Premature ejaculation may be genetic

Wednesday 8th October, 2008

A new Dutch study has suggested that men who ejaculate prematurely may be caused to do so by their genes.

The study involved up to 200 men of which some suffered with ejaculation too soon whilst having sexual intercourse. Each man who ejaculated prematurely had a particular version of a gene that controls the hormone ‘serotonin’.

The men with the gene were found to ejaculate twice as fast as other men involved in the study. According to the researchers at the Utrecht University in the Netherlands, serotonin levels control how rapid ejaculation takes place.

Over the course of a month, 89 volunteers who suffer with ‘primary premature ejaculation’ were asked to use a stopwatch at home to measure how quickly they ejaculated each time they had sex with their female partners. These results were then compared against 92 men who had no history of the problem.

Those who suffered premature ejaculation had less active serotonin between brain nerves that control ejaculation. The lower activity of the serotonin hormone suggests nerve signals are not transferring in the usual way.

“This contradicts the idea, which has been common for years, that the primary form of premature ejaculation is a psychological disorder,” said Dr Marcel Waldinger, lead researcher of the study.

Paula Hall, a sexual psychotherapist for Relate, echoed Dr Waldinger’s comments but believes the condition can be in the mind too.

“Premature ejaculation is definitely not purely psychological,” she said.

“But there can be a psychological element. The acid test is how much control they have on their own. If the problem only occurs with their partner then it is more likely to be psychological.”

Primary premature ejaculation tends to occur in men who have generally fast reactions and is believed to affect a third of all men.

“These men have very quick reflexes,” explained Ms. Hall.

“They may be excellent at playing tennis or computer games, for example.”

There is no medication on the market to treat premature ejaculation. This study may lead to a drug becoming available but in the meantime treatments involve alternative medicine and complementary therapy methods such as Counselling, NLP and Cognitive Behaviour Therapy. The use of anti-depressants has been prescribed not to treat depression but for the side effect of delaying ejaculation.
