A diaphragm birth control is a circular dome made of thin, soft silicone thats inserted into the vagina before sex. It covers the cervix so sperm cannot get into the womb to fertilize an egg. When used correctly with spermicide, a diaphragm is 92-96% effective at preventing pregnancy. Here are some key points about diaphragm birth control:

• A diaphragm is a form of birth control that’s a shallow cup shaped like a little saucer thats made of soft silicone.
• It works as a barrier that covers your cervix, stopping sperm from joining an egg.
• A diaphragm is a reusable dome-shaped cup that fits over the opening of the cervix.
• It is common to use a diaphragm with spermicide, which is a gel, cream, or foam that kills sperm.
• There are four types of diaphragms made of either latex or silicone.
• You must use your diaphragm correctly each time you have sex. With spermicide, this method can prevent pregnancy.
• You should never use a diaphragm during your menstrual period. You will need to use another form of birth control at this time.
• You can put your diaphragm in up to 2 hours before you have sex. If the action starts more than 2 hours after you insert your diaphragm, reapply the spermicide before you have sex.
• You should not leave a diaphragm in your vagina for more than 24 hours. This can cause irritation, infection, or a medical condition called toxic shock syndrome.
• A diaphragm may be a good option for a young woman who can take responsibility for protection before having sex. With a diaphragm, she must always have a supply of spermicide.
