A cervical cap is a soft, thimble-shaped device that is inserted into the vagina and fits snugly over the cervix. Like the diaphragm, the cervical cap prevents sperm from reaching an egg. Yet unlike the diaphragm, the cap is much smaller. The cervical cap keeps sperm from entering the uterus by forming a secure seal around the cervix as suction keeps the cap in place. For added protection, the cap should be used with spermicide (like Gynol). The cap can be inserted up to 24 hours before having sex, but you must wait at least 6 to 8 hours after having sex to remove it.
FemCap is silicone cup that is offered in 3 sizes:
- Small (never been pregnant)
- Medium (had a c-section or abortion)
