Does Vagina Size Matter?

By Tammy Worth
WebMD Feature
Reviewed by Laura J. Martin, MD

The age-old question of whether or not size matters is typically directed at men, but this is a somewhat hidden concern for women as well.

Though they might not talk about it, some women may worry about the size of their vagina and how it affects sexual pleasure, particularly after having a baby. Not a lot of research has been done in this area and because there are so many variables at play in women’s sexuality it is difficult to tell if vagina size and sexual pleasure are linked.

How to Protect Yourself From A Stalker

By Maura Kelly Recently, a new show called Stalked: Someone's Watching, premiered on the Investigation Discovery channel. Over the course of six episodes, the program recounts the stories of men who relentlessly pursued former partners, or neighbors, or relative strangers - and provides some insight into their twisted motives. The first episode details the relationship between Peggy Klinke and Patrick Kennedy, the man whom she once considered the love of her life - who would eventually kill...

“Our ability to understand size as it relates to sexual function is poorly understood,” Christopher Tarnay, MD, director of the division of female pelvic medicine and reconstructive surgery at the UCLA Medical Center, tells WebMD. “But in the last 10 to 15 years, there has been a lot more attention paid to the field of sexual medicine.”

Accommodating and Changeable

The vagina is a very “elastic” organ, says Christine O’Connor, MD, director of adolescent gynecology and well women care at Mercy Medical Center in Baltimore. It is small enough to hold a tampon in place, but can expand enough to pass a child through. This is because the walls of the vagina are similar to those of the stomach, they have rugae, meaning they fold together to collapse when unused, then expand when necessary.

“It doesn’t stay one particular size,” O’Connor says. “It changes to accommodate whatever is going on at that time.”

The most commonly used measurements regarding the size of vaginas come from Masters and Johnson’s work from the 1960s. They looked at 100 women who had never been pregnant and found that vagina lengths, unstimulated, range from 2.75 inches to about 3¼ inches. When a woman is aroused, it increased to 4.25 inches to 4.75 inches. Regardless of how long the vagina is, the area that is thought to be important for most women’s sexual response is the outer one-third.

So how does length relate to sexual satisfaction? No one seems to know for sure.
