Diaphragm and Cervical Cap

Slide 29

We will now discuss two other female barrier methods, the diaphragm and cervical cap. Both are made of soft latex rubber and are inserted into the vagina, fitting over the woman’s cervix. A diaphragm covers the entire upper part of the vagina including the cervix. It fits between the pubic bone and the posterior fornix of the vagina. Smaller than the diaphragm, a cap fits only over the cervix, where suction holds it in place. These devices do not make a perfect seal against the cervix, and it is possible for them to dislodge during intercourse. Thus, sperm may get past the physical barrier. For this reason, both devices are used with spermicidal cream or jelly.

When used with spermicides, the diaphragm and cervical cap prevent pregnancy by serving both as a physical and chemical barrier.

Neither the diaphragm nor the cervical cap is widely used in developing countries and often neither is available.
