Do black women really have the tightest vagina's?

OBJECTIVES

To use static and dynamic magnetic resonance imaging (MRI) to compare dimensions of the bony pelvis and soft tissue structures in a sample of African-American and white women.
METHODS

This study used data from 234 participants in the Childbirth and Pelvic Symptoms Imaging Study, a cohort study of 104 primiparous women with an obstetric anal sphincter tear, 94 who delivered vaginally without a recognized anal sphincter tear and 36 who underwent by cesarean delivery without labor. Race was self-reported. At 6–12 months postpartum, rapid acquisition T2-weighted pelvic MRIs were obtained. Bony and soft tissue dimensions were measured and compared between white and African-American participants using analysis of variance, while controlling for delivery type and age.
RESULTS

The pelvic inlet was wider among 178 white women than 56 African-American women (10.7±0.7 cm compared with 10.0.±0.7 cm, P<.001). The outlet was also wider (mean intertuberous diameter 12.3±1.0 cm compared with 11.8±0.9 cm, P<.001). There were no significant differences between racial groups in interspinous diameter, angle of the subpubic arch, anteroposterior conjugate, levator thickness, or levator hiatus. In addition, among women who delivered vaginally without a sphincter tear, African-American women had more pelvic floor mobility than white women. This difference was not observed among women who had sustained an obstetric sphincter tear.

Full vinyl polysiloxane casts of the vagina were obtained from 23 Afro-American, 39 Caucasian and 15 Hispanic women in lying, sitting and standing positions. A new shape, the pumpkin seed, was found in 40% of Afro-American women, but not in Caucasians or Hispanics. Analyses of cast and introital measurements revealed: (1) posterior cast length is significantly longer, anterior cast length is significantly shorter and cast width is significantly larger in Hispanics than in the other two groups and (2) the Caucasian introitus is significantly greater than that of the Afro-American subject.

I think torso length and hip width are pretty good determiners for vagina size. It is not the height of of the women (head to foot) which determines the depth of the vagina.
There is definitely a racial difference and also genetic factors which determine the length of vagina. White women give birth to babies with larger heads "on average" so their hips are "on average" broader, and their vaginal opening is also larger. Black women, actually have smaller vagina's. They give birth to babies with smaller heads and have smaller hips. Black women store more body fat on their buttocks, but their hips are actually smaller (men and women). White people also have longer torso's and white women also have longer vagina's. Asian women have shorter vagina's than both black and white women, have wider openings than black women, but not as large as white women. Unlike penis size, the body size/shape of a woman has an influence on vaginal size. Taller women (longer torso) with wider hips will most likely have longer and deeper set vagina. Torso size/length is more significant than actual height. As for men however, a 6' 8" man may have a smaller penis than a 5' 8" man, just like has ears may also be smaller. External organs are not influenced by body size or height, whereas internal organs are.


Penis length among different races of men DOES NOT directly equate to vagina size and distance to the cervix in the same race of women.

Hip, pelvic, and vagina size also more strongly corresponds to height. Taller women often have larger hips and vaginas. Where there is not as a direct correlation to height and penis size among men.

Penis size among men, is more like breast size among women. Very tall women can have small breasts and short women can have large breasts. Just like small men can have a large penis, while tall men can have a short penis.

White and Asian women have the tendency to have more broad hips than many groups of Black women.

The tendency of Black women to have more narrower hips is also partially why Black women are faster sprinters. Black women "compensate" by having tilted hips. The hip tilt is also why Black women have rounder butts.

Asian women, in proportion to their size, have the broadest hips. While White women, factoring in taller heights, would have the broadest hips.

This means that tall White and Asian women would have greater pelvic space and LARGER vaginas than Black women on average.

As to why Black males would have larger penises, it is argued that their proportions are because they are from hotter climates. People in hotter climates have smaller torsos and longer legs. People in colder climates have longer torso and shorter legs. More of the penis would be exposed, with the shorter torso. It is argued that this and other small adaptations help Blacks throw off extra body heat.

Males from colder climates, like Asians and Whites, would have the penis closer to the body to keep it warmer.


I've always heard people say Asian women do, but research and gynecologist are saying black women do?
