7 Vagina Studies That Will Seriously Freak You Out

There are many people in the world who have vaginas, and this is a fact. You know this. I know this. We all, I would think, know this to some extent. So, considering how many vaginas there are in the world (floating around and creating mischief, as vaginas are wont to do) (JK), it is surprising, then, how little most people know about them. If you have a vagina, you’re probably a little freaked out by your own flaps and folds, and, when it comes to straight guys who don’t have vaginas, you can pretty much be assured that they don’t know anything about it.

But all of that is about to change–well, for you at least. There has been lots of interesting research and studies done on vaginas in recent years, and, whether you are a vagina-haver or not, you’re probably going to want to take a look at them. So, check out these (cool) studies on vaginas that will probably also freak you out a little bit:

Your Vagina Has More In Common With Sharks Than You Think

I mean, I don't know. Maybe you have always considered your vagina to be a little bit of a shark? It's very possible! But, as it turns out, pretty much everyone who has a vagina has something in common with sharks, because a compound that is found in natural vaginal lubrication, squalane, is also found in sharks.

Menstrual Blood Has A Lot Of Health Properties

Menstrual blood contains a surprising amount of stem cells, which are cells have the ability to "regenerate" other cells in the human body. This doesn't mean that you should start drinking the contents of your DivaCup now (although I recently found some blogs that discuss doing just that, which I will NOT be linking to!!!), but what it does mean is that elements of menstrual blood might soon be present in some of your medications. New research, for instance, indicates that these stem cells can be used to help people with heart failure.

Vaginal Bacteria Can Affect Herpes And Zika Virus Transmission

The vagina naturally contains a lot of bacteria, called a microbiome. And, according to some new research done at the University of Texas Medical Branch at Galveston, a certain amount of this bacteria could actually limit infection from diseases like herpes and Zika virus. This is because this type of bacteria, Lactobacillus, changed the expression of the genes in invasive diseases like herpes and Zika, making it harder for them to be transmitted. This is a preliminary study--meaning it hasn't been published in an official peer-reviewed journal yet--but it's cool to know that vaginal bacteria could potentially help stave off disease.

Your Clitoris Has More Nerve Endings Than Anywhere Else On The Body

The clitoris contains about 8,000 nerve endings, which is more than the amount of nerve endings on any other part of the body. (It's also double the amount of nerve endings on the glans of the penis, for what it's worth.) IS this a bad thing? Not in the slightest! It just means that it's sensitive down there, and you should treat it as such.

It's Possible To Have Two Vaginas

Yes, really. It's uncommon, but there is a condition called "uterus didelphys," which means that you have two uteruses, two cervixes, and/or two vaginas. This condition usually has no symptoms, and is usually realized by a doctor during a regular pelvic exam or by a woman who realizes that the insertion of a tampon isn't stopping her period (because, you know, only one vagina is being stopped up). This condition doesn't stop women from having a healthy and normal sex life, but it can cause issues with the kidneys, miscarriage, and infertility.

It's Possible For A Penis To Get Stuck In A Vagina

This, called "penis captivus," is another rare, but possible, vaginal occurrence. Basically, when the vagina contracts during sex, it can trap a penis (or whatever else is inside of it) through its contractions. Again, this is super uncommon, and, if it does happen, it pretty much only lasts a few seconds. So you don't really have anything to worry about. But, hey--the more you know, and all that.

You Don't Always See All Of Your Clitoris

When you think of your clitoris, you probably picture a small, button-like nub. But this is actually only part of the picture--most doctors say that that the clitoris has "branches" that extend into the vagina for about three inches. This means that you can think of your clitoris as a tree or a wishbone, rather than a dot. (I mean, you don't have to think of it in any way at all, really. But you can!)
