If you lack staying power in bed, blame it on genesMay 28th, 2009 - 12:43 pm ICT by IANS
London, May 28 (IANS) Premature ejaculation is genetic, says a new study.
Researchers from Turku, Finland, interviewed more than 3,000 men, all pairs of male twins and their older or younger brothers, about the first time they had sex.
Many participants reported that they had suffered from erectile dysfunction (ED) and premature ejaculation (PE) during their first sexual encounter.
These common problems are often attributed to external factors, such as drunkenness or nervousness due to peer pressure.
This research confirms that such factors do cause ED. But premature ejaculation appears to be strongly linked to genetic factors, and is not just psychological.
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.
Faculty of 1000 (F-1000) Medicine member David Goldmeier 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, said an F-1000 release.
