Premature ejaculation not caused by nerves
Premature ejaculation appears to be strongly linked to genetic factors and is not just psychological, researchers in Finland found.
Pekka Santtila, Kenneth Sandnabba and Patrick Jern of Aringbo Akademi University in 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 and premature ejaculation at their first sexual encounter.
Such common problems are often attributed to external factors, such as intoxication or nervousness, but the research confirms such factors do cause erectile dysfunction but not premature ejaculation.
The study, published in the Journal of Sex & Marital Therapy, said premature ejaculation appears to be strongly linked to genetic factors, not environmental factors.
