How big is a woman's uterus?

The uterus is very important for women. It is not only a female reproductive organ, but also a place where new life is nurtured. Usually after a woman becomes pregnant, her belly will become bigger and bigger, making the uterus particularly large. Therefore, many people are curious about the size of the uterus. In fact, the size of the uterus varies from person to person. It is not the same. Everyone's physical condition is different, and the size of the uterus also varies.

How big is a woman's uterus?

To talk about how big the uterus is, the uterus of a mature woman who has not given birth is about 7.5 cm long, 5 cm wide and 3 cm thick. The uterus can be divided into three parts: the uterine fundus, uterine body and cervix. It is an inverted triangle with a depth of about 6 cm. It has a uterine horn on the top that leads directly to the fallopian tube. The lower part is relatively narrow, called the isthmus, which is about 1 cm long. As a woman becomes pregnant, this isthmus will gradually expand, and when delivery is approaching in the late pregnancy, this isthmus will become the lower part of the uterus.

The ratio of the uterine body to the cervix changes with age, being 1:2 in infancy, 1:1 during puberty, and 2:1 when reaching the reproductive period. The normal shape of the uterus is slightly curved, with the front wall lying prone and almost at a right angle to the vagina. Its position can also change with the position of the rectum or bladder.

If a woman's daily menstrual cycle is normal, the size of her uterus will basically be stable. The uterus of non-pregnant adult women is tilted forward and fixed between the pelvic diaphragm and the vagina. The position of the uterus will be slightly affected after childbirth. If a woman has abnormal menstruation, it may affect the shape of the uterus. Six hormone tests can be performed to confirm whether organic changes have occurred. As a woman, you should pay attention to personal body care. Uterine health is related to many aspects of female body changes. Even skin health is related to uterine health. If the uterine function declines, the skin quality will deteriorate accordingly. Therefore, caring about uterine health means protecting your skin and body health.
