Vagina and urethra?

The position of vagina refers to the distance between vagina and vulva relative to anus. Generally speaking, the distance between vagina and anus is less than 2 cm, which is called vaginal low position, and the distance is greater than 4 cm, which is the median position. According to medical data. 80% of female vagina belongs to the middle position (the distance between anus and vagina is 2 ~ 3.5cm), but the high and low positions are less, accounting for about 10% respectively.

Not only the vagina and vulva are close to the anus, but also the vaginal opening is backward, which is more prone to uterine retroversion. At this time, because the uterine body is backward, the cervix will tilt forward and their vaginal opening will be relatively backward, so the chance of pregnancy will be reduced. Low vaginal position also has an impact on sexual life, and it is easy to have backache, and the traditional sexual intercourse position will cause pain. Clinical data show that most patients with endometriosis have low vaginal position. The more suitable coital position for people with low vagina is supine position, which can avoid coital pain.

The vagina and vaginal orifice of the person with high vagina are forward, close to urethra, far from anus, and the uterus leans forward, so the probability of pregnancy is higher. According to the survey, women with high vagina are easy to accept the stimulation of clitoris and vagina in sexual life, so they are more likely to feel orgasm.

Of course, if you want to know the exact location of the vagina, in addition to self-test, it is best for professional obstetricians and gynecologists to make judgments from the perspective of vagina through internal diagnosis. In order to avoid pain during sexual intercourse, people with low vagina can raise their arms when choosing other positions, which can not only eliminate pain, but also be good for pregnancy.

Distinguish:

Female external reproductive organs, also known as vulva, include pubic mound, labia majora, labia minora, clitoris, vestibule, anterior chamber gland, urethral orifice, hymen and perineum.

Yin Fu: The vulva before pubic symphysis. The pubic hair on adult women's skin is inverted triangle (diamond for men). The density and color of pubic hair vary from person to person or race.

Labia majora: It is a pair of wrinkled skin walls on both sides of vulva. There are pubic hair on the side, a lot of fat and elastic fibers under the skin, and abundant venous plexus. The trauma of labia majora caused by various reasons is easy to form hematoma. The labia majora, which has experienced childbirth, has been separated; After menopause, labia majora atrophy.

Labial labia minora: Located on the inner side of labia majora, it is a pair of mucosal fold walls, soft, without subcutaneous fat, rich in sebaceous glands and sweat glands, and its surface is moist. There are abundant nerves under the mucosa of labia minora, so it feels sharp. Unmarried and married puerperal women, labia minora is closed, which plays a role in protecting vagina and internal genitalia, and is a part of women's natural defense function.

Clitoris: The protruding place in front of the labia minora on both sides is equivalent to a man's penis, which is rich in nerve endings, so it feels very sensitive and has abundant venous plexus, which makes it easy to bleed after injury.

Vaginal opening and hymen: Vaginal opening is covered by an incompletely closed mucosa, which is called hymen. There is a hole in the middle of the hymen, through which women's menstrual blood flows every month. The size, shape and thickness of hymen hole vary from person to person. Some hymens are very thin, and strenuous exercise or gymnastics will cause the rupture of the female hymen. On the contrary, some people have a thick hymen and a loose hymen hole. Even if there is a history of sexual intercourse, it may not cause rupture, and some will rupture after delivery.

There are also women whose hymen is imperforate, which is called "imperforate hymen". This is a congenital malformation. The patient has no menstruation after sexual maturity and has periodic abdominal pain. This disease only goes to the hospital, so please ask the doctor to cut the hymen.

Vestibular gland: a gland located on both sides of the lower end of vagina, opening between labia minora and hymen. The fluid secreted during sexual intercourse lubricates the vaginal opening. Because of the narrow glandular duct, it is easy to hide bacteria and cause infection, forming a large vestibular gland cyst or a large vestibular abscess.
