New research by researchers in China shows that playing video games for about 1 hour a day will put men at risk of erectile dysfunction as well as a 3 times higher risk of decreased sperm count.
Researchers measured sex hormone levels as well as feelings of depression and anxiety in more than 200,000 men while they performed "leisure" activities such as watching television, driving and playing computer games.
The results showed that for every 1.2 hours (72 minutes) of playing games or doing other recreational activities on the computer each day, the risk of erectile dysfunction in men increased 3.5 times.

And “there is no evidence that watching TV or driving around” increases the risk of erectile dysfunction, suggesting that the problem is not simply a matter of sitting too much.
The study found that computer use was associated with lower levels of follicle-stimulating hormone (FSH - the hormone that stimulates sperm production) in participants' blood.
The new study did not specify what leisure activities the study participants did on their computers, but previous studies have shown that men who regularly watch pornography are at higher risk of erectile dysfunction and disinterest in regular sexual activity.
The researchers note that their study has several limitations, including that it only assessed men aged 40–69, and that it did not specify the severity of the disorder.
According to studies, the number of men seeking treatment for erectile dysfunction has skyrocketed in recent years. Some have even described it as a “silent epidemic.”
