1. What Is a Diaphragm?

A diaphragm is a barrier method of birth control designed for women. It’s a reusable, dome-shaped cup made of silicone that is inserted into the vagina to prevent pregnancy. Diaphragms work by covering the cervix, physically blocking sperm from entering the uterus. To enhance its effectiveness, it is typically used with spermicide, a chemical substance that kills sperm.

1.1. How Does a Diaphragm Work as Birth Control?

The diaphragm serves as a physical barrier, preventing sperm from entering the uterus. Here’s how it works:

Barrier: The diaphragm is inserted into the vagina and positioned to cover the cervix completely.
Spermicide: Spermicide is applied to the diaphragm before insertion. This chemical kills sperm, providing an additional layer of protection.
Prevention: By covering the cervix and using spermicide, the diaphragm prevents sperm from reaching and fertilizing an egg.

1.2. What Materials Are Diaphragms Made Of?

Modern diaphragms are typically made of medical-grade silicone, which is flexible, durable, and less likely to cause allergic reactions than the latex materials used in older versions. The silicone is non-porous, making it easy to clean and maintain.

1.3. How Do Diaphragms Compare to Cervical Caps?

Both diaphragms and cervical caps are barrier methods of birth control, but they differ in several ways:

Size and Shape: Diaphragms are larger and dome-shaped, while cervical caps are smaller and shaped like a thimble.
Placement: Diaphragms cover the entire cervix and part of the vaginal wall, while cervical caps fit snugly over the cervix only.
Spermicide Use: Both require spermicide, but diaphragms generally require more spermicide than cervical caps.
Effectiveness: Diaphragms are generally considered more effective than cervical caps, particularly for women who have given birth.
Prescription: Both require a prescription and fitting by a healthcare provider.

2. How Effective Is a Diaphragm?

The effectiveness of a diaphragm as a birth control method depends on consistent and correct use. According to the CDC, with typical use, about 12 out of 100 women will get pregnant each year using a diaphragm. With perfect use, this number drops to about 6 out of 100 women.

2.1. What Factors Influence the Effectiveness of a Diaphragm?

Several factors can influence how well a diaphragm works:

Consistent Use: Using the diaphragm every time you have sex is crucial.
Correct Insertion: The diaphragm must be properly positioned to cover the cervix completely.
Spermicide Use: Using spermicide with each act of intercourse enhances the diaphragm’s effectiveness.
Fit: The diaphragm must be correctly fitted by a healthcare provider.
Replacement: The diaphragm should be replaced every two years, or if you have gained or lost a significant amount of weight, or after childbirth.

2.2. How to Properly Insert a Diaphragm?

Correct insertion is critical for the diaphragm to be effective. Here’s a step-by-step guide:

Wash Your Hands: Always wash your hands with soap and water before handling the diaphragm.
Apply Spermicide: Place about a tablespoon of spermicide into the dome of the diaphragm and spread some around the rim.
Find a Comfortable Position: You can either stand with one leg up on a chair, squat, or lie down.
Insert the Diaphragm: Hold the diaphragm between your thumb and fingers, squeezing the rim together. Insert it into your vagina like a tampon.
Position the Diaphragm: Push the diaphragm along the back wall of your vagina as far as it will go. The front rim should tuck behind your pubic bone.
Check Placement: You should be able to feel your cervix through the dome of the diaphragm. If you can’t feel it, the diaphragm may not be in the correct position.

2.3. What Are Common Mistakes to Avoid When Using a Diaphragm?

Avoiding common mistakes can significantly improve the effectiveness of the diaphragm:

Not Using Spermicide: Always use spermicide with the diaphragm, and apply more each time you have intercourse.
Incorrect Placement: Ensure the diaphragm covers the cervix completely.
Not Checking the Fit Regularly: Have your healthcare provider check the fit annually, or after significant weight changes or childbirth.
Leaving It In Too Long: Do not leave the diaphragm in for more than 24 hours to reduce the risk of infection.
Using Oil-Based Products: Avoid using oil-based lubricants or vaginal creams, as they can damage the diaphragm.

3. Benefits and Drawbacks of Using a Diaphragm

Like all birth control methods, the diaphragm has its advantages and disadvantages. Understanding these can help you decide if it is the right choice for you.

3.1. What Are the Advantages of Choosing a Diaphragm?

Non-Hormonal: The diaphragm is a non-hormonal method, making it suitable for women who cannot or prefer not to use hormonal birth control.
User-Controlled: You have control over when and how you use it.
Reusable: Diaphragms are reusable for up to two years, making them a cost-effective option.
Can Be Inserted in Advance: It can be inserted up to two hours before intercourse.
Does Not Affect Fertility: It does not affect your future fertility.

