A scientific study has found evidence that male laptop users could be damaging their fertility.

Researchers at New York's State University warned this week that a man balancing a portable computer on his lap risk increasing the temperature around their scrotum to a level where their sperm count could be damaged.

The study, which was published in scientific journal Human Reproduction on Thursday, warned that the combination of warm laptop and closely pressed thighs could raised the temperature of a man's scrotum by as much as 2.8 degrees Celsius.

"Until further studies provide more information on this type of thermal exposure, teenage boys and young men may consider limiting their use of laptop computers on their laps, as long-term use may have a detrimental effect on their reproductive health,'' said Yefim Sheynkin, an associate professor of urology and director of male infertility and microsurgery at New York's State University, in a statement.

Dell and Fujitsu-Siemens, two of the world's leading laptop makers, were both unable to comment on the study at the time of writing. UK-based Acer, though, was more forthcoming.

"I have been using laptop computers ever since their inception and have three very healthy children and hope to have many more," said Paul Cook, managing director of Acer UK.
