Comparison of Vaginal Shapes in Afro-American, Caucasian and Hispanic Women as Seen with Vinyl Polysiloxane Casting

Paula B. Pendergrass Cornelia A. Reeves Meyer W. Belovicz Darron J. Molter Janet H. White

Abstract

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.

[. . .]

In addition to the three molds, vaginal length and introital distensibility were obtained. With the subject in the supine position, length was taken by having the subject insert a 7-inch polished acrylic rod as far back into her vagina as possible without causing discomfort; introital distensibility was determined by having the subject insert a lubricated 125-ml polypropylene Erlenmeyer flask as far back as possible into her vagina without causing discomfort. The circumference at the point of entry was marked and measured, and a diameter was calculated.

[. . .]

Comparisons of the length of anterior and posterior cast walls as measured with calipers for all three study groups are given in table 2. For the posterior measurements, Hispanics showed a much narrower range than either Afro-Americans or Caucasians, and, importantly, they exhibited no posterior lengths less than 8 cm. Consequently the mean for Hispanic casts was significantly greater (p = 0.01). The mean anterior length for Hispanics was also significantly different (p = 0.01) but was shorter than those of the Afro-Americans and Caucasians. Consequently, the overall picture of the Hispanic cast is one that is relatively short along the anterior wall, but considerably longer along the posterior wall. The longer posterior measurements are reflected in deeper posterior fornices among the Hispanic subjects which, interestingly, all showed a full cervical imprint in the cast; this suggests that the cervix in Hispanics consistently lies in a deeper position within the vaginal vault.

Comparisons of the length of anterior and posterior cast walls as measured with strings for all three study groups are shown in table 3. These measurements directly reflect the caliper measurements. Hispanic casts are significantly longer posteriorly (p = 0.01) and shorter anteriorly (p = 0.01), with anterior lengths being shifted downward 1–1.5 cm.

Maximum widths (side-to-side) and depths (anteriorposterior) are given in table 4. Hispanic casts are significantly wider than either Afro-American or Caucasian casts (p = 0.01), with the mean being over 2 cm greater than Caucasians, and over 1 cm greater than Afro-Americans. Also, the range of widths is noticeably narrower among Hispanics indicating a more homogeneous group.

The mean depth is somewhat greater among Hispanics but is not significantly different from that of Afro-Americans and Caucasians. The variability among Hispanics is smaller with a narrower range and a smaller standard deviation.

Average rod lengths for Caucasians and Afro-Americans were 11.51 and 11.18 cm, respectively, and introital diameters were 4.66 and 3.14 cm, respectively. Both measurements were significantly different as measured by t test (table 5). Because rod and introital measurements were obtained from only 5 Hispanic subjects, no statistical comparisons can be made. Hispanic rod lengths ranged from 8.2 to 12.5 cm, and the introital measurements ranged from 1.9 to 3.2 cm.

A summary of t tests for comparison of Caucasian, Afro-American and Hispanic subjects is presented in table 5. These results show statistically significant differences among the three groups in the following areas: (1) the posterior cast length as measured with both calipers and strings is significantly longer for Hispanics than for Caucasians and Afro-Americans; (2) the anterior cast length as measured with both calipers and strings is significantly shorter for Hispanics than for Caucasians and Afro-Americans; (3) the width of casts in the lying position is significantly greater for Hispanics than for Caucasians and Afro-Americans; (4) the Caucasian introitus is significantly greater than that of the Afro-American. From this we conclude that there are differing distributions of shapes and much greater homogeneity among Hispanics than among Afro-Americans or Caucasians.

Trivial, perhaps, but these things add up. Racial differences exist, but--contrary to the impression one might get reading REB--they don't always neatly align with Rushton's "r-K" framework. Much of his work has value, but Rushton is far from infallible.

Previously, I've taken issue with some of Rushton's claims concerning testosterone (low in sub-Saharan Africans compared to Westerners; minimal black-white differences in America; hardly a good candidate to explain black social pathology), fundamental vocal frequency, penis size (what evidence exists suggests minimal black-white differences), and testis mass (greater in whites compared to Asians and blacks, according to the available autopsy studies).

In all seriousness, do you think this plays any part with white women having this mandingoish yearning for the the feral negro? Or do you think it is due more to the incessant indoctrination by the MSM?

One thing that is certain in my mind; never underestimate the depravity a white woman will go to in order to satiate that "XL" hole of hers. Always looking to "outwhore" one another. Sickening.

Dude, are you white, off-white, or non-white?

If (1) I suggest you put down the porn and go interact with actual women.

"Dude", I'm white and have you ever heard of "girls gone wild"? Pretty pathetic example of our young women, if you ask me. Not to mention, that bit of white depravity made some Jew, filthy rich. What else is new?

I also do not appreciate your unfounded tone. Living in a major metropolis, one sees white women with blacks way too often. Where do you live that you are spared this hideous site, Mayberry?

Anonymous said...

(1) "Girls gone wild" is not a representative cross-section of white womanhood. Do I really need to tell you this?

