The Diaphragm or Dutch Cap is a barrier method of contraception. It stops the man's sperm reaching the woman's ovum. Diaphragms are dome-shaped discs made of rubber.
They are inserted into the woman's vagina so they cover the cervix. This blocks the path of the sperm. Diaphragms must be inserted before intercourse takes place. They should also be covered with a spermicide - a cream which kills sperm.
