Numerous studies link smartphone or tablet use at night to trouble falling asleep. Now, a new study finds yet another compelling reason to avoid such gadgets before bed — at least for men who hope to one day start a family (hy vọng một ngày nào đó sẽ lập gia đình). New research by the American Academy of Sleep Medicine notes a correlation (mối tương quan) between nighttime digital media use and poor sperm quality (chất lượng tinh trùng).

These preliminary results (kết quả ban đầu/sơ bộ) suggest that the more often a man uses digital devices, both in the evening in general and after bedtime, the more his sperm quality will decline. Among studied males who reported regular and copious electronic device use at night, three measures of sperm quality (concentration, motility and progressive motility) were lower.

For reference, progressive motility refers to the ability of a man’s sperm to “swim” correctly. This, of course, is an essential part of the conception process.
