More About the Diaphragm
The diaphragm is a dome-shaped, shallow cup that’s made of soft silicone. You put it into the vagina to cover the cervix. You use it with a spermicide.
- Once it is in place, it works right away.
- You can have sex more than once while it’s in place. Just add more spermicide each time to increase the efficacy of the diaphragm.
- It is hormone-free, so it doesn’t affect your period.
- You and your partner shouldn’t be able to feel it.
- Diaphragms come in different sizes. One brand fits most people and you need a prescription to get one. Your clinician will give you an exam and tell you which type and size is best for you.
How to Use the Diaphragm
- You need to be okay touching yourself as you will need to put it into your vagina. Practice putting it in and taking it out before using it.
- Put a teaspoon of spermicide into the cup of the diaphragm and spread a little around the rim. Place the cup against the cervix (the opening of the uterus).
- You can put the diaphragm in up to two hours before sex.
- You must leave the diaphragm in for six hours after sex.
- After taking it out, wash it with soap and water and allow it to dry.
- Check for small holes or tears before and after you use it.

Effectiveness
The diaphragm is 83% effective with typical use. That is, on average, 17 out of 100 people using this method will get pregnant in a year. You can improve its effectiveness by:
- Using it with another method, such as withdrawal or a condom. This also reduces your chances of getting HIV and other sexually transmitted infections (STIs).
The diaphragm is 88% effective with perfect use. That is, if the diaphragm is used correctly all the time, 12 out of 100 people will get pregnant in a year.
- Perfect use means using a spermicide – and adding more every time you have sex.
