Frequent mobile phone usage damages sperm count.
Mobile phone usage damages a man's sperm count
Previous research has shown that male sperm count has dropped by half globally over the past 50 years and a team at the University of Geneva has now discovered that sperm concentration in those using a phone over 20 times a day fell by 21 per cent in comparison to those who did not use a mobile more than once a week.
In more positive news, the impact on sperm count has eased over the past 13 years as phone technology has advanced.
Alison Campbell, chief scientific officer of Care Fertility - a network of fertility clinics - said: "This is a fascinating and novel study which should not cause alarm or drastic changes in habits.
"Men looking to conceive, or wanting to improve their sperm health should exercise (but not overheat in their groin area), eat a balanced diet, maintain a healthy weight, avoid smoking and limit alcohol and seek help if they are having problems conceiving."
