A diaphragm is a dome shaped barrier that covers the cervix (the entrance to the uterus) to prevent sperm from entering the uterus. It is a reusable method that is made from silicone. The diaphragm is inserted before sex and needs to be used with compatible spermicide to be most effective. When used effectively, it is between 85-90% effective (10-15 pregnancies per 100 users in 1 year) against pregnancy. It does not reduce the risk of Sexually Transmitted Infections. Using condoms with the diaphragm will increase pregnancy protection and reduce STI risk.
The diaphragm can be inserted into the vagina several hours before sex and left in place for up to 24 hours.
In Victoria, you can access the Caya diaphragm through our friends at the Vancouver Island Women’s Clinic or 250-480-7338.
