A cervical cap is a thin latex or silicone membrane. It is available in several sizes - your doctor or midwife will tell you which size is suitable for you and will prescribe it for you in France in a consultation. Positioning it requires learning by the woman who is using it. It is positioned before sexual intercourse (no more than 2 hours before) in order to cover the cervix and is used with spermicides. The cap must remain in place for 6 to 8 hours after sexual intercourse in order for the spermicides to have time to act. It is made of latex or silicone and can be reused after being carefully washed and dried. It is available in pharmacies but is not reimbursed by the French National Health Insurance system.
