What Is the "Little Tongue" Inside the Vagina?

The small tongue inside the vagina is generally the cervix. The cervix is a very important reproductive part of women, connecting the upper end of the uterus and extending deeply into the vagina without special symptoms. If similar small tongue-like tissues are found in other reproductive parts besides the vagina, it may be condyloma acuminatum, a sexually transmitted disease that is relatively easy to identify.

The cervix is located in the lower part of the uterus, resembling a cone, with a length of 2.5 to 3 cm. The upper end is connected to the uterine body, and the lower end extends deeply into the vagina. The vault at the top of the vagina divides the cervix into two parts: the cervical vaginal part protruding into the vagina, and the upper cervical vaginal part above the vaginal vault. The central part of the cervix is a slightly flattened long shuttle-shaped cavity, with its upper end connected to the uterine cavity through the internal cervical os and its lower end opening into the vagina through the external cervical os. The cervical canal is located between the internal and external os. The external cervical os of women who have not given birth is round, while those who have given birth through vaginal delivery are horizontally fissured.

First, viscous uterine cavity mucus can greatly hinder the movement of sperm. Generally, mild cervical erosion has little impact on fertility for women, but moderate to severe cervical erosion can affect conception by causing viscous secretions that prevent sperm from entering the cervix. Second, the secretions caused by cervical erosion contain a large number of white blood cells and pathogenic viruses, which can not only damage the vagina but also significantly affect female sperm vitality. Third, cervical mucosa inflammation can stimulate the formation of cervical polyps, which can block the cervical os and prevent male sperm from passing normally.
