What Is a Female Condom and How Does It Work?

Looking for a hormone-free way to protect yourself during sex? A female condom, also known as an internal condom, could be an option worth exploring. This discreet contraceptive method helps prevent pregnancy while also reducing the risk of sexually transmitted infections (STIs).

Unlike traditional condoms, female condoms are worn inside the body, giving you more control over your protection. But how exactly do they work, and how effective are they? Understanding the benefits, correct use and potential risks can help you decide whether a female condom is right for your sex life.

What is a female condom?

A female condom (also called an internal condom) is a soft, loose-fitting pouch that is inserted into the vagina before sex. Usually made from nitrile, it lines the vaginal walls and covers part of the vulva. Unlike external condoms, which are worn over the penis or sex toys, internal condoms create a protective barrier inside the body. This helps prevent sperm from entering the vagina, reducing the risk of pregnancy and sexually transmitted infections (STIs). Internal condoms can also be used for anal sex, although it's important to check the product instructions, as not all are approved for this purpose.

Most female condoms have two flexible rings:

• The inner ring: Located at the closed end of the pouch, it helps guide the condom into position and keeps it in place.

• The outer ring: Stays outside the vaginal opening, helping keep the condom in position and providing additional coverage.

Why might you choose a female condom?

Female condoms offer several benefits, particularly if you want more control over your sexual health:

• Pregnancy prevention: They create a barrier that prevents sperm from reaching an egg.

• STI protection: They reduce the risk of sexually transmitted infections by limiting contact with bodily fluids and some skin-to-skin contact.

• Easy access: They're available without a prescription.

• Hormone-free and non-permanent: They provide protection without hormones or long-term effects on fertility.

How effective is a female condom?

Internal condoms are 95% effective at preventing pregnancy when used correctly every time. When used incorrectly or inconsistently, effectiveness drops to around 79%, meaning approximately 1 in 5 women who rely on them for contraception will become pregnant within a year (NHS, 2024).

It's important to remember that no barrier method provides 100% protection against pregnancy or STIs. Depending on the infection, STIs can spread through vaginal, anal or oral sex, as well as through skin-to-skin contact in areas not covered by a condom (National Library of Medicine, 2025).

Combining consistent condom use with regular sexual health testing can offer extra peace of mind and help you take a proactive approach to your sexual health.

How do you use a female condom correctly?

Using a female condom may feel unfamiliar at first, but insertion generally becomes easier with practice. Following these steps can help you use it safely and effectively.

1. Check the packaging and expiry date. Make sure the condom hasn't expired and that the packaging is intact. Check for visible damage and open it carefully without using your teeth or sharp objects.

2. Find a comfortable position. You can lie down, squat or stand with one foot raised. Choose whichever position makes insertion easiest.

3. Insert the inner ring. Squeeze the thicker inner ring at the closed end and gently insert it into your vagina. Use your finger to push it as far as it will comfortably go, towards your cervix. Make sure the condom isn't twisted and the outer ring stays outside your vagina, covering the vaginal opening.

4. Use lubricant if needed. A compatible lubricant can help reduce friction and prevent the condom from slipping or tearing. Check the packaging for suitable lubricants.

5. Guide the penis into the pouch. During sex, make sure the penis enters the condom rather than slipping between the condom and the vaginal wall. Stop if the condom moves out of place or the outer ring gets pushed inside.

6. Remove the condom carefully. After sex, gently twist the outer ring a few times to prevent semen from leaking out. Slowly pull the condom out and dispose of it in a bin, not the toilet.

Always use a new internal condom for each sexual encounter.

What are the disadvantages and common mistakes of internal condoms?

While internal condoms offer several benefits, there are some potential drawbacks and common mistakes to be aware of:

• Availability and cost: Internal condoms can be harder to find and more expensive than external condoms.

• Discomfort: Some people may experience irritation or discomfort due to improper positioning or sensitivity to the material.

• Disruption during sex: Insertion may take practice, and some people find that internal condoms make noise during sex.

• Incorrect timing: Inserting the condom after genital contact has already occurred can reduce protection.

• Slipping or tearing: The condom may move out of place, tear or fail if the penis enters outside the pouch.

• Using multiple condoms: Never use two internal condoms together or combine an internal condom with an external condom, as friction can cause tearing.

• Incompatible lubricants: Always check the product instructions to see which lubricants are compatible with your internal condom, as this depends on the material it's made from.

What should you do after a condom fails or you're unsure it worked?

If a female condom breaks, slips or doesn't stay in place, there are practical steps you can take to protect your sexual health.

• Consider emergency contraception: If pregnancy is a concern, seek advice promptly. Options are available approx. within three days, depending on the method.

• Avoid internal washing: Douching won't prevent pregnancy or STIs and may cause irritation.

• Get tested for STIs: Test after the appropriate window period, even without symptoms. Timing depends on the infection.

• Act quickly after possible HIV exposure: Seek medical advice immediately, as preventive treatment (PEP) must start within 72 hours.

• Watch for symptoms: Look out for unusual discharge, irritation, pain or other changes. Keep in mind that many STIs cause no noticeable symptoms, making testing important even if you feel well.

If symptoms develop or you're uncertain about your risk, speak to your GP or a sexual health clinic for personalised advice.
