A recent research by researchers at the Utrecht University revealed that genes determine the rapidity of ejaculation in men. This research was done by Neuropsychiatrist Dr Marcel Waldinger and Pharmacological Researcher Paddy Janssen.

Under the study, researchers analyzed the data collected from 89 Dutch men who suffer from the primary form of premature ejaculation. This data was compared with the data collected from a control group of 92 men. In this study, the female partners used a stopwatch at home to measure the time until ejaculation each time they had intercourse for a month. Analysis of data showed that in men who suffer from premature ejaculation, the substance serotonin was less active between the nerves in the section of the brain that controls the ejaculation. Researchers found hand of a gene behind premature ejaculation. This gene known as 5-HTTLPR, had already been discovered. This gene appeared to be responsible for the amount and activity of serotonin, which meant that it controlled the rapidity of ejaculation. 

Earlier studies have shown that three types of the gene exist: LL, SL and SS. The recent study showed that the LL type causes a more rapid ejaculation. Analysis of data showed that on average, men with LL ejaculate twice as quickly as men with SS, and also almost twice as quickly as men with SL. 

Waldinger said that this study applies to men who have always ejaculated prematurely from their first sexual contact onwards and not for men who started suffering from this later on in life.

He added that this theory contradicts the idea, which has been common for years, that the primary form of premature ejaculation is actually a psychological disorder.
