How big is a normal uterus?

The uterus is a very important reproductive organ for women and is also very prone to disease. Many problems that women experience are directly related to the condition of the uterus. For example, many women cannot become pregnant normally because their uterus is too small. Therefore, it is very necessary to understand the size of the uterus. So, how big is a normal uterus? Let’s take a closer look at it below.

The uterus is the organ that produces menstruation and nurtures the fetus. It is located in the center of the pelvic cavity, between the bladder and the rectum. The size of the uterus is related to age and fertility. For nulliparous women, it is approximately 5cm long, 5cm wide and 3cm thick. The uterus can be divided into three parts: the fundus, the body and the neck. The uterine cavity is an inverted triangle, about 6 cm deep, with the two upper corners being the "uterine horns" that lead to the fallopian tubes. The narrow lower end is called the "isthmus", which is about 1 cm long. The isthmus gradually expands during pregnancy and forms the lower uterine segment at the time of delivery. The ratio of the uterine body to the cervix varies with age, being 1:2 in infancy, 1:1 in adolescence, and 2:1 during the reproductive period. The uterus is normally slightly curved forward, with the anterior wall lying prone on the bladder and almost at right angles to the vagina. Its position may change with the degree of fullness of the bladder and rectum. The uterine wall is composed of three layers from outside to inside: serosa, muscle layer and mucosa (i.e. endometrium).

The uterus of an adult woman is about 7-8 cm long, 4-5 cm wide at the bottom, 2-3 cm thick, and weighs about 40-50 grams. The lower end is connected to the vagina, and it will have complex reactions during intercourse, giving women a wonderful feeling.

The uterus is located in the middle of the pelvis, between the bladder and rectum. Its position may vary depending on the fullness of the bladder and rectum or body position. When standing upright, the uterine body is almost parallel to the horizontal plane, the uterine fundus lies above the posterior and superior part of the bladder, and the cervix remains above the plane of the ischial spines.

The uterus is an important part of the female internal reproductive organs. The fertilized egg passes through the fallopian tube and finally implants in the uterus. The tiny life begins to grow slowly in the female uterus. After ten months of development, a life leaves the uterus and comes into this world. The uterus, as the place where life is nurtured, has a complex structure and is located at the upper end of the female vagina. The structures of the uterus from outside to inside are the serosa, muscularis, and mucosa. The uterine wall is divided into three layers from outside to inside: the exometrium, myometrium and endometrium.

The above is an introduction to the size of a normal uterus. I hope it will help you understand. Like other organs, a woman's uterus also has a normal size. Although the size of the uterus may change over time, as long as it falls within the overall size range, there is no problem. However, if the excess area is relatively large, effective measures should be taken in time for treatment.
