"Girls snap more times, the bottom will become loose, and it will turn black!"
"After girls go to the toilet, they can't wipe it with paper, otherwise they are prone to genital inflammation!"
You've heard all of these statements, right?
Attention! It's all rumors!
Today, Zhimei specially came to debunk the rumors and swept away the 6 rumors about the girls' private parts!
1
A woman's private parts are, from front to back, the urethra, the vagina, and the anus.
Compared with men, women's urethra is short and straight, and they are more likely to develop urethritis.

However, urethritis is most commonly sexually transmitted, followed by urethral injury, foreign bodies in the urethra, urethral obstruction, and inflammation of adjacent organs [1].
There are three main types of vaginitis: bacterial vaginitis, trichomoniasis vaginitis, and fungal vaginitis.
These 4 common causes of inflammation in girls' private parts can be found in the following table [2], focusing on the transmission route, and beware of Oh ~ in life
Toilet paper, it doesn't matter what kind of genital inflammation it is!
Of course, in order to avoid the occurrence of small probability events, we recommend that girls wipe their farts like this: from front to back, urethral vaginal anus.
This operation is not mandatory, as long as the toilet paper is clean and hygienic.
In order to reduce irritation to the private parts, it is best not to use scented toilet paper.

Vaginal laxity and loss of elasticity are due to the muscles being stretched for a long time, and over time they become loose, and the vagina will become wider. There are three main types of reasons:
Pregnancy gives birth
Prolonged time (October pregnancy), as well as hormone boosting (late pregnancy relaxin dilates the birth canal), can lead to vaginal laxity. Therefore, new mothers generally have pelvic floor training after childbirth to help with rehabilitation [3].
age
In addition to engraving marks on the face, the years will also cause muscle strength to decrease, and the vaginal mucosa will atrophy, aggravating vaginal laxity.
Other reasons
Constipation, obesity, pelvic floor trauma, pelvic floor surgery history, long-term chronic cough, etc.
3
Estrogen, in particular, promotes melanin production. When a woman enters pregnancy, melanocytes also increase production, and there is significant pigmentation in the nipple and perineum.
As your baby is born, hormones gradually recover and pigments subside naturally.
In the same way, there will be obvious skin color changes in the private parts before and after menstruation.
With age, estrogen and progesterone continue to decline, and the increased production effect on melanocytes gradually disappears. As a result, the skin color of the private parts of older women gradually becomes lighter [4].
In addition, the color of the private parts is also related to the innate inheritance.

The vagina has a self-purifying function [5], relying on the original normal flora balance.
Indiscriminate drug flushing may kill beneficial bacteria, change the original acidic environment, make those "bad bacteria" out of control, and even increase the risk of vaginitis [6].
Girls only need to wash the vulva with warm or running water when bathing every day.
Remember not to do your own intravaginal irrigation at any time, including during menstruation or before and after sex, and there is no need to use any lotions or "skin care products".
Even for people with vaginitis, if it is not the doctor's symptomatic medication, they only need to clean the vulva with warm water every day. Don't buy your own medicine to clean.

In fact, more than 50% of women do not bleed during and after their first vaginal intercourse [7].
If there is bleeding, it is normal, because the hymen of the vaginal opening (also known as the vaginal flap) is fragile, easy to rupture during the first sexual relationship, and a small amount of bleeding.
If there is no bleeding, it is normal. The hymen is very fragile, and strenuous exercise (such as cycling) or falls, bumps, etc., can cause the hymen to rupture.
After the rupture, not everyone will have pain and bleeding; it may also be that there is less bleeding at that time, and the girl herself is not aware of it.
6
Let's correct one idea:
The hymen is not simply a membrane, but an elastic circular mucosal fold with an opening in the center that allows menstrual blood to flow out of the body. The size of the hole varies from person to person, generally about 2.5 cm in diameter.
(Source: Self-drawn [8])
The diameter of the internal tampon is generally 1.32-1.42 cm, which is more than enough through the hymen and will not damage it.
Studies have also shown that for women with no sexual experience, the appearance and structure of hymens do not change with the use of tampons or sanitary napkins [9].
Many girls are ashamed of sex and private parts, making private health a knowledge blind spot.
Rumors breed panic, take root in the heart, and unconsciously become "common sense" that harms people.
Forward this article to good sisters, and don't be deceived again!