(2) White women do not have a "yearning for the the feral negro". Nowhere do they pair with blacks at rates approaching what you'd expect if they chose randomly with respect to race--much less show a preference in favor of blacks.

(3) When members of different races live in close proximity under modern conditions, some will mix. Period. MTV may increase the tendency; social controls may lessen it. Regardless, the actions of 1-10% of women should not cause you to write off the other 90-99%. Shun those who need shunning and go on with your life.

(4) White women like sex. Women of all races like sex. The idea that white women are particularly depraved (relative to whom?) is simply bizarre. Women will tend to behave as they're expected to behave (at least within certain broad natural limits). Tell them they're supposed to act slutty in public during college and some of them (still a small minority) will.

If your first post was genuinely "in all seriousness":

(5) The average white woman doesn't have an "XL hole". The diameters are the maximum they could accommodate "without discomfort".

(6) Women do not, in the overwhelming majority of cases, choose partners based on penis size.

If anything black women are depraved. I lived in a while in a majority black area (laid off, so my budget was limited for a while) they have litters of children, and have sex like most people drink water. Most white women would never date a black man and with good reason. Unless you are looking to have an illegitimate child and contract HIV.

Man's nature is corrupted, and he is thus totally unable to please God. Every man is in need of regeneration and renewal by the Holy Spirit through Christ Jesus. He lived a sinless life and voluntarily atoned for the sins of men by dying on the cross as their substitute, thus satisfying divine justice and accomplishing salvation for all who trust in Him alone. Jesus Christ will come again to the earth - personally, visibly and bodily - to consummate history and the eternal plan of God.

Jesus is the way, the truth, and the life.

(John 3:16-17)

This study is flawed.
"Black rates of drug and alcohol abuse are higher."

There is no difference in drug abuse between blacks and whites.

Blacks are statistically more likely than the national average to be abstainers from alcohol, that is, during a give period of time, they have a greater than average likelihood of not consuming any alcohol at all.

I wonder how many 14 yr old boys are on this site wondering about the vaginal size and shape of various ethnic groups. It appears that all of the commenters so far are of this group. I was looking to see the difference due to some personal experiences that I had.

Probably none.

If you are racist against blacks, I would think you would want to see black men with white women as this pairing would not result in "black" children.

White women have XL HOLES. Lol lol. My uncle said that and I'm lmao. And that's why they run after the black man. I mean they run them down. Trying to satisfy that big XL HOLE. Hahaha lmao.

Anonymous said...

The abstract paragraph says that "Afro-American women" were used in the study. That means that all of those women were born in Africa, immigrated to the U.S., and became U.S. citizens. It doesn't say that all of those women were black. 3% of South Africans have ancestors who came from India. If one of those people becomes a U.S. citizen, he or she is an African-American.

I love black girls they have the best and I'm white haha I guess I got tired of dealing with XL holes

What a shitty comment thread. Let me shit it up some more. Interesting post, though.

Did you degenerates not read the study?

Hispanic women had the widest vaginal casts (with less variation) of the three groups, then black women, then white. Black women, however, did have a significantly smaller introitus (opening), which is most definitely related to the smaller skull size of black infants.

Black pussy is tighter. Look up prolapse porn and you won't see any black women because this rarely happens to them. I've dated women of all races and can confirm black women just hold up better.

My experience is that Latinas do have wider deeper pussies. My wife is Latina and her vagina feels a lot different than my Caucasian ex girlfriends. She is very soft, wet and deep. In my opinion this is fantastic. I can last a lot longer before I orgasm and we spend lots of time in bed enjoying each other. This isn’t to say that I didn’t enjoy sex with my former lovers. This is a very interesting study. I wouldn’t have guessed there were physical differences in vaginas between races.

I'm a white male who has dated white, black, Asian, Pacific islander, and Hispanic. From a purely subjective perspective, black women are the tightest, and have the best shape of vagina.

My wife is black. The shape of her vagina had nothing to do with me falling in love with her. But it might explain us having three babies within five years!

Western white women do have pussy holes that open up very big it's sad really because most of these white girls don't take care of their children or their bodies some go for months without taking a shower or bath basically white girls are just cum dumpsters because they can't do anything else but pop out children and have sex with dogs or other none human animals such as horses donkeys ect truthfully they really need to get professional help it's a sickness

Unknown said...

Wow, that's a stereotype

Unknown said...

From my experience, white women had the widest pussy, and latinas that were mestizas had extremely tight pussy, my ex gf was one of those and it felt like I was fucking a virgin just after a week of not having sex.

Hello friends,
I'm a little ashamed to tell such a story. But I would like to share with you a great resource. I've had problems since my sexual organ was too small. I've been worried about this and tried to rectify the situation by means of pumps and tablets. Because of the tablets, which I ordered, I had complications and I was in the hospital for some time after that I gave up trying to increase my penis. But once I found Dr adam herbal cream. My first result was: plus 3 centimeters after 2weeks of usage. If you want to know more details and how you can enlarge your penis bigger, I recommend you to contact Dr adam today, email address adamokpoko@gmail.com or add him on whatsapp line +2348151731392.
