Our bottom line

The diaphragm is easy to use, but needs to be inserted into the vagina correctly. It's most effective (and recommended) when used with a spermicide, which can be irritating and messy.

  • Usually inexpensive, and can be used for up to 2 years.

More birth control methods


  • Requires a prescription, and sometimes a fitting (depending on which diaphragm you get) that can cost up to $200 without insurance.
  • Not recommended for use during your period – best to use another method of birth control around this time.
  • Might take some practice to insert and remove it correctly.
  • Must be left inside the vagina for 6 hours after sex in order for it to work.
  • You have to be comfortable with your body since you insert and take it out on your own.
  • Best when used with a spermicide, which can irritate some women's vaginas or cause urinary tract infections.
  • Doesn't protect against STDs.
How it works

The diaphragm works by covering a woman's cervix and keeping sperm from getting to the egg. When used with a spermicide, the spermicide kills sperm, reducing the chances of becoming pregnant.
