Diaphragms And Caps
Diaphragms and caps are barrier methods that prevent sperm meeting an egg. They fit inside the vagina and cover the cervix (entrance to the womb). They’re made of latex (rubber) or polyurethane (plastic). They come in different shapes and sizes.
Vaginal diaphragms are circular domes with flexible rims. Caps are smaller than diaphragms. To be effective they need to be used with spermicide - a special cream or pessary that kills sperm.
Diaphragms and caps need to be used each time you have sex. Spermicide is applied to the diaphragm or cap, which is then inserted into the vagina to cover the cervix. They can be inserted any time before sex but if it’s more than three hours before sex you must use more spermicide.
The cap or diaphragm needs to be left in place for at least six hours after the last time you had sex. It can be left in longer if necessary.
Diaphragms and caps don’t suit everyone. They may not be suitable if you:
* Have vaginal muscles that cannot hold a diaphragm
* Have a cervix of an unusual shape or in an awkward position or you cannot reach it
* Have repeated urinary infections
* Have had toxic shock syndrome in the past
* Do not feel comfortable touching your genital area
