It is now marketed again in France and can be obtained in pharmacies and from the French Family Planning Association. It is prescribed by a doctor or a midwife in a consultation. This method of contraception during sexual intercourse must always be used with a spermicide placed on each side of the diaphragm. It is placed deep in the vagina in order to cover the cervix within 2 hours before sexual intercourse.
It must be left in place for 6 hours after sexual intercourse. If the couple has sexual intercourse again, the spermicides must be applied again. It is made of latex or silicone and can be used after careful washing and drying. It has a life of approximately 2 years.
it does not protect against sexually transmitted infections or HIV infection.
