Studies Show Orgasm Difficulties Partially Genetic

Scoop Report: Studies Show Orgasm Difficulties Partially Congenital

By Marietta Gross – Scoop Media Auckland.

Scientists have found the reason why some women have difficulty reaching an orgasm is due to genetics. That’s the result of a study by the Twin Research Unit of the St. Thomas’ Hospitalwww.guysandstthomas.nhs.uk.

Studies of 4000 twins showed that a woman’s ability to reach an orgasm was not necessarily as a consequence of psycho-social circumstances as some might suppose and that critical genes could play an important role for the development of drugs for the stimulation of an orgasm.

The results of the study were published in the Biology Letters http://pubs.royalsoc.ac.uk/biol_lett.

According to the BBC the results suggest women who easily reach an orgasm were more easily satisfied with partners who were not such good lovers.

Scientist Tim Spector and his colleagues arranged DNA-tests with more than 4000 women between the age of 19 and 83 years. One half of the participants were monozygotic, the other half were fraternal twins. Identical twins have the same DNA, fraternal ones not.

The women were asked to fill in confidential questionnaires about their sex lives.

A third of the women said they seldom or never reached an orgasm.

More than a tenth said they always climaxed due to sexual intercourse.

And 34 percent of women reached orgasm through masturbation.

Studies with men have shown that only in two per cent of cases of coitus no orgasm was reached. In total the orgasm frequency was higher within identical twins.

Tim Spector said: “We have proven that 34 to 45 per cent of the variations within the ability to reach a climax can be explained by genetic variations. There is a biological impact which cannot be traced back to education, religion or race. The heritability suggests that evolution plays a role.”

One theory assumes that an orgasm supports fertility. Studies show that women find it easier to reach an orgasm during their fertile days, and, that sperm absorption during the orgasm is increased.

Tim Spector said another theory suggests that the orgasm was a trigger for women to choose more attractive male partners.
