VAGINAL SIZE AND SEXUAL FUNCTION

An article in the medical journal, Obstetrics and Gynecology, shows that a woman's sexual function has little to do with vaginal size, vaginal muscle strength or vaginal tissue thickness.

One hundred and four women filled out a questionnaire assessing sexual function and were measured for vaginal length, lining thickness and muscle strength. There was no relation between these measurements and sexual desire, frequency of sexual relations, vaginal dryness or pain on intercourse. Previous studies show that sexual desire in women is related to blood levels of the male hormone, testosterone. Women with low levels (below 30 nannograms) have significantly decreased desire, while female athletes who take synthetic male hormones to make themselves stronger often have ravenous sexual appetites. Women with decreased sexual desire who are healthy and in a healthy relationship can be treated with injections of 100 mg of testosterone enanthate every three weeks for several weeks.

Forty per cent of women in the study suffered from pain on intercourse or vaginal dryness. The most common causes are vaginal infections and inadequate foreplay, which can be treated with appropriate antibiotics and patience.

Just as this study shows that vaginal size, tissue thickness and muscle strength are not related to sexual satisfaction, many previous studies show that penile size is not related to sexual satisfaction.
