In video games, there always some form of competition present.  Gamers give it there all to best each other in the field of virtual combat, and testosterone may only increase that need to prove themselves -- and their manhoods.

Well, Dutch researchers at the Utrecht University have some discouraging news for boastful male gamers.  In a study conducted by Dr. Marcel Waldinger, nearly 200 Dutch men who were a bit too quick in the sheets were shown to have a unique gene controlling their serotonin.

In the men who appeared to have this issue, the hormone was less active between the nerves in the section of the brain that controls ejaculation.

"This contradicts the idea, which has been common for years, that the primary form of premature ejaculation is a psychological disorder," Dr. Waldinger commented.

For a month, the subjects' female partners were asked to use a stopwatch during moments of intimacy in order.  Talk about working under pressure!

Paula Hall, a sexual psychotherapist for relationship therapy service Relate, suggested that men with this alleged problem-gene are generally fast reactors. 

"These men have very quick reflexes," she explained.  "They may be excellent at playing tennis or computer games, for example."

There's no cause and effect here -- gaming won't cause premature ejaculation or vice versa -- but a correlation appears to exist in the newly discovered gene that handles serotonin interaction.  A third of men are thought to suffer from premature ejaculation, though there is currently no medication for this condition.

So next time an adversary won't quit bragging about his victory, go ahead and point out his flawed gene.
