Swedish father Ragnar Bengtsson, 26, has entered into an experiment that he hopes will help him breastfeed his future children.
The Stockholm family man has begun stimulating his breasts with a pump in a bid to produce milk.
"Anything that doesn't do any harm is worth trying out. And if it works it could prove very important for men's ability to get much closer to their children at an early stage," Bengtsson said.
Bengtsson is preparing to pump his breasts at three-hour intervals every day until the beginning of December. As a full time economics student at Stockholm University, he is not always going to be in a position to pump in private.
"I'm going to have to pull out the pump during lectures. But really it doesn't bother me if it makes people uncomfortable. If they have issues with it that's their problem," he said.
Male lactation is a relatively common side effect of hormone treatments, but Bengtsson has no plans to chemically induce the process. "If it works and the milk turns out to have a high nutritional value it could be a real breakthrough," he said.
