Female vagina and 11 interesting facts about it (can fart, you know!)

How well do you know about a woman's vagina - beyond what you know about its function as a sex organ and a baby's birth canal? Although it is often a topic of conversation in whispered neighbors, the basic knowledge that we have about the vagina is still far from sufficient. For example, did you know that the word "vagina" comes from the ancient Latin meaning "scabbard"?

There are so many strange, interesting, and even shocking facts about a woman's vagina that you never thought before. Here are 11 of them.

Did you know that that woman's vagina …

1. Has thousands of nerve endings which are far more than the penis

There are 8,000 nerve endings in the clitoris (the "little button" between the lips of the vagina), while the penis has only 4,000. This is why the clitoris is considered the most sensitive part of the female erogenous zone. The strong sensation of stimulation in the clitoris can spread to the pelvic area of women by affecting the other 15,000 nerve endings.

2. Have something in common with sharks

The vagina of women and sharks both contain a substance called squalene. Squalene is found in shark liver which is commonly extracted for the production of shark liver oil. Meanwhile, squalene in the vagina acts as a natural lubricant when a woman is "wet".

3. Can expand during sex

The vaginal opening is usually about 3 cm in diameter. But the vagina can stretch up THREE TIMES the size of the original width, and from an average length (depth) of 7 or 8 cm so that it can extend to 10 or 11 cm. This is because the muscle tissue around the vagina is so flexible that it can naturally stretch and return to its original shape. That is why having sex repeatedly will not make the vagina stretch, as the myth says that circulating. And not only stretched wide, a woman's vagina can lengthen as long as aroused.

This ability of a woman's vagina to fluctuate is also useful during labor to allow them to push out the baby they are carrying.

4. Have lots of G-spots

Many think there is only one G-spot. But Malaysian sex scientist Chua Chee Ann, MD, has identified another possible area called the A-spot (or the Forital Anterior Fornix Erotica zone). He revealed that the A-spot is a few inches above the G-spot, along the abdominal side of the vaginal wall. Other studies say that there are actually many other pleasure points in the vagina.

5. Has a distinct smell

Each vagina has a distinctive odor, which varies from person to person. But a normal, healthy vaginal odor shouldn't smell like flowers or fruit.

There are many reasons why one woman's vagina smells different from another woman's. Some of the reasons include: the food he consumes, how good his personal hygiene is, how much he sweats, what you wear, etc. However, basically the vagina gives off a slightly sour smell like vinegar. This scent can even be smelled from a distance of about 30 centimeters away.

6. Can fart

Farts not only come out through the back, but can also pass through your vagina. This is called queefing. Queefing is when air is trapped in the vaginal canal and the vagina blows it back out, therefore a fart-like noise comes out. Fortunately, queef is odorless.

The vagina is not shaped like a straight tube but is wavy and wrinkled, making it easier for air to get trapped in the vagina. Queef also usually occurs due to weakening of the vaginal and pelvic muscles.

7. Very strong

"The resistance of the vaginal muscles is very strong," said Alyssa Dweck, M.D, quoted from Women's Health. What is meant by muscle endurance here is the condition of the muscles in a still state but a little tense and ready for action. Even so strong was the endurance of the vaginal muscles, that a woman broke the weight-lifting record in 2009 by lifting weights of more than 30 kilograms using only her vagina.

The vagina is even strong enough to trap the penis inside. This is known as the captivus penis, aka gancet death. Pinching death is a rare occurrence during penis-vaginal penetration when the muscles in the vagina clamp down on the penis tightly, thus preventing the penis from withdrawing from the vagina.

8. Can collapse

Maybe you are familiar with the term hernia or descending bero. Now, a vaginal collapse is similar to this, called utero-vaginal prolapse. Utero-vaginal prolapse causes the vagina, or uterus and vagina, to fall so that it protrudes outside the body. This can occur after childbirth or after menopause due to a lack of pelvic support, but it is rare and can be corrected with surgery.

9. Have the same acidity (pH) as tomatoes

A woman's vagina has a pH of about 4 (normal pH range ranges from 3.8 to 4.5). This figure is equivalent to a glass of red wine or one tomato. This acidity is useful for maintaining the balance of the ecosystem in the vagina. So it's best to avoid it when using certain hygiene products, which can actually upset the balance and create unwanted irritation.

10. Can clean yourself

While men may need to clean their penis regularly to prevent the buildup of smegma that can lead to yeast and bacterial infections, the vagina has an automatic self-cleaning system. The vagina will produce natural fluids to clean bad bacteria and maintain a healthy pH. That's why you shouldn't - and shouldn't - douche. When washing the vagina, it's best to avoid scented soaps, gels, and antiseptics, as all of these can affect the healthy balance of bacteria and pH levels, and even cause irritation.

11. Menstrual blood can be used as a medicine for heart failure

Currently, a clinical trial is in phase II testing the safety of ERCs (endometrial regenerative cells), aka "stem cells", for treating patients with congestive heart failure.

The process is like this: stem cells are taken from menstrual blood samples and then cultured in the lab to produce various types of new cells in the body. In this case, the stem cells are made into heart muscle cells, for reparative purposes in heart failure patients. This is an unfamiliar experimental study, and not something that's being done routinely, but yes, the result is that menstrual blood can help patients suffering from heart failure.
