Vaginal diaphragms are circular domes made of silicone with a flexible rim.
Cervical caps are smaller and are made of silicone.
REMEMBER: Condoms are the only contraception method to reduce the risk of sexually transmitted infections (STIs). Condoms can protect you from STIs such as syphilis and gonorrhoea, both of which have increased in the last couple of years.
