The size of the uterus does not vary from person to person. It is not true that if a person grows tall, the uterus is big, and if a person grows short, the uterus is small. The uterus has a certain normal range, for example, the uterus of an adult woman is about 7-8cm in length, 5-6cm in width and 4-5cm in thickness, which is a normal range. If it is larger than this range, it may be clinically due to certain diseases, such as inflammation of the uterine body, adenomyosis, fibroids and so on, which may lead to the enlargement of the uterus. If it is smaller than the normal range, it may be caused by uterine dysplasia. The uterus has a normal range in adult women, and if it develops abnormally, it is treated actively at puberty. If the uterus is enlarged due to pathology, it should be treated accordingly.
