The cervix secretes mucus, which serves several functions: (1) lubricates the vaginal canal, (2) forms a barrier to sperm penetration into the uterus during nonfertile periods, (3) provides an easy-flowing pathway to facilitate sperm passage into the uterus during fertile periods, (4) provides an alkaline environment to facilitate the viability of sperm that have been deposited in the acidic vagina, (5) forms a solid plug called an operculum to protect a pregnancy from outside pathogens, and (6) functions as a bacteriostatic agent.
