Cervical mucus

Cervical mucus appears in response to estrogen. It is nothing to be “ashamed of,” and is a natural, healthy and clean fluid of the body just like tears or saliva. As a matter of fact, cervical mucus is necessary for the proper functioning of a woman’s reproductive system. Mucus also is an aid to fertility because it provides a swimming medium for sperm, provides nutrients for sperm, and enables sperm to survive for days in a woman’s cervix area where the sperm temporarily “take up residence” while waiting for ovulation.

When there is no mucus, sperm life is very short, measured in hours, because the normal vaginal environment is very acidic and hostile to sperm. Women can easily learn to become aware of their cervical mucus through what they feel and sense, and what they see.

Once observed, mucus is recorded on the fertility chart each day.
