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.
