Professor Morten Frisch explained that these results were surprising

At Ukmedix News we recently published a study which showed that men who are overweight were likely to have problems with sex. The same study which was done by the Staten Serum Institute in Copenhagen, Denmark also looked at female sexual problems and showed that being underweight or overweight actually improved the chances of women having a normal sex life.

These research results which should be approached with a little bit of caution showed that underweight women reduced the likelihood of having problems with sex by 50 percent and that obese women had a 70 percent smaller chance of sexual dysfunction when they were both compared to normal weight women.

Professor Morten Frisch explained that these results were surprising and may have been down to the fact that many women who have weight problems give up sex altogether, so that the results did not really reflect the true situation. It seems crazy that being underweight or obese could improve sex for women but that is what the figures seem to show.

The sexual problems which were reported included vaginal dryness, the inability to achieve orgasm, pain when having sexual intercourse and vaginismus which is when women have involuntary spasms that tighten the vagina making intercourse difficult.

Another interesting finding was that women who were very athletic were over four times more likely to experience vaginismus when compared to women who did not exercise much. It could be that those women who exercised had much stronger vaginal muscles which made the vaginismus more of a problem.

Other findings were that the women who did not exercise were almost 50 percent more likely to be sexually inactive compared to those women who got some form of regular light exercise. Women who smoked, who did not drink alcohol, who had a body mass index of more than 30 or a waist of over 34 inches were also more likely to be sexually inactive.
