Diaphragm
82 - 86% effective
24 hour use
A diaphragm is a shallow, cup-shape device made of silicone. You self-insert the diaphragm into your vagina using a special spermicidal gel, to cover your cervix.
The diaphragm and gel make a barrier to prevent sperm from passing through the cervix into the uterus.
It can be inserted up to 2 hours before sex and it must stay in place for at least 6 hours after sex. It can stay in place for a maximum of 24 hours.
Diaphragms can be purchased without a prescription from some pharmacies, family planning clinics or online.
Most people and their partners can’t feel the diaphragm during sex.
After you remove the diaphragm, it can be washed with soap and warm water. It should be stored in a clean place away from heat or direct sunlight.
