Washington, May 28 (ANI): A Finnish study suggests that premature ejaculation may be a genetic disorder.

Researchers from Turku came to this conclusion after interviewing more than three thousand men-all pairs of male twins and their older or younger brothers-about the first time they had sex.

Most of the persons surveyed revealed that they had suffered from erectile dysfunction and premature ejaculation at their first sexual encounter.

The research confirms the belief that these common problems are often related to external factors like intoxication or nervousness due to peer pressure.

However, according to the researchers, premature ejaculation also appears to be strongly linked to genetic factors, and is not just psychological.

A previous study conducted by researchers in The Netherlands also linked premature ejaculation to a gene for serotonin regulation in a group of two hundred men.

The current study independently shows a genetic link to premature ejaculation in a much larger group, and rule out environmental factors.

Lead researcher David Goldmeier says 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.

He and reviewer Taylor Segraves, however, insist that medicines will not be the only solution. They say that psychotherapy will continue to be a valuable and useful form of treatment for sexual dysfunctions, even for those with a genetic cause.

The study has been published in the Journal of Sex and Marital Therapy. (ANI)
