More than three thousand men – all pairs of male twins and their older or younger brothers- were interviewed about their first sexual experience by researchers in Turku, Finland in an attempt to draw a connection between premature ejaculation and genes. Many participants in the study reported that they had suffered from erectile dysfunction and premature ejaculation at their first sexual encounter. Many problems attributed to the problem were found to be common across participants from different demographics. These common problems are often attributed to external factors, such as intoxication or nervousness due to peer pressure. This research confirms that such factors do cause erectile dysfunction. On the other hand, it is also very apparent that premature ejaculation appears to be strongly linked to genetic factors, and is not just psychological. In an earlier study conducted on premature ejaculation, researchers in The Netherlands linked the problem to a gene for serotonin regulation in a

group of two hundred men. This independent research from Finland shows a genetic link to premature ejaculation in a much larger group, and rules out environmental factors. Faculty of 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 emphasize that drug therapy is not the only solution: psychotherapy will continue to be a valuable and useful form of treatment for sexual dysfunctions – even for those people whose condition is rooted in a genetic cause. The study by Pekka Santtila, Kenneth Sandnabba and Patrick Jern was published in the Journal of Sex & Marital Therapy in March 2009. For more information, please refer to the source article .
