The uterus is a unique female organ, a vital reproductive organ, the place where new life is conceived, and of extreme importance to women. The uterus is located in the center of the pelvic cavity, between the bladder and the rectum, with an inverted triangular shape. Its position can vary with the degree of filling of the bladder and rectum or with body position. The uterus of a normal adult infertile woman is in an anteriorly inclined and forward-flexed position, and the uterus is fixed mainly by the pelvic diaphragm and the vaginal support and traction of the ligaments. The four pairs of ligaments are the broad ligament of the uterus, the round ligament of the uterus, the main ligament of the uterus, and the sacral ligament of the uterus. The primary functional roles of the uterus are to produce menstruation and to nurture the fetus. Menstruation is a cycle of autonomous thickening of the endometrium, vascularization, glandular growth and secretion, and endometrial collapse and shedding accompanied by bleeding. The onset of menstruation represents a woman’s ability to conceive. The fertility function is an important function to complete human reproduction and continuation, and is a sign of a woman’s maturity. In addition, the uterus plays an irreplaceable role by participating in the endocrine function as well as the immune function of a woman. The uterus is very important for women, so it is important to protect it in normal life, to have regular gynecological examinations, and to do a good job of contraception, knowing that a single abortion can do a lot of damage to the uterus. Therefore, in recognizing the role of the uterus, but also to do to protect the uterus, the benefit is always the women themselves.
