- Diaphragms and caps are types of contraception you put inside your vagina before sex. You need to use them with spermicide (gel, foam or cream that kills sperm).
- Diaphragms and caps are discs or small domes made of thin, soft silicone or latex. They cover the cervix (entrance to the womb).
- They prevent pregnancy by stopping sperm entering the womb.
- Diaphragms and caps are not suitable for everyone.
- Caps are smaller than diaphragms and you can leave them in for longer.
- If correctly used diaphragms and caps are estimated to be between 92 and 96% effective. If not used correctly they are less effective.
- You can compare different methods, including how well they work and side effects, when choosing a method of contraception.
Information:
Diaphragms and caps do not stop you getting or passing on sexually transmitted infections (STIs). Use a condom every time you have sex to protect you and your partner against STIs including HIV.
