New studies suggest that premature ejaculation might be a genetic disorder.

Finnish researchers found that a lot of men suffered from suffered from erectile dysfunction and premature ejaculation at their first sexual encounter. More than 3 000 men were interviewed; all were pairs of male twins and their older or younger brothers.

Erectile dysfunction and premature ejaculation are common problems and are often attributed to external factors, such as intoxication or nervousness due to peer pressure. This research confirms that these factors do cause erectile dysfunction, but also found a strong genetic link.

Earlier study
In an earlier study, researchers in The Netherlands linked premature ejaculation to a gene for serotonin regulation in a group of 200 men.

The new data from Finland independently show a genetic link to premature ejaculation in a much larger group, and rule out environmental factors. David Goldmeier, from the Faculty of 1 000 Medicine notes that the increasing evidence for a genetic cause of premature ejaculation opens the way for the development of new drug treatments - something that many men might benefit from.

However, both Goldmeier and reviewer Taylor Segraves emphasise that drug therapy is not the only solution: psychotherapy will continue to be a valuable and useful form of treatment for sexual dysfunctions - even those with a genetic cause. – (EurekAlert!, May 2009)
