The cervix usually refers to the neck of the uterus, and this is one of the more important organs of tissue in the female reproductive system. The cervix is located mainly in the lower part of the uterus and is roughly about 2.5 to 3 centimeters long, with the upper end being mainly connected to the uterine body, while the lower end goes deep into the vagina. Like the endometrium, the cervix is affected by ovarian function and shows cyclic changes, with thinning of the cervical mucus during ovulation, which facilitates sperm penetration. After ovulation, under the action of progesterone, the cervical mucus decreases and becomes sticky. The cervix is an important line of defense against pathogens entering the internal genitalia, and is itself subject to a variety of disease-causing factors, so it is often involved in gynecology, obstetrics, family planning, reproductive health, women’s health care, and disease prevention and treatment. Common cervical diseases include inflammation, cervical pregnancy, benign tumors, malignant tumors, and local injuries. Women should pay attention to personal and sexual hygiene, pay attention to routine medical checkups, and when women have difficulties with cervical diseases, they need to cooperate with the doctor as soon as possible, so as not to delay the condition.
