Ovulation: How Does the Cervix Change at Ovulation?

My friend feels her cervix for changes. She says she can feel hers opening up just prior to ovulation. Can you explain this?


As a woman approaches ovulation, her estrogen increases, causing her cervix to become soft, high and open, and producing a very wet, fertile quality cervical fluid. A fertile cervix feels like your lips: soft and somewhat mushy. A handy mnemonic to help you remember this concept is the word SHOW, for Soft, High, Open and Wet. Right after ovulation, under the influence of progesterone, all the above signs reverse. That is, the cervix becomes firm, low and closed, and the cervical fluid dries up. An infertile cervix feels more like the end of your nose.

The changes in the cervix are what is referred to as a secondary fertility sign, as opposed to the two primary fertility signs -- waking temperature and cervical fluid. Primary fertility signs are those signs that all ovulating women experience all of the time, whereas secondary fertility signs are those which only some women experience, or only experience some of the time.

One of the subtle differences between the cervix of a women who has never had a vaginal birth versus those who have, is that a woman who has had children vaginally tends to have a cervix that has more of a slit-type cervical opening, as opposed to a tiny round circle.

The best way to feel the cervix is to insert your clean middle finger and feel it while squatting.
