The vagina is a muscular organ that has a thin, yet elastic wall. If necessary, it has the ability to expand and stretch, like a balloon. The structure of this organ is simply amazing, because the size of the vagina depends on how all the necessary processes will take place, such as fertilization or childbirth, as well as the discharge of excretory functions.
Research scientists and attempts to measure the external and internal genital organs of women began in 1995 and continue to this day. The size of the vagina depends on several factors. So, for example, in an unexcited state, the size can be from 7 to 9 cm, and in an excited state from 13 to 19.
What size a woman has a vagina may also depend on childbirth, especially the fast-paced. If the baby was born large, then its size changes. The vagina after birth becomes elastic. As a result, sensitivity during intercourse will be significantly reduced. Based on the research, it can be concluded that up to 60 years of age, the change in size is not significant: in a relaxed state - up to 1-2 cm, while in an excited state - practically unchanged.
Studies have shown that the size of a woman's vagina also depends on the presence of sexual relations. The difference between married and single women is practically insignificant, can reach a length of 2-3 cm. As you can see, this organ is a kind of elastic channel. It is like a tensile muscle tube that connects the vulvar region and the uterus. In different women, the size of the vagina is at least slightly, but different. It changes due to folds. They are formed by a lined stratified squamous epithelium on the vaginal mucosa. If a woman is just standing, then this body can slightly change its shape. The vagina bends slightly upwards. In this case, it does not occupy either a vertical or horizontal position. If we talk more about the walls of the vagina, then they consist of several layers and have a thickness of up to about 4 mm. This includes the internal multilayer epithelium, or, as it is also called, adventitious, consisting of loose tissue. And they also distinguish the front wall, as well as the posterior half of the vagina, which are interconnected.
In order for the fetus to be able to exit during childbirth, the vagina expands by more than 10 cm in diameter. The middle layer, smooth muscle, provides such a feature. And the outer one connects the vagina with neighboring organs that are not related to the internal genital organs, such as the bladder, and, of course, the rectum, located on both sides of the vagina. The uterine cavity and walls inside the vagina, as well as the entire channel of the cervix, are filled with special glands that secrete mucus. Such a liquid plays an important role in the work and life of the female organs. It moisturizes a healthy, normal vagina, and also cleans it of various bacteria and germs and other “biological debris”.
