Diaphragm for Birth Control

Table of Contents


Overview

The diaphragm is used to prevent pregnancy. It is called a barrier method because it keeps the sperm and eggs apart. It is usually made of silicone and shaped like a dome, and it has a firm, flexible rim. It fits inside your vagina and covers the cervix, which is the opening of the uterus.

You use the diaphragm each time you have vaginal sex. You must use spermicide with it.

Before vaginal sex, apply spermicide to the diaphragm and place it in your vagina. If you have sex more than 1 to 2 hours after placement, apply more spermicide to your vagina. If you have sex more than one time when the diaphragm is in place, apply more spermicide each time. Leave the diaphragm in place for at least 6 hours after sex. Do not leave it in for more than 24 hours.

You need a prescription from your doctor for a diaphragm. Depending on the type of diaphragm, you may need to be fitted for the right size by your doctor. A diaphragm will last for 1 to 2 years.

How well does it work?

In the first year of use:

There is less chance of getting pregnant if you and your partner use an external (male) condom with the diaphragm.

Be sure to tell your doctor about any health problems you have or medicines you take. Your doctor can help you choose the birth control method that is right for you.

What are the advantages of using a diaphragm for birth control?

What are the disadvantages of using a diaphragm for birth control?

If you think you used the diaphragm incorrectly, you can use emergency contraception to help prevent pregnancy. The most effective emergency contraception is an IUD (inserted by a doctor). You can also get emergency contraceptive pills. You can get them with a prescription from your doctor or without a prescription at most drugstores.
