Birth Control | DiaphragmDiaphragm

Traditionally, there were many different sizes of diaphragms and patients needed to be fitted by a healthcare provider. Now there is a universal diaphragm available that is “one size fits most”, known as the Caya diaphragm.

To use a diaphragm, before having sex, add spermicide (to block or kill sperm) to the device. Place it inside your vagina to cover your cervix. It must be left in place for at least  6-8 hours after sex to be the most effective at preventing pregnancy. The diaphragm should be taken out within 24 hours.
