Several birth control options work well without a condom, but your best choice depends on whether you need protection against pregnancy alone or against sexually transmitted infections too. Condoms are the only widely available method that does both reliably. Every alternative on this list either protects against pregnancy only or offers limited STI protection, so that tradeoff is worth understanding before you switch.
How Effectiveness Numbers Work
Every method below includes two numbers: “typical use” and “perfect use.” Typical use reflects how the method performs in real life, accounting for human error like forgetting a pill or inserting a device incorrectly. Perfect use reflects the rate when every instruction is followed flawlessly every time. The gap between these two numbers tells you how forgiving a method is. A condom, for comparison, has an 18% typical-use failure rate and a 2% perfect-use failure rate, meaning 18 out of 100 couples using condoms for a year will experience an unintended pregnancy under real-world conditions.
Long-Acting Reversible Methods (IUDs and Implants)
If preventing pregnancy is your main goal, long-acting reversible contraception is the most effective option available. These methods require a single appointment to place and then work for years without any daily effort, which virtually eliminates user error.
The hormonal IUD has a failure rate of just 0.2%, and the copper IUD’s rate is about 0.8%. Both are over 99% effective. The contraceptive implant, a small rod placed under the skin of the upper arm, is the single most effective reversible method at 0.05% failure. All three are comparable in effectiveness to permanent sterilization. They can be removed at any time if you want to become pregnant, and fertility typically returns quickly.
The copper IUD contains no hormones, which makes it a strong option if you want to avoid hormonal side effects. Hormonal IUDs release a small amount of hormone locally, which often lightens periods over time. None of these methods protect against STIs.
Hormonal Methods You Manage Yourself
The pill, the patch, and the vaginal ring all have a 9% typical-use failure rate and a 0.3% perfect-use rate. That gap reflects how easy it is to miss a pill, apply a patch late, or forget to swap a ring on schedule. If you’re confident you can stick to a routine, these methods are highly effective. If consistency is a challenge, a longer-acting method will serve you better.
The injectable shot is given every three months and has a 6% typical-use failure rate. Because you only need to remember it four times a year, there’s less room for error than with daily or weekly methods. All hormonal options prevent pregnancy only, with no STI protection.
Barrier Methods That Aren’t Condoms
If you prefer something non-hormonal that you use only when you have sex, a few barrier options exist.
The internal (female) condom is the closest substitute for a traditional condom because it also reduces STI risk, including HIV. It’s about 75% to 82% effective with normal use and 95% effective when used perfectly every time. It’s not considered quite as reliable as a male condom for STI prevention, but it’s the only alternative that offers meaningful protection against both pregnancy and infections.
The diaphragm is a shallow silicone cup that covers the cervix. It has a 12% typical-use failure rate and is used with spermicide. You insert it before sex and leave it in for at least six hours afterward. It requires a prescription and fitting, and it does nothing to prevent STIs.
The contraceptive sponge is a soft foam device containing spermicide that you insert before sex. It provides 24 hours of protection regardless of how many times you have sex during that window. For people who have never given birth, it’s about 88% effective. For those who have, effectiveness drops to about 80%. You need to leave it in for at least six hours after sex but must remove it within 30 hours. No STI protection.
The cervical cap works similarly to a diaphragm but is smaller and fits more snugly over the cervix. It’s used with spermicide and requires a prescription. Studies have found that the original Prentif cap matched the diaphragm in pregnancy prevention, but the newer FemCap did not quite reach the same effectiveness.
Non-Hormonal Vaginal Gel
A prescription vaginal gel is available that works by keeping the vagina’s natural acidity stable even when semen (which is alkaline) is present. This acidic environment slows and immobilizes sperm. The gel also forms a viscous barrier over the cervix. You apply it shortly before sex each time.
In a clinical trial of nearly 1,400 women, the seven-cycle pregnancy rate with typical use was 13.7%. That makes it less effective than hormonal methods but comparable to other on-demand options like diaphragms and sponges. Researchers are currently studying whether its acid-buffering properties might also help prevent chlamydia and gonorrhea, but those results aren’t confirmed yet.
Fertility Awareness Methods
Fertility awareness involves tracking your body’s signals to identify which days you can get pregnant and then avoiding unprotected sex on those days. Several approaches exist, and their effectiveness varies dramatically depending on the method and how carefully you follow it.
The symptothermal method, which combines daily temperature readings with cervical mucus observation, is the most effective. With correct use, its failure rate is just 0.4%, rivaling hormonal methods. Even with typical use, the rate is about 1.8%. Other approaches are less forgiving. The Standard Days Method (avoiding sex on days 8 through 19 of your cycle) has a typical-use failure rate of 12%. The Billings Ovulation Method, based on mucus patterns alone, comes in at 10.5% with typical use.
These methods require daily attention and a willingness to abstain or use another method during fertile windows. They work best for people with regular cycles who are motivated to learn the technique thoroughly. They provide zero STI protection.
Withdrawal
Pulling out before ejaculation is one of the oldest birth control methods and is more effective than its reputation suggests, though still far from reliable. With perfect use, the failure rate is 4%. With typical use, it jumps to 22%, largely because timing withdrawal consistently in the moment is difficult. It offers no protection against STIs, since pre-ejaculate fluid can carry infections.
Permanent Options
If you’re certain you don’t want children in the future, sterilization is the most effective long-term choice. Vasectomy has a failure rate of 0.03% to 0.05% and is performed through a small opening with no scalpel, minimal pain, and fast recovery. It does not affect hormone levels, sexual function, or long-term health. Studies have confirmed no increased risk of prostate cancer or other diseases.
Tubal ligation has a failure rate of about 1% over 10 years, varying by technique. It doesn’t affect hormones or periods. Both procedures are considered permanent, and while reversal is sometimes possible, it’s not guaranteed.
Emergency Backup Options
If you have unprotected sex or your chosen method fails, emergency contraception can reduce the chance of pregnancy after the fact. Two types of emergency pills are available. Both work best when taken as soon as possible and can be used up to five days after unprotected sex. Within the first three days, they perform similarly. Between days three and five, the prescription-only option (ulipristal acetate) is more effective, especially for people with a higher body weight.
The most effective emergency option is having a copper IUD placed within five days. It works as both an emergency measure and ongoing contraception for up to 10 years afterward.
The STI Gap
The biggest limitation of nearly every condom alternative is the lack of STI protection. Hormonal methods, IUDs, implants, diaphragms, sponges, fertility awareness, withdrawal, and sterilization do nothing to prevent infections like chlamydia, gonorrhea, herpes, or HIV. The internal condom is the only alternative that reduces STI transmission, though not as effectively as a standard external condom.
If STI risk is part of your situation, combining a highly effective pregnancy prevention method (like an IUD or implant) with a barrier method for infection protection gives you the strongest coverage on both fronts. For people in long-term mutually monogamous relationships where both partners have been recently tested, STI protection may be less of a concern, and the full range of alternatives becomes practical.
