Cervical mucous - Definition

Ask a question


Cervical mucous is a viscous substance produced by glands located in the cervix. It serves as a protective barrier between the uterus and the outside environment by "trapping" pathogens such as bacteria or viruses, as well as preventing the progression of sperm when it is not the optimal time for conception. The cervical mucous consistency naturally fluctuates around the time of ovulation, becoming less viscous to facilitate the sperm's progress up the woman's genital tract and optimize their chance of meeting the ovule.
