Scientists have proven that the main cause of premature ejaculation in men is genetic predisposition.
Premature ejaculation is typically common among young and inexperienced lovers, writes sexyweek.ru. Ejaculation can occur even before or immediately after penetration. This can be uncomfortable for both partners. A very short intercourse is the most common cause of lack of orgasm in women.
Previously, scientists believed that physiological and psychological factors were the cause. Swedish scientists, along with their Finnish colleagues, discovered that the cause lies in men's genes. Research has shown that men with defects in the genes that regulate dopamine levels are much more likely to experience sexual dysfunction. Experts believe that medications that increase dopamine levels in the brain can help men prolong their pleasure and achieve orgasm in their partners.
