Can Bacterial Vaginosis (BV) Affect Fertility?

If you've been diagnosed with bacterial vaginosis (BV) and you're trying to become pregnant, you may have found yourself asking an understandable question:

"Could BV be affecting my fertility?"

The honest answer is...

Possibly—but not usually in the way many people think.

Researchers have found that BV is more common in some people experiencing infertility, but that doesn't mean BV directly causes infertility.

Understanding the difference is important.

What Is BV?

Bacterial vaginosis is a common condition caused by a change in the normal balance of bacteria in the vagina.

It isn't caused by poor hygiene.

It isn't simply "an infection."

It's an imbalance in the vaginal microbiome.

Many women experience BV at some point in their lives.

For many, it clears with treatment and never returns.

For others, it becomes a recurring problem.

Does BV Cause Infertility?

Current evidence does not show that BV itself is a direct cause of infertility.

Many women with BV become pregnant naturally.

However...

Researchers have found associations between BV and certain reproductive health problems.

That doesn't mean BV causes them.

It means the relationship is more complex than we once thought.

What Does the Research Show?

Research suggests that BV may be associated with:

  • Pelvic inflammatory disease (PID)

  • Increased risk of some pregnancy complications

  • Reduced success in some fertility treatments

  • A higher rate of BV in women attending fertility clinics

Researchers are still investigating exactly why these associations exist.

At present, they cannot say that BV directly causes infertility.

Could BV Be a Sign That Something Else Is Going On?

Most women with BV do not have another underlying condition.

However...

If BV keeps returning despite treatment, it's reasonable to discuss this with your healthcare professional.

The important question isn't:

"Does BV mean I have endometriosis?"

Because the answer is usually no.

The better question is:

"Is there anything else we should consider now that this keeps recurring?"

Sometimes the answer will simply be:

"No."

Sometimes your healthcare professional may recommend further assessment.

Every situation is different.

My Story

For many years, I experienced recurrent bacterial vaginosis.

It was treated.

It improved.

Then it came back.

Again.

And again.

At the time, I accepted that recurrent BV was simply something I had to live with.

Years later, I discovered that I had bilateral hydrosalpinx caused by endometriosis.

Can I say recurrent BV caused my infertility?

No.

Can I say it caused endometriosis?

No.

The evidence doesn't support those conclusions.

What I do wonder is whether repeated symptoms of any kind deserve thoughtful review rather than simply repeated treatment.

That's one of the reasons I created this website.

Why Looking at the Bigger Picture Matters

One episode of BV isn't usually a cause for concern.

Neither are many repeated episodes for most women.

But recurring symptoms deserve context.

If you're also experiencing:

  • Difficulty becoming pregnant

  • Persistent pelvic pain

  • Painful periods

  • Recurrent urinary tract infections

  • Recurrent thrush

  • Pain during sex

...it may be helpful to discuss your whole health history with your healthcare professional rather than each symptom individually.

That doesn't mean they're connected.

It simply means patterns are sometimes easier to recognise when viewed together.

Questions Worth Asking

If you're trying to conceive and experiencing recurrent BV, you may wish to ask:

  • Is this definitely bacterial vaginosis?

  • Why do you think it keeps recurring?

  • Is there anything else that could explain my symptoms?

  • Given my fertility concerns, is any further assessment appropriate?

  • If the BV returns again, what would you recommend next?

These aren't questions designed to find a hidden diagnosis.

They're questions designed to help you understand your care.

Medical Words Made Simple

Bacterial Vaginosis (BV)

A change in the balance of the normal bacteria living in the vagina.

Microbiome

The community of helpful bacteria and other tiny organisms that naturally live in and on our bodies.

Pelvic Inflammatory Disease (PID)

An infection of the female reproductive organs that can sometimes lead to scarring if not treated promptly.

I Wish Someone Had Explained...

I wish someone had told me that treating BV and understanding why it kept returning weren't always the same thing.

Every course of antibiotics dealt with the immediate problem.

What I don't remember is anyone stepping back and asking,

"Has anything else been happening over the years?"

Perhaps the answer would still have been no.

Perhaps it would have led to further questions.

I'll never know.

But I do know that recurring symptoms deserve thoughtful conversations.

Key Takeaways

  • BV is common and usually treatable.

  • Current evidence does not show that BV directly causes infertility.

  • Recurrent BV is common, but persistent symptoms deserve review.

  • Looking at your overall health history can sometimes help guide future investigations.

  • Understanding your healthcare is just as important as receiving treatment.

Hope

If you're trying to conceive and struggling with recurrent BV, please don't assume the worst.

Most women with BV do not experience infertility because of it.

If symptoms continue, don't be afraid to return to your healthcare professional and continue the conversation.

Knowledge isn't about expecting bad news.

It's about understanding your own health.

A Gentle Reminder

Your body whispers before it screams.

Not every whisper means something serious.

But persistent symptoms deserve thoughtful conversations, informed questions and healthcare professionals who are willing to listen.

If something doesn't feel right, don't be afraid to ask again.
