The BBC says:
Obese men have poorer quality sperm, perhaps because too much fat around their testicles causes them to heat up, scientists have suggested.
University of Aberdeen researchers looked at the sperm of over 2,000 men in couples having problems conceiving.
The heaviest men had a higher proportion of abnormal sperm, as well as other problems.
...
Dr Ian Campbell, chair of the charity Weight Concern, said it was known that overweight people had a tendency to have fewer children.He said there had been a suspicion that was mainly due to lack of opportunity.
"But if weight actually has a detrimental effect on sperm quality, that's really interesting," he said.
"It's one more reason for men to lose weight."
More demonisation of fat people. It's amazing this kind of trite research gets funded. Surprise, fat people are not as healthy as non-fat people, who would have thought it. And that's one reason why there is "lack of opportunity" (which Campbell breezily dismisses, not seeming to realise this is related to health).
