Using Your Phone At Night May Cause Sperm Decline

By Johnathan P Cumberwell

We have long suspected that the radiation from wifi, mobile phones and other devices may have a negative effect on sperm quality. As well as on testosterone levels.

However, we have now gotten a tiny piece of the puzzle.

A research report has demonstrated that there is a link between use of phones, tables and other devices at night and after bedtime, and sperm quality.

This study, which was published in the journal Sleep, investigated semen samples from 116 men between the ages of 21 and 59 years, who were undergoing fertility evaluation.

The researchers found that those that were more exposed to light-emitting media devices in the evening and after bedtime, had a larger decline in sperm quality:

Mobile phone at night can cause decline in sperm quality
  • Sperm concentrations were lower
  • The ability of the sperm to swim properly was lower
  • The % of sperm that was unable to swim was higher

It is perhaps also fair to assume that these people had lower testosterone levels, however the study did not analyse this.

So what exactly is causing the decline in sperm quality?

Is it the bright lights from the devices? Is it the radiation? Or is the reason that people that spend more time with their devices actually sleep less?

The study did not offer an answer. And we probably don’t have an answer yet.

But I suspect that it is a combination of more than one factor. However, I do think that lack of sleep is a big reason.

A normal grown up person normally needs around 7-8 hours of sleep at night. Sleep is key for a number of restorative functions in your body, and above all for testosterone production.

If your devices are keeping you up at night so that you only get 5-6 hours of sleep, this is likely to significantly contribute to falling sperm quality.

The lesson?

Try to get enough sleep, and leave your devices alone for the last couple of hours before bedtime (if at all possible).
