DiaphragmIs The Diaphragm for Me?

Here are some of the most common questions we hear women ask about the diaphragm. We hope you find the answers helpful.

What Is the Diaphragm?

The diaphragm (DIE ah fram) is a shallow, dome-shaped cup with a flexible rim. It is made of silicone. You insert it into the vagina. When it is in place, it covers the cervix.

How Does the Diaphragm Work?

Diaphragms prevent pregnancy by keeping sperm from joining with an egg. In order to be as effective as possible, the diaphragm must be used with spermicide cream, gel, or jelly.

Diaphragms work in two ways:

  • The diaphragm blocks the opening to the uterus.
  • The spermicide stops sperm from moving.

How Effective Is the Diaphragm?

Effectiveness is an important and common concern when choosing a birth control method. Like all birth control methods, the diaphragm is more effective when you use it correctly.


  • If women always use the diaphragm as directed, 6 out of 100 will become pregnant each year.
  • If women don't always use the diaphragm as directed, 12 out of 100 will become pregnant each year.

You can make the diaphragm more effective if you

  • Make sure it covers your cervix before each time you have intercourse.
  • Make sure spermicide is used as recommended.

Your partner can help you make the diaphragm more effective by using a latex condom or pulling out before ejaculation.

Keep in mind that diaphragms do not protect you from sexually transmitted infections. Use a latex condom to reduce the risk of infection.

How Safe Is the Diaphragm?

Most women can use the diaphragm safely. But some conditions may make it difficult or impossible for some women to use a diaphragm.

The diaphragm may not be right for you if you

  • are not comfortable touching your vagina and vulva
  • are sensitive to silicone or spermicide 
  • gave birth in the last six weeks
  • have certain physical problems with your uterus or vagina
  • have difficulty inserting the diaphragm
  • have frequent urinary tract infections
  • have a history of toxic shock syndrome
  • have poor muscle tone in your vagina
  • recently had surgery on your cervix
  • recently had an abortion after the first trimester of pregnancy

Your health care provider can help you decide if the diaphragm is likely to be safe for you.

Only for You

Your diaphragm should be used by you and only you. Do not share it with friends. And don't ever use anyone else's diaphragm.

What Are the Benefits of the Diaphragm?

Using a diaphragm is safe, simple, and convenient. Women like the diaphragm because

 

  • It can be carried in your pocket or purse.
  • It can be used during breastfeeding.
  • It generally cannot be felt by you or your partner.
  • It has no effect on a woman's natural hormones.
  • It is immediately effective and reversible.
  • There is no interruption of sex play — it can be inserted hours ahead of time.

What Are the Disadvantages of the Diaphragm?

The diaphragm

  • may be difficult for some women to insert
  • may be pushed out of place by some penis sizes, heavy thrusting, and certain sexual positions
  • must be in place every time a woman has vaginal intercourse
  • may need to be refitted

Using Spermicide

Most spermicides that are used with the diaphragm contain nonoxynol-9. Nonoxynol-9 has certain risks. If it is used many times a day, or by people at risk for HIV, it may irritate tissue and increase the risk of HIV and other sexually transmitted infections.

Side Effects

Most women can use the diaphragm with no problems. Serious problems are very rare. But some women may experience some side effects.

  • Some women who use diaphragms may develop frequent urinary tract infections. To avoid infection, you can urinate before inserting the diaphragm and after intercourse. If you get frequent bladder infections, ask your health care provider to check to see if your diaphragm fits correctly.
  • Some women who use diaphragms may develop vaginal irritation. This can be a sign of a sensitivity to silicone or to spermicide. If you have a mild reaction, try switching brands of spermicide to clear up the problem. If that doesn't work, stop using the diaphragm until you speak with your health care provider.

Check with your health care provider if you

  • feel a burning sensation while urinating
  • are uncomfortable when the diaphragm is in place
  • have irregular spotting and bleeding
  • feel irritation or itching in the genital area
  • have redness or swelling of the vulva or vagina
  • have unusual discharge from the vagina

These symptoms may be a sign of infection or other condition. Most conditions are easily treated.

How Do I Use the Diaphragm?

With a little practice, the diaphragm is easy to use. Your health care provider will show you how to insert and remove your diaphragm and will then watch you insert and remove it. Practice inserting and removing it at home, too.

INSERTING A DIAPHRAGM

How long do I leave the diaphragm in? What if I have sex again?

The diaphragm must stay in place six hours after the last time you had vaginal intercourse.

If have intercourse again, or if you have intercourse more than six hours after you put the diaphragm in, leave the diaphragm in place and insert more spermicide deep into your vagina.

Do not leave the diaphragm in place for more than 24 hours.

A special inserter can be used to help with placement and removal. If you are having trouble inserting the diaphragm, talk to your health care provider about getting an inserter.

Make Sure It Fits

Diaphragms are available in many sizes and designs. A new size may be needed after any of the following:

  • a full-term pregnancy
  • abdominal or pelvic surgery
  • a miscarriage, or abortion after 14 weeks of pregnancy
  • a 20-percent change in weight

How Do I Take Care of My Diaphragm?

If you take good care of your diaphragm, it may last about two years. Taking care of the diaphragm is simple.

  • After you remove the diaphragm, wash it with mild soap and warm water.
  • Allow it to air dry.
  • Do not use any powders on the diaphragm — they can cause infections.
  • Do not use oil-based lubricants — such as Vaseline or cold cream — with your diaphragm. They can damage silicone.

Be sure to examine the diaphragm regularly. You can look for small holes or weak spots by holding it up to the light. If there is a hole or weak spot, light will shine through the diaphragm. You can also fill the cup of the diaphragm with water and look for leaks.

Diaphragms can still be used if the silicone becomes discolored. But if the silicone develops cracks or holes it has become too thin.

Stop using your diaphragm if you find that it has holes, weak spots, cracks, or wrinkles. Talk to your health care provider about getting a replacement. In the meanwhile, use another form of birth control, such as a condomfemale condom, or sponge.

How Do I Get a Diaphragm? How Much Does a Diaphragm Cost?

You must see a health care provider to get a diaphragm. Visit a Planned Parenthood health center, a clinic, or a private health care provider for a diaphragm.

When you go to get your diaphragm, your provider will examine you to make sure you do not have a condition that would rule out using a diaphragm. Then your provider will find the correct size for you and will give you information about using, inserting, and removing the diaphragm. Your health care provider will give you a prescription for the diaphragm.

Diaphragms may be purchased at a drugstore or clinic with a prescription. An examination costs from $0 to $200. Diaphragms average from $0 to $75. Spermicide gel, jelly, or cream costs from about $0 to $17 a kit.

Planned Parenthood works to make health care accessible and affordable. Some health centers are able to charge according to income. Most accept health insurance. If you qualify, Medicaid or other state programs may lower your health care costs. 

Call your local Planned Parenthood health center to get specific information on costs.
