Diaphragms are inserted into the vagina before sex, and cover the cervix so that sperm can’t get into the womb (uterus).

PLEASE NOTE Diaphragms and Caps are not as effective as other barrier methods – there is still a significant pregnancy risk with their use.
Diaphragms and caps wont alter your periods and contain no hormones.
They’re 92-96% effective at preventing pregnancy with perfect use and around 71-88% effective with typical use. This means that around 12-29 users will get pregnant in one year.
You also have to remember to put it in before you have sex and ensure it is fitted correctly to avoid pregnancy.
To be effective, diaphragms and caps should be used with a spermicide. Spermicide is a substance that kills sperm. It’s available in different forms, such as cream or gel. When using this form of contraception you only need to think about it before you have sex and can put a diaphragm/cap in several hours before you have sex – add extra spermicide if sex takes place more than three hours after putting it in.
You can get this method of contraception from your local Spectrum Sexual Health clinic. Find your nearest clinic here.
