Diaphragms

Key Points for Providers and Clients
  • The diaphragm is placed deep in the vagina before sex. It covers the cervix. Spermicide provides additional contraceptive protection.
  • A pelvic examination is needed before starting use. The provider must select a diaphragm that fits properly.
  • Require correct use with every act of sex for greatest effectiveness.

What Is the Diaphragm?

  • A soft latex cup that covers the cervix. Plastic and silicone diaphragms may also be available.
  • The rim contains a firm, flexible spring that keeps the diaphragm in place.
  • Used with spermicidal cream, jelly, or foam to improve effectiveness.
  • Most diaphragms come in different sizes and require fitting by a specifically trained provider. A one-size-fits-all diaphragm is becoming available. It does not require seeing a provider for fitting (see Question 9).
  • Works by blocking sperm from entering the cervix; spermicide kills or disables sperm. Both keep sperm from meeting an egg.
