What does the cervix do?

Cervical erosion mainly occurs in the cervix of the uterus. The cervix protrudes into the vagina and contains glands that secrete a kind of mucus, namely cervical mucus. The properties and amount of this mucus, like the endometrium, are affected by ovarian function and show obvious cyclical changes.

So, what role does the cervix play in the human body?

1) The cervix can secrete mucus, and as the menstrual cycle changes, under the action of estrogen, the cervical mucus becomes very thin, making it easier for sperm to pass through. This is also the first hurdle for sperm to pass through.

2) The inner wall of the cervical canal has many recesses and fissures, which can temporarily store sperm for 1 to 2 weeks. After the sperm gains energy, it can enter the uterus.

3) After pregnancy, a woman's uterus will continue to grow to accommodate the growth of the fetus, but the cervix will remain closed to ensure the safe growth of the fetus in the uterus until the pregnancy reaches full term.

4) During a woman's delivery period, the cervix will gradually soften and begin to expand, and the cervix will open wider, opening the first door for the smooth delivery of the fetus. It can be said that the cervix is ​​the only way for the fetus to be delivered.

In addition, some people believe that the cervix is ​​also a sexually sensitive organ and has a certain relationship with sexual life.
