Talking on your mobile for more than an hour - or using it while it charges - increased the chances of having an abnormal concentration of sperm to 61 per cent.
Male infertility constitutes between 30 and 40 per cent of all infertility cases.
Dr Zilberlicht told Israeli television station Channel 2: “In light of the results of the study, it is certainly recommended [that men] shorten the duration of calls and avoid carrying the device near their groins, sleeping next to it, speaking on it when it’s charging and use headphones or a headset as much as possible.”
The doctor also said that “men should turn their phones off while charging them.”
Researchers looking into the “association between characteristics of cell phone usage and semen quality” gave surveys to a sample of 106 men, who answered questions about their mobile phone usage.
