sperm starts to deteriorate as soon as men go beyond a healthy weight for their size.
They have suggested that men who become obese may no longer be able to father children because the quality of their sperm is so poor.
