What are they?
The diaphragm is a soft silicone cup with a flexible ring that’s worn inside the vagina covering the cervix (the opening of the uterus). The cervical cap is similar to the diaphragm, but smaller. It is also worn over the cervix. Both barrier methods block the sperm from getting to the egg. They are always used with a spermicide and both come in different sizes. A clinician will fit you for the correct size.
