Online Birth Control Education
The diaphragm is a dome shaped latex or silicone cup that fits securely in the vagina and covers the cervix. It should always be used together with a spermicidal gel formulated for diaphragm use. It works by blocking the opening to the uterus and holds spermicide that may slow destroy sperm cell membrane. The diaphragm can be inserted into the vagina at the time of intercourse or up to six hours before intercourse. After intercourse, the diaphragm is left in place for at least 6 hours. Using it longer than 24 hours is not recommended because of the very rare but possible risk of toxic shock syndrome.
The diaphragm is fitted by a healthcare provider. It comes in a variety of sizes from 2-4 inches in diameter. Instructions on insertion and removal techniques are reviewed at the visit. With proper care, diaphragms can last up to two years. They must be refit after pregnancy.
