What is it?
It is a barrier method that a woman fits inside her vagina.
How does it work?
The diaphragm covers the woman’s cervix (neck of womb), and this stops a man’s sperm from reaching her egg.
You can use spermicide to cover the diaphragm. This will help it work better.
- You can put the diaphragm in place any time before you have sex (extra spermicide may be needed).
- You can re-use the diaphragm after careful washing with water.
- It is useful for women who wish to avoid hormones.
- You need to have a check-up at least once a year to make sure it still fits.
- You have to use spermicide every time you have sex.
- You must leave the diaphragm in place for at least six hours after sex, but must not leave it in for more than 24 hours.
- Some users suffer from cystitis (a swollen bladder which means you find it painful to pee).
- It does not protect against sexually transmitted infections.
