Diaphragm

What is a diaphragm?

A diaphragm is a latex cup prescribed for you by a physician that is inserted into the vagina to prevent pregnancy. It is most effective when used with spermicide.

How does a diaphragm work?

The diaphragm is inserted into the vagina and covers the cervix, blocking the opening to the uterus. This keeps the sperm from joining with an egg. When used with spermicide, the diaphragm blocks the joining of the sperm with an egg and also stops the sperm from moving.

How effective is this method?

The diaphragm is 84-94 percent effective in preventing pregnancy.
