Men might want to think twice before reaching for their smartphone at night. A new study found correlations between electronic media use at night and poor sperm quality.
Preliminary results show that greater self-reported exposure to light-emitting media devices in the evening and after bedtime is associated with a decline in sperm quality. Sperm concentration, motility and progressive motility — the ability of sperm to “swim” properly — were all lower, and the percentage of immotile sperm that are unable to swim was higher, in men who reported more smartphone and tablet usage at night.
