Diagram of the normal female uterus

The uterus is an important part of the female reproductive organs. There are many factors that affect the size of the uterus. The uterus is also a key factor in determining the female reproductive health and pregnancy. Therefore, women must take good care of their uterus. Regarding the normal uterine size and the factors that affect the size of the uterus, let’s discuss the detailed explanation given by the editor below!

Normal uterine size

The uterus, as the place where life is created, has a complex structure and is located above the female vagina. The structure of the uterus is divided into the serosa, muscularis, and mucosa from the outside to the inside. The endometrium is divided into three layers from the outside to the inside: the exometrium, the myometrium, and the uterine wall.

What is the normal uterus size range? The size of the uterus is 5.5-7.5cm in longitudinal diameter, 3.0-4.0cm in anteroposterior diameter, 4.5-5.5cm in thick diameter, and 2.5-3.0cm in cervical length. The range of a normal uterus in an adult woman is 6~7*5~6*3~4CM, and the endometrial thickness of 8mm is also within the normal range.

Your uterus will grow as you age. The uterus of a woman who has given birth to a child will be much larger, while the uterus of a woman who has not given birth to a child will be smaller. If the uterus is small, it will generally not affect fertility if there are no side effects.

Factors that affect uterine size

1. Age

The size of the uterus is directly related to the actual age of women. If a woman is still pregnant, it is normal to have a small uterus. Because she is still in the growth and development stage, there is no need to worry too much.

2. Endometriosis

The size of a woman's uterus may also be caused by endometriosis. Generally speaking, women with endometriosis will have a uterus that is twice as large.

3. Developmental malformation

There is also a situation where a woman is born with a deformed uterus. There are also situations where a woman is born with an enlarged or small uterus. Generally speaking, if it is a congenital problem with the size of the uterus, there is no way to treat it.

4. Miscarriage

If a woman suffers repeated miscarriages, it will also affect the normal size of the uterus. Because abortion requires uterine curettage, it is easy to change the size of the uterus. In serious cases, it may lead to infertility.
