Most Trojan condoms last about five years from the date of manufacture, though the exact timeframe depends on the material and whether the condom contains spermicide. Condoms with spermicide typically have a shorter shelf life, closer to three years. Every Trojan condom has a printed expiration date on both the outer box and the individual foil wrapper, so you never have to guess.
Shelf Life by Condom Type
Standard latex Trojan condoms, which make up the majority of their product line, carry an expiration date roughly five years out from manufacture. Non-latex options made from polyurethane or polyisoprene (like the Trojan Supra or BareSkin lines) also last about five years when stored properly, since the foil packaging limits oxygen exposure regardless of material.
Spermicidal condoms are the exception. The active ingredient breaks down faster than the latex itself, which is why these varieties expire sooner. If you’re buying Trojan condoms with spermicide, expect a shelf life closer to three years. Always check the date on the wrapper rather than assuming it matches the standard timeline.
What Actually Degrades a Condom
The biggest factor in condom lifespan is age. A study examining 20 lots of latex condoms found that age was the single best predictor of breakage during use, with a near-perfect statistical correlation. Brand new condom lots had a breakage rate of about 3.5 percent, while a lot that was 81 months old (nearly seven years) broke at a rate of 18.6 percent. That’s more than a fivefold increase.
Heat accelerates this process significantly. Research exposing condoms to different climates found that latex properties decline in a way that worsens exponentially with rising temperature, not just linearly. At average storage temperatures of 30°C (86°F) or lower, condoms in foil packaging held up reasonably well, but above that threshold, degradation sped up. Oxygen exposure is the other major culprit. Condoms stored in permeable packaging or left unwrapped lost their stretch and strength, while those sealed in foil with silicone lubricant and antioxidants in the latex formula resisted breakdown far better.
Freezing is equally damaging. Extreme cold makes latex brittle, and that damage persists even after the condom returns to room temperature.
Why Your Wallet Is the Worst Storage Spot
Keeping a condom in your wallet seems convenient, but it’s one of the fastest ways to ruin it. Your body heat keeps the condom at a consistently warm temperature, while sitting and moving creates constant bending and friction against the foil. Over days or weeks, this combination can create microscopic holes and tears in the latex that are invisible when you open the wrapper. The packaging may look perfectly fine, but the condom inside may no longer provide reliable protection against pregnancy or STIs.
The same logic applies to glove compartments, which can reach extreme temperatures in summer and winter, and to back pockets or anywhere the condom gets compressed repeatedly. A cool, dry drawer or nightstand is ideal. If you want to carry one with you, a hard-sided case or small tin protects it from friction and pressure.
How to Check if a Condom Is Still Good
Start with the expiration date. It’s printed directly on the foil wrapper, usually near the edge, and also on the box. If the date has passed, throw it away regardless of how it looks or feels.
Even if the date is still valid, inspect the condom before use. The foil wrapper should feel like it has a small air cushion inside, meaning the seal is intact. If the packaging feels flat, has visible tears, or looks like it’s been punctured, skip it. Once you open the wrapper, the condom itself should feel smooth, flexible, and evenly lubricated. Watch for these warning signs:
- Brittleness or stiffness: The latex should stretch easily. If it feels rigid or cracks when you unroll it, the material has degraded.
- Stickiness: A tacky or gummy texture means the latex is breaking down.
- Unusual smell: A strong or off-putting odor beyond the normal latex scent suggests chemical degradation.
- Discoloration: Any visible color change from what you’d normally expect is a red flag.
Does Using an Expired Condom Still Help?
An expired condom is better than no condom at all, but only barely. The 18.6 percent breakage rate found in aged condoms means roughly one in five will fail during use. That’s a substantial risk for both pregnancy prevention and STI protection. If an expired condom is your only option in the moment, using it still reduces risk compared to unprotected sex. But it shouldn’t be treated as reliable, and it’s worth following up with emergency contraception or STI testing depending on the situation.
The simplest way to avoid this scenario is to rotate your supply. Check expiration dates every few months and replace anything getting close. Condoms are inexpensive enough that tossing a few outdated ones is a minor cost compared to the consequences of a failure.
