The cervix is actually the cervical part of the uterus, which is also a cylindrical fleshy tissue that can be observed with the naked eye in the vagina, and is usually touched by the penis during sexual intercourse. Although the cervix cannot produce menstruation, it is a channel for menstrual blood to flow out, and it is also prone to various diseases, the most common of which are cervical erosion, cervical polyps, cervical intraepithelial neoplasia, and even cervical cancer. Therefore, in order to detect cervical cancer as early as possible, it is recommended to have regular cervical tct and hpv tests every year to exclude cervical intraepithelial neoplasia and cervical cancer. For women who have contact bleeding after intercourse, it is more likely to consider localized cervical problems, most often caused by cervical erosion or cervical polyps. Although women’s cervix does not have an endocrine or other substantial role, it is susceptible to various diseases and therefore requires regular routine medical checkups.
