Trouser pockets are not the place to keep cell phones, if one wishes sperm to remain vital, Science Direct reports.
A recent study by the University of Exeter states that cell phones may have an adverse effect on the quality of sperm.
British researchers studied sperm samples from 1,492 men, which were gathered at fertility clinics and research centres.
The quality of the semen was evaluated by measuring the number, mobility and frequency of the sperm.
Men who kept their cell phones in their trouser pockets experienced a decrease of 8 per cent in the mobility of their sperm. The semen's vitality dropped by 9 per cent.
According to researchers the deterioration of sperm correlates with how long a man keeps the phone in the pocket of his trousers, and how much electromagnetic radiation the phone transmits.
The study also indicated that up to 14 per cent of couples in countries with a high standard of living experience difficulties in conceiving. In many countries it has also been noted that the quality of men's sperm has plunged in an unexplainable way.
"When taking into account how common the use of cell phones in these countries is, it is necessary to study its possible effects on sperm quality", researchers state.
