Fact Check: Can Condoms Cause BV or Yeast Infections?

Condoms are great: they're affordable, accessible, highly effective in preventing pregnancy, and they're the only form of birth control that also protects you from sexually transmitted infections (STIs).

So there's nothing more frustrating than being responsible and practicing safe sex, only to be "rewarded" with a vaginal infection right after. It's a pretty natural leap to assume the condom itself is to blame, especially if you've never had issues before or only seem to get symptoms after protected sex. 

Condoms don’t cause bacterial vaginosis (BV) or yeast infections — as a matter of fact, they reduce your risk of developing either infection. However, some ingredients commonly added to condoms (like lube or spermicides) can disrupt your microbiome, causing irritation and potentially triggering an infection. 

But before you swear off condoms altogether, it's worth understanding what's actually going on, because the real cause might be something else entirely.

Key takeaways

• Condoms are staples of safe, satisfying sex. They can help reduce the risk of STIs and other vaginal infections — the key is finding the right one. 
• Sex can be a trigger for yeast infections and BV, whether or not you use a condom.
• Glycerin, flavors, spermicides, and latex are ingredients commonly used in condoms and lube. They may cause irritation in some people, but there’s no strong evidence that condoms themselves cause yeast infections.
• If you often get an infection after having protected sex, try switching up the condoms and lube you use. As a general rule, try to avoid anything with flavors, scents, or spermicide.

Can condoms cause yeast infections or BV?

The short answer is no, condoms aren’t a direct cause of vaginal infections like BV or yeast infections. In fact, consistent condom use can actually help lower your risk for vaginal infections.  However, there are a few caveats to keep in mind. 

How condoms help prevent BV

Condoms act as a barrier between the genitals, preventing viruses and bacteria from entering the vagina. Condoms also collect semen, which can disrupt your vaginal pH as well as carry BV-causing bacteria.

Not only do they stop the spread of STIs, but condoms can prevent vaginal infections, too. A 2008 systematic review looked at the sexual risk factors associated with BV and found that condom use was protective against BV.

One study found that condom use reduces the risk of BV by 45%. Meanwhile, a more recent study found that consistent condom use increases the colonization of Lactobacillus crispatus in the vagina, a protective species of vaginal bacteria that helps guard the microbiome against BV-causing bacteria.

This protective effect makes more sense in light of newer research on how BV spreads. A study published in The New England Journal of Medicine (NEJM) found that men can carry and pass BV-associated bacteria to their female partners during sex, and that treating both partners significantly reduces BV recurrence. This is a shift from the traditional view of BV as purely a vaginal imbalance, and it helps explain why barrier protection like condoms can play a meaningful role in prevention, not just for STIs, but for BV itself.

The Centers for Disease Control and Prevention (CDC) recommends using condoms to prevent BV. So if you know you're prone to infection, using condoms can help you enjoy sex without worrying about how it's affecting your vaginal microbiome.

Having said that, there are some factors to consider. Sex can increase your chances of developing a vaginal infection, whether or not you use a condom, and while condoms alone don't increase your risk for vaginal infections, sometimes they contain added ingredients that might.

How to choose a microbiome-friendly condom 

While condoms are extremely beneficial for protecting the vaginal microbiome, not all condoms are created equal. It is important to consider what other ingredients may be coating the condom. 

For example, some condoms have spermicide, a chemical that stops sperm from reaching the egg. Most spermicides contain an ingredient called Nonoxynol-9, which can irritate the vaginal tissue. Another issue with Nonoxynol-9 is that, aside from killing sperm, some research suggests it might kill the protective bacteria in your vaginal microbiome, too. 

Additionally, while flavored condoms are designed to make oral sex more palatable (so to speak), they’re not really meant to be used for vaginal sex. If you’ve been using flavored condoms during intercourse, it may disrupt your vaginal microbiome due to the relationship between sugar and yeast.   

Yeast infections are typically caused by an overgrowth of a fungus called Candida albicans. Candida can be present in your vagina without causing any issues, but having too much of it is what triggers the burning, itching, and white, clumpy discharge that are trademark symptoms of a yeast infection. 

Remember that BV, yeast infections, and STIs can still be transmitted through oral sex, so really, we should all be using condoms or dental dams when giving and receiving oral sex. Whether or not you opt for a flavored option is entirely down to personal taste (pun intended). 

But as a precaution, if you’re struggling with yeast infections, perhaps stay away from flavored condoms altogether. 

Can lube cause yeast infections?

Some lube formulas contain ingredients that can disrupt your vaginal microbiome. 

Glycerin is a common, problematic ingredient to look out for in lube. Glycerin is a sugar alcohol that acts as a humectant (meaning it helps retain moisture) and is often found in different lubes, especially flavored or warming ones. 

Like with flavored condoms, glycerin can act as food for Candida albicans and result in a vaginal yeast infection. This doesn’t mean that everyone who uses glycerin-based lube will get one, but if you already suffer from recurring yeast infections, you may want to be mindful. 

Some condoms also come with lube on them. If you find that you often get a yeast infection after using pre-lubricated condoms, the issue may be the lube rather than the condom itself. 

Similar to how skin products with lots of ingredients may be irritating to the skin, many lubricants have a laundry list of ingredients that may cause irritation in some people, or even potentially an allergic reaction. Opting for lubricants with minimal ingredients may be beneficial.  

Yeast infection vs latex sensitivity 

Allergies and sensitivity to latex condoms are fairly rare, but even a mild reaction can irritate the vagina and cause symptoms similar to a yeast infection, like itching, burning, and swelling. However, an allergic reaction isn’t usually accompanied by unusual discharge. 

If you suspect you have a sensitivity to latex condoms, some alternatives include polyurethane or polyisoprene condoms, lambskin condoms, or female condoms. 

A full-blown latex allergy can also cause hives, difficulty breathing, and anaphylactic shock. If you experience any of these symptoms after using a latex condom, call 911.

TL;DR

The bottom line is that if you feel like your vagina is on fire after sex (but not in a good way), it could be down to the type of lube or condoms you’re using, but condoms aren’t a direct cause of vaginal infections. In fact, they can help prevent yeast infections and BV.  

FAQs about condoms, BV, and yeast infections

Can condoms throw your pH balance off?

Condoms themselves don't typically throw off your vaginal pH. In fact, by preventing semen (which is alkaline) from entering the vagina, they can help keep your pH more stable. That said, condoms with added ingredients like spermicide or flavoring can cause irritation that may indirectly affect your microbiome balance.

Why do latex condoms give me yeast infections?

Latex itself doesn't typically cause yeast infections. What you're experiencing may actually be a latex sensitivity, which can mimic yeast infection symptoms like itching and irritation. It's also possible that added ingredients on the condom, like flavoring or lube, are disrupting your microbiome and allowing Candida to overgrow. If this keeps happening, try a condom without added ingredients, like an unflavored, non-lubricated option, or consider polyurethane or polyisoprene alternatives.

Can latex condoms cause BV?

No, latex condoms aren't a cause of BV. Condom use is actually associated with a lower risk of BV. If you notice BV symptoms after using condoms, it's more likely linked to other factors, like added spermicide, or simply that sex itself (with or without a condom) can be a trigger for some people.