3.2. What Are the Disadvantages of Using a Diaphragm?

Requires Planning: You must remember to insert it before intercourse.
Requires Spermicide: Spermicide can be messy and may cause irritation for some women.
Lower Effectiveness: It has a higher failure rate than some other methods, such as IUDs or hormonal birth control.
Requires a Prescription and Fitting: You need to see a healthcare provider for a prescription and fitting.
No STI Protection: It does not protect against sexually transmitted infections (STIs).

3.3. Can a Diaphragm Protect Against STIs?

No, a diaphragm does not protect against sexually transmitted infections (STIs). If you are at risk of STIs, it is essential to use condoms in addition to the diaphragm. Consistent and correct use of condoms can significantly reduce the risk of STI transmission.

4. Who Is a Diaphragm Suitable For?

A diaphragm can be a suitable birth control option for women who:

Prefer a non-hormonal method.
Are comfortable inserting and removing it.
Are in a monogamous relationship or use condoms for STI protection.
Want a user-controlled method.

4.1. What Are the Contraindications for Using a Diaphragm?

There are certain situations where a diaphragm may not be the best choice:

History of UTIs: Women with frequent urinary tract infections (UTIs) may experience more UTIs with diaphragm use.
Allergy to Silicone or Spermicide: An allergy to either material would make this method unsuitable.
Abnormal Vaginal Shape: Certain anatomical conditions may make proper fitting difficult.
High Risk of STIs: If you are at high risk of STIs and not consistently using condoms, a diaphragm is not recommended.

4.2. Can You Use a Diaphragm After Giving Birth?

Yes, but you will need to be refitted. Pregnancy and childbirth can change the size and shape of your vagina, so a new fitting is necessary to ensure the diaphragm is effective. It is generally recommended to wait at least six weeks after giving birth before getting refitted.

4.3. How Does Weight Change Affect Diaphragm Fit?

Significant weight gain or loss can affect the fit of your diaphragm. If you experience a weight change of 10 pounds or more, it is essential to see your healthcare provider for a refitting to ensure it still fits correctly.

5. Obtaining and Caring For Your Diaphragm

Obtaining a diaphragm requires a visit to a healthcare provider for a prescription and fitting. Proper care ensures its effectiveness and longevity.

5.1. How Do I Get a Prescription for a Diaphragm?

To get a prescription, schedule an appointment with your gynecologist, family doctor, or a family planning clinic such as Planned Parenthood. During the visit, the healthcare provider will discuss your medical history, perform a pelvic exam, and determine the correct size for your diaphragm.

5.2. How Is a Diaphragm Fitted?

The fitting process involves a pelvic exam to measure the distance from behind the pubic bone to the back of the vagina. The healthcare provider will insert different sizes of diaphragms to find the one that fits best. They will also teach you how to insert and remove the diaphragm correctly.

5.3. What Is the Proper Way to Clean and Store a Diaphragm?

Proper cleaning and storage are essential for maintaining the diaphragm’s integrity and preventing infections:

Wash After Each Use: Remove the diaphragm and wash it with mild soap and warm water.

Air Dry: Allow the diaphragm to air dry completely before storing it.
Store in Its Case: Store the diaphragm in its case in a cool, dry place away from direct sunlight and extreme temperatures.
Avoid Oil-Based Products: Do not use oil-based lubricants, vaginal creams, or powders on the diaphragm, as they can damage the material.

6. Potential Side Effects and Risks

While diaphragms are generally safe, there are potential side effects and risks to be aware of.

6.1. What Are the Common Side Effects of Using a Diaphragm?

Irritation: Spermicide can cause irritation of the vagina or surrounding skin in some women.
Allergic Reactions: Some women may be allergic to the silicone in the diaphragm or the chemicals in spermicide.
Increased UTIs: Diaphragm use can increase the risk of urinary tract infections (UTIs).

6.2. Can a Diaphragm Cause Urinary Tract Infections (UTIs)?

Yes, diaphragm use has been linked to an increased risk of UTIs. This is because the diaphragm can put pressure on the urethra, making it difficult to empty the bladder completely. Bacteria can then grow in the residual urine, leading to an infection. If you experience frequent UTIs, discuss alternative birth control methods with your healthcare provider.

6.3. What Are the Signs of an Allergic Reaction to a Diaphragm or Spermicide?

Signs of an allergic reaction may include:

Itching: Intense itching in the vaginal area.
Burning: A burning sensation during or after intercourse.
Redness: Redness or swelling of the vulva or vagina.
Rash: A rash or hives on the skin.
Difficulty Breathing: In rare cases, a severe allergic reaction (anaphylaxis) can cause difficulty breathing and requires immediate medical attention.

If you experience any of these symptoms, discontinue use and consult your healthcare provider.
