Facebooked: Laptop 'cooked' man's sperms, say doctors
As a result, the 30-year-old electrician Scott Reed and his wife, Laura, were finding it hard to conceive.
Reed started using his laptop on a table instead and three months later his wife Laura became pregnant with a daughter, the 'Daily Mail' reported.
"I've never heard of this happening before, when the doctors told us it was a real shock," Laura said.
"Scott would use his laptop in the evenings for a couple of hours on and off while we were watching television. He would use it for work and general things like Facebook. We had absolutely no idea the damage it was causing him," she said.
The couple, from Clanfield in Hampshire, visited their doctor after trying for a baby for six months without success.
Initially it was thought Scott's fertility had been affected by mumps, which he had suffered at the age of 21.
"You don't think it will be that hard to get pregnant. We both went back to have a chat and the doctor put Scott forward for a fertility test," she said.
The couple were then referred to a hospital for tests, which revealed Scott was producing a healthy amount of sperm but they had suffered heat damage.
Under the microscope it was possible to see that the tail of the sperm had coiled around the head, meaning it couldn't swim quickly to the egg.
