The uterus is an organ that produces menstruation and gives birth to the fetus. It is located in the center of the pelvic cavity, between the bladder and rectum. The size of the uterus is related to age and fertility. The virgin is about 7.5 cm long, 5 cm wide and 3 cm thick.
The uterus can be divided into three parts: the base, the body and the neck. The uterine cavity is an inverted triangle with a depth of about 6 cm. The upper two horns are the "uterine horns" leading to the fallopian tubes. The lower end is as narrow as an isthmus and about 65438±0cm long. The isthmus gradually expands during pregnancy and forms the lower uterine segment during delivery.
The ratio of uterine body to cervix changes with age, which is 1: 2 in infancy, 1: 1 in adolescence and 2: 1 in growth period. The uterus is normal and slightly bent forward. The anterior wall is located on the bladder, almost at right angles to the vagina. The filling degree of bladder and rectum can change the position of bladder and rectum. The uterine wall consists of serosa, muscularis and mucosa from outside to inside.

Acts endangering the uterus:
1, sexual life is unclean and disorderly.
Sexual life is too private and unclean, which will lead to cervicitis, salpingitis and vaginitis, and also induce vaginal cancer and cervical cancer. In addition, sexual life during the confinement and menstrual period will increase the risk of cervical cancer, so it is necessary to lead an honest and clean life before and after sexual life, and wash the reproductive parts with flowing water.
2. Multiple abortions and multiple births.
When unexpected pregnancy occurs, some people will terminate the pregnancy through induced abortion, and repeated induced abortion in a short time will bring serious harm to the uterus. Especially when doing abortion in a small clinic, doctors can't accurately see the uterine cavity. The size and position of the uterus were not clearly checked before the operation.
If the instrument is forced too hard or the direction of entry is different from the curvature of uterus, it will cause uterine perforation or adhesion between uterine cavity and cervix. In addition, multiple pregnancies and multiple births increase the risk of uterine diseases.
