The vagina is a part of the female reproductive system, which also includes the ovaries, uterus, and vulva, or external genitalia. The vagina is an elastic tube that connects the uterus and vulva. The vagina is used mainly during sexual intercourse, menstruation and childbirth. Depending on the specific function the vagina has different size. The biggest enlargement occurs during childbirth when a head of the newborn has to pass through the vagina. The most common disease is vaginal inflammation, tumors are rather rare.


The vagina is an important organ of the female reproductive tract. It is an elastic tube. The vagina mediates the connection between the uterus and the vulva or the external environment. In the mucous of the vagina, there are many microorganisms, and one of them is lactobacillus. Lactobacillus keeps a naturally low pH in the vagina, and together with the local immune system it prevents the development of inflammation.

Vagina structure

The vagina is a tube whose wall is composed of smooth muscle. Average length of the vagina is 7-8 cm and the width is about 3-5 cm. These are highly variable data whose values differ not only individually, but also in a woman with regard to the specific function of the vagina, the values may change. Normally the vagina is closed and the walls are pressed on each other. During sexual intercourse it is not only able to expand, but also slightly prolong. The largest expansion occurs naturally during childbirth, when the newborn must pass through the vagina and especially its largest diameter, the head. The entrance to the vagina is located in the vaginal vestibule, which is part of the vulva, or external genitalia, under the external urethral orifice. It is covered with labia minora. Before the first sexual intercourse, there is also an extra hymen. The end of the vagina is surrounded by the neck of the uterus and the transition between the vagina and the uterus is separated by the cervix. In front of the front wall of the vagina is located the bladder. Through its rear wall it is adjacent to the anus. This arrangement allows the examination of the vagina through the rectum which can bring a number of important information.

Vagina function

Regarding the function of the vagina, vital is the fact that it mediates the connection between the uterus and the vulva, thus the external environment. During menstruation it removes the menstrual blood from the uterus. A tampon is inserted into the vagina during menstruation to absorb blood. During sexual intercourse the penis is inserted into the vagina. For a smoother insertion lubricating substances are formed in the Bartholin gland, which is located near the entrance of the vagina. During sexual arousal these substances are released. The surrounding of the vaginal entrance is richly innerved, its stimulation leads to sexual excitement, and due to its high sensitivity, it can lead even to orgasm. After ejaculation the vagina serves as a reservoir for sperm that accumulate near the cervix. The vagina allows the passage of sperm into the uterus and then into the fallopian tubes, where a mature egg is fertilized. The vagina is also a part of the birth canal. During natural childbirth the newborn gets through it into the world. Due to the relatively large width of the newborn's head the vagina has to open greatly and it is a great burden for it.

Vaginal diseases

Probably every woman during her life underwent at least one inflammation of the vagina, called colpitis or vaginitis. This inflammation is one of the most common reasons for visiting a gynecologist. Furthermore, in this area cancer can also occur. Fortunately, that is relatively rare. During childbirth a so- called birthing injury can occur. One of its consequences is incontinence after many years, or involuntary loss of urine.

Vaginal inflammation

Vaginal inflammation is an overgrowth of certain bacteria in the vagina. Under normal circumstances, their reproduction is in balance thanks to lactobacillus and acidic pH. However, if this balance is disrupted, for example by, hormonal influences, antibiotics, sexual activity or overall disease and weakening of the immune system, this leads to bacteria overgrowth and consequently vaginal inflammation occurs. It is characterized by burning and itching of the genitals, usually whitish smelly discharge, burning or cutting sensation during urination, and pain during sexual intercourse. The treatment of vaginal inflammation involves mainly the administration of antifungal agents in the form of oral tablets or vaginal suppositories, and in many cases it is also necessary to treat the sexual partner.

Vaginal cancer

Cancer of the vagina is extremely rare and mainly affects women over 50. In the vast majority these tumors are spread to the vagina from the urethral opening or external genitalia. Symptoms of vagina cancer include vaginal soreness or pain in the lower abdomen, watery discharge, irregular menstrual bleeding, and difficulty with urination or constipation. Treatment is mainly surgical removal of the tumor from the vagina or more radical removal of not only the entire vagina, but the uterus, fallopian tubes and ovaries. In many cases it is possible to detect vaginal cancer early and treatment is successful, as well as other diseases affecting the female sex, and therefore it is necessary to regularly visit a gynecologist.

Zizou: I am so glad to hear that you want to wait until marriage. You will be happy if you do dedcie to wait until marriage. Speaking from experience: I don't believe you need to worry about a lot of blood coming out. While everyone is different, it's usually just a little spotting. If he's your husband & he knows it's your first time, just ask him to be gentle & take his time until you're comfortable. If your husband is gentle & takes his time there will not be a ruined moment because of blood. I think the stories you've heard were a little exaggerated. Yes, in the old testament they used to bring the sheets out, but I've never heard that it was saturated with blood. I believe it was just a little spotting:)
