Like the diaphragm, the cervical cap works like a plug. Made of soft latex or silicone with a round rim, it is pushed up into the vagina until it covers the cervix so no sperm can enter the uterus. The cap is smaller than the diaphragm and only covers the cervix. It requires an initial fitting by your healthcare provider. The cervical cap should not be used alone; to keep yourself properly protected the cap should always be paired with a spermicide.
With clean hands, start by filling the cap’s dome with spermicide. You will need to coat the cap’s edges and flipside as well. Now, squeeze the cap together, insert it into your vagina and push up until it’s sitting comfortably over your cervix. Make sure you can feel the handle as you will need it to remove the cap. You must leave the cap in place for at least 6 hours after having sex and you may leave the cap in for up to 48 hours. To remove the cap, squat down and press the dome to break the suction. Locate the handle and use it to gently pull it out.
