This is true,
A more likely explanation is that people typically use cellphones > while sedentary.

Not to mention of course that correlation does not imply causation. Possibly men with higher sperm counts have better things to do than spend their time talking on the phone.
It would be interesting to see if that study was corrected for age, as well.
