Study looked at dopamine, a chemical in the brain(CANVAS STAFF REPORTS) - Long linked to psychological issues, scientists now believe premature ejaculation could be inherited, reports the Daily Mail .
The study suggests the problem may be passed down through the generations. The condition affects one in four men in the United Kingdom, reports the news site.
The researchers in Sweden and Finland have found that a genetic abnormality can affect levels of a chemical in the brain. Specifically, they found that men in their study carried a defect in a gene that controls the release of dopamine. The chemical acts like a neurotransmitter and plays a crucial role in important activities including movement, attention span and the brain's perception of pleasure and reward.
Scientists now say premature ejaculation problems could be treated with drugs that boost dopamine levels in the brain. The researchers noted that for decades dopamine-based drugs used to treat Parkinson's disease had an aphrodisiac effect on some patients, reports the Daily Mail.
The study involved nearly 1,300 men ages 18 to 45. They were each asked how long they were usually able to last during sex. Researchers also took saliva samples to test for defects in a dopamine transporter gene, called DAT1.
Most experts have believed that an inability to relax during sex was among the psychological issues that cause premature ejaculation. Doctors can treat the condition with relaxation techniques and sometimes with anti-depressants to control anxiety.
The study was published in the Journal of Sexual Medicine .
The Mayo Clinic says an estimated one in three men are affected by the condition at some time. One solution is better communication, according to the clinic.
"In some cases, premature ejaculation may be caused by poor communication between partners or a lack of understanding of the differences between male and female sexual functioning," states the clinic's website
