Several effective alternatives to condoms exist for preventing pregnancy, ranging from long-acting devices to daily pills to non-hormonal options. The right choice depends on whether you need protection from pregnancy alone or from sexually transmitted infections as well, since most condom alternatives only address pregnancy. Here’s a practical breakdown of what’s available, how well each option works, and what trade-offs to expect.
Long-Acting Methods: IUDs and Implants
If your main concern is pregnancy prevention, long-acting methods are the most effective options available. A hormonal IUD has a typical use failure rate of just 0.2%, and a copper IUD sits at 0.8%. The contraceptive implant, a small rod placed under the skin of your upper arm, is even more effective at 0.05%. For comparison, male condoms fail about 13% of the time with typical use.
These methods work for years (3 to 10, depending on the type), require no daily effort, and can be removed whenever you want. The copper IUD is hormone-free, which matters if you’re trying to avoid hormonal side effects. Both IUDs and implants require a clinic visit for placement and removal, but once they’re in, there’s essentially nothing to remember or do. Neither protects against STIs.
The Pill: Prescription and Over-the-Counter
Birth control pills have a typical use failure rate of about 9%, mostly because people miss doses or don’t take them at the same time each day. With perfect use, that drops to 0.3%. The gap between those numbers tells you something important: pills work well only if you’re consistent.
An over-the-counter progestin-only pill is now available in the U.S. without a prescription. Its perfect use effectiveness is about 98%, but it has a narrow timing window. If you’re more than 3 hours late taking it, you need a backup method like condoms until you’re back on track. Combined pills (which contain both estrogen and progestin) are available by prescription and offer a slightly more forgiving timing window.
Internal Condoms
Internal condoms (sometimes called female condoms) are the closest direct swap for a standard condom. They’re worn inside the vagina or rectum and create a physical barrier that catches both sperm and infectious fluids. Like external condoms, they provide some protection against STIs spread through genital fluids, such as gonorrhea and chlamydia, though they’re less effective against infections spread through skin-to-skin contact, like herpes or syphilis.
Internal condoms are available without a prescription at most pharmacies. They’re a good option if a latex allergy makes external condoms uncomfortable, since internal condoms are typically made from nitrile. The main drawback is that they take a bit of practice to insert correctly, and some people find them less convenient.
Diaphragms and Cervical Caps
A diaphragm is a shallow silicone cup that covers the cervix, blocking sperm from reaching the uterus. With perfect use, diaphragms prevent pregnancy about 94% of the time. With typical use, that drops to 87%. They must always be used with spermicide, a gel or cream that immobilizes sperm on contact.
You’ll need a prescription and possibly a fitting appointment, since diaphragms come in sizes. If your weight changes significantly or you’ve recently been pregnant, you may need a different size. The diaphragm goes in before sex and stays in place for at least six hours afterward. It offers no meaningful STI protection.
Non-Hormonal Vaginal Gel
A prescription vaginal gel is available that works by lowering the pH inside the vagina, which slows sperm down and reduces their ability to move. You apply it within an hour before sex. It’s hormone-free and doesn’t require a fitting.
The trade-off is effectiveness. In clinical trials, the estimated failure rate was about 27.5 pregnancies per 100 women per year, making it significantly less reliable than most other methods. It works best when combined with another form of contraception, such as fertility awareness or withdrawal, rather than used alone. It does not protect against STIs.
Fertility Awareness Methods
Fertility awareness involves tracking your menstrual cycle to identify the roughly nine or more days per month when you can get pregnant, then either avoiding sex or using a barrier method during that window. Tracking methods include monitoring basal body temperature, checking cervical mucus, or using calendar calculations.
Typical use failure rates range widely, from 2% to 23%, depending on the specific method and how carefully you follow it. The most effective approaches combine multiple indicators (temperature plus mucus, for example). This method requires daily attention, works best with regular cycles, and offers zero STI protection. It’s free, though, and entirely non-hormonal.
Withdrawal
Withdrawal (pulling out before ejaculation) is one of the oldest and most commonly used alternatives to condoms. With perfect use, it fails about 4% of the time, which is better than many people expect. The problem is that perfect use is hard to achieve consistently. With typical use, the failure rate jumps to 22%, meaning roughly 1 in 5 couples relying on withdrawal will experience an unintended pregnancy within a year.
Withdrawal provides no STI protection and relies entirely on the withdrawing partner’s timing and self-control. It’s most reasonable as a backup or supplement to another method rather than a primary strategy.
Emergency Contraception
If you’ve already had unprotected sex, emergency contraception can reduce the chance of pregnancy after the fact. Two main pill options exist: one available over the counter and one by prescription. Both should be taken as soon as possible, ideally within 72 hours, though they can work up to 120 hours (5 days) after sex. The prescription option is more effective in that 72-to-120-hour window. A copper IUD can also be inserted as emergency contraception within 5 days and is the most effective emergency option available.
STI Protection Without a Condom
This is where most condom alternatives fall short. Pills, IUDs, implants, diaphragms, and fertility awareness do nothing to prevent sexually transmitted infections. If STI protection matters to you, a few pharmaceutical options now exist, though none are as broadly protective as condoms.
For HIV specifically, a daily preventive medication called PrEP lowers the risk of getting HIV from sex by about 99% when taken correctly. It’s available by prescription and is covered by most insurance plans in the U.S. PrEP protects only against HIV, not other infections.
For bacterial STIs like syphilis, chlamydia, and gonorrhea, a newer strategy called doxy-PEP involves taking an antibiotic within 72 hours after sex. In large clinical trials, this approach reduced syphilis and chlamydia infections by more than 70% and gonorrhea infections by roughly 50%. The CDC issued clinical guidelines for doxy-PEP in 2024, currently recommending it for men who have sex with men and transgender women who are at increased risk. It requires a prescription and ongoing medical supervision.
If you’re moving away from condoms with a partner, getting tested together for STIs is the most straightforward way to reduce risk. Combining a highly effective contraceptive method with STI testing (and PrEP if HIV risk is a concern) covers most of the ground that condoms cover, just with more planning upfront.
