Diaphragms/cervical caps

What is it? A dome of rubber which is put over the cervix before sex to stop sperm entering the uterus and meeting an egg. It should be used with a spermicidal cream, jelly or pessaries that contain a chemical that kills sperm.

    Advantages:
  • There are no side effects 
  • May be put in any time before sex 
  • Not affected by any other medicines 
  • There are no hormones involved so will not effect levels of fertility 
  • May offer some protection against cancer of the cervix
    Considerations:
  • May reduce the spontaneity of sex
  • Spermicides may cause irritation or an allergic reaction 
  • May take time to learn how to use 
  • Must stay in place for six hours after sex 
  • Will need to be replaced if weight is gained or lost or after giving birth, miscarriage or abortion 
  • Does not protect against sexually transmitted infections

Available from: A medical professional will need to fit a diaphragm initially to check what size is needed. Available from your GP, local family planning clinic or specialist clinic such as Marie Stopes Reproductive Choices

Effectiveness: When used correctly it is 92% - 96% effective
