BV Is Not an STI (But Here's Why We Need to Talk About It Like One).
Bacterial vaginosis isn't classified as a sexually transmitted infection. But the science is shifting, and the conversation needs to catch up. Here's what every woman needs to know about BV, sexual activity, and the hidden link to your overall health.
Here's a question that's been quietly debated in medical circles for years: Is bacterial vaginosis a sexually transmitted infection? The official answer is no. But read the fine print, and you'll find a more complicated truth: BV is associated with sexual activity. It increases your susceptibility to other STIs. And for the one in three women who will experience it, the question of how they got it—and how to stop it coming back—is anything but simple.
April is STI Awareness Month, a time when we talk openly about testing, prevention, and destigmatising sexual health. But there's one condition that sits in a grey area: bacterial vaginosis. It's the most common cause of abnormal vaginal discharge in women of childbearing age, affecting up to 29 percent of women globally. Yet it's often left out of STI conversations, leaving women confused about transmission, recurrence, and how to protect themselves.
This post is for the women who've been on the BV merry-go-round. The ones who've taken the antibiotics, felt better for a week, and then watched the symptoms creep back. Let's talk about what the latest science says, why your sexual health matters beyond the test results, and how post-intimacy care fits into the bigger picture.
What the Latest Science Says About BV
Bacterial vaginosis isn't like other infections. There's no single causative agent—it's a complex shift in your vaginal microbiota, a move away from protective Lactobacillus species toward a diverse mix of anaerobic bacteria. This disruption causes a rise in vaginal pH, leading to that characteristic thin, greyish discharge and fishy odour.
Current medical guidelines are clear: BV is not classified as an STI, and partner treatment is not routinely needed. But they also note something crucial: BV is associated with sexual activity and can coexist with STIs. This means that if you have BV, you should also be tested for chlamydia, gonorrhoea, and other STIs—especially if you have risk factors like a new partner, multiple partners, or symptoms suggesting something more serious.
The sexual health community is increasingly recognising that while BV may not meet the strict definition of an STI, its connection to sexual activity is undeniable. Research shows that BV prevalence increases dramatically after first sexual encounter, that new and multiple partners increase risk, and that condom use decreases risk. The evidence strongly supports sexual transmission of BV-associated bacteria.
The Recurrence Problem: Why It Keeps Coming Back
If you've had BV once, you know the frustration. Studies show recurrence rates are high, and many women cycle through multiple rounds of antibiotics without lasting relief. Why? Because antibiotics treat the bacterial overgrowth, but they don't address the underlying vulnerability—or the triggers that keep tipping your system out of balance.
Common recurrence triggers include:
-
New or multiple sexual partners
-
Semen exposure (semen has a basic pH that can neutralise your protective acidity)
-
Douching or using harsh intra-vaginal products
-
Anything that disrupts your vaginal microbiome
This is where the conversation needs to go beyond antibiotics. Treating the infection is step one. Supporting your body to stay balanced afterward is step two, three, and four.
Real Life Story:
"I felt like I was constantly managing my body instead of living in it," Sarah told me. She'd had BV three times in two years. Each time, the antibiotics worked, and each time, the symptoms returned—usually after sex. Her doctor never mentioned that semen could be a trigger. She was using scented wipes because she felt "unclean." She was caught in a cycle of treatment and recurrence, with no one explaining how to break it.
When she started using Après after sex—not as a treatment, but as a way to gently remove semen and fluids before they could disrupt her pH—something shifted. She stopped the scented wipes. She started paying attention to what her body needed. And for the first time in years, she went six months without a recurrence.
The Après Connection: A Tool for Breaking the Cycle
If BV is triggered by factors like semen exposure and disrupted pH, then managing those triggers is a logical part of prevention. This is where Après enters the conversation.
Après is not a treatment. It's not a douche. It's a soft, medical-grade sponge designed to gently absorb fluids after sex. For women prone to BV, this matters because:
-
It removes semen quickly. Semen has a basic pH that can temporarily neutralise your vagina's protective acidity. By absorbing it promptly, you're removing a key trigger before it can cause trouble.
-
It's non-chemical. Unlike douches or scented wipes that strip away good bacteria, Après works mechanically. It doesn't disrupt your microbiome—it just clears the stage so your body can do its job.
-
It supports your routine. Used consistently after sex, it becomes part of a prevention strategy that works alongside antibiotics when you need them.
Your Top Questions Answered!
1. "If I have BV, do I need to tell my partner?"
Yes. While partner treatment isn't routinely recommended, BV is associated with sexual activity, and partners can carry BV-associated bacteria. Having an open conversation allows you both to consider practices that might reduce recurrence risk—like using condoms or managing semen exposure.
2. "Can I get BV from my partner if they don't have symptoms?"
The evidence suggests that BV-associated bacteria can be present on male penile skin, in semen, and in the urethra. While men don't get BV, they can be carriers. This is why new or multiple partners increase your risk.
3. "How is Après different from douching?"
Douching is actively discouraged—it disrupts your vaginal microbiome and increases BV risk. Après is a mechanical tool, not a chemical cleanser. It gently absorbs fluids at the source without stripping your protective bacteria. It's about removing triggers, not scrubbing your ecosystem clean.
4. "Should I use Après if I'm being treated for BV?"
If you're in the middle of treatment, follow your doctor's advice. Some treatments involve intravaginal creams or gels that need time to work. But once treatment is complete, using Après after sex can help remove semen and other fluids that might trigger recurrence.
Your 4-Step Guide to Breaking the BV Cycle
-
Complete Your Treatment: If you're prescribed antibiotics, finish the full course—even if symptoms improve early.
-
Identify Your Triggers: Keep a simple log. Does recurrence happen after sex? After a new partner? After using scented products? The pattern will tell you what to address.
-
Protect Your Microbiome: Use condoms to reduce exposure to new bacteria and semen. Avoid douching and scented products. Consider using Après after sex to gently absorb fluids before they can disrupt your pH.
-
Talk to Your Provider: If recurrence persists, ask about other strategies—including whether your partner might benefit from condom use or if probiotics could support your microbiome.
