Caps & Diaphragm – NHS Sexual Health & Blood Borne Viruses | Tayside

How does it work?

Caps and diaphragms are barrier methods of contraception that fit inside your vagina and cover your cervix (entrance to the uterus – womb) stopping sperm reaching an egg.  It is recommended that caps and diaphragms are used with spermicide which kills the sperm.

What are the advantages?

  • Caps and diaphragms are 92-96% effective if used according to instructions.
  • You only have to use it when you have sex
  • There are no serious health risks

Are there any disadvantages?

  • Some people find spermicide messy to use
  • Some people can be sensitive to the latex or chemicals in spermicide
  • It can take time to learn how to use it to ensure effectiveness

Where can I get it?

You can get caps and diaphragms from your GP or local sexual health clinic
