Can a Yeast Infection Cause Infertility?

Let’s be real: most of us have typed something slightly panicked into Google at some point—like “Can a yeast infection make me infertile?”

You feel that familiar itch, maybe for the second or third time this year, and suddenly your mind spirals: Is this messing with my fertility? What if it’s already done damage?

Take a deep breath. You’re not alone in asking, and we’re here to give you the clear, comforting answer you deserve.

First, what is a yeast infection?

A yeast infection (also called vaginal candidiasis) happens when there’s an overgrowth of Candida, a type of fungus naturally present in the vagina. It can cause itching, burning, and a thick white discharge—but while annoying and uncomfortable, it’s also incredibly common.

Around 75% of women will experience at least one yeast infection in their lifetime. It’s not an STI, and it’s not your fault.

So… Can it affect fertility?

Here’s the short answer: a typical yeast infection won’t cause infertility.

Yeast infections are localised in the vaginal canal and don’t usually travel to the uterus, fallopian tubes, or ovaries. This means they don’t typically interfere with ovulation, egg quality, or implantation.

But there’s a little nuance worth understanding:

🧬 If they’re chronic or misdiagnosed…

Recurring yeast infections (more than 4 per year) can signal an underlying imbalance in your vaginal microbiome. This isn’t directly linked to infertility, but your microbiome plays a key role in vaginal health and even sperm survival.

Plus, what seems like a yeast infection could actually be bacterial vaginosis (BV), trichomoniasis, or STIs—some of which can impact fertility if left untreated. So if symptoms keep returning, a proper diagnosis matters.

Yeast infections & TTC: Are there any real risks?

If you’re trying to conceive (TTC), there are a few things to keep in mind:

• Discomfort during sex: Yeast infections can make intercourse painful, which might interrupt timed TTC attempts.

• pH imbalance: A disrupted vaginal pH can affect cervical mucus, which plays a role in helping sperm swim toward the egg.

• Medication timing: Antifungal treatments are usually safe, but always double-check if you’re actively TTC or undergoing fertility treatment.

Bottom line: yeast infections are rarely a direct cause of infertility, but they can make the process feel harder if they're frequent or unresolved.

When to talk to a doctor

• If you get yeast infections more than a few times a year

• If your symptoms don’t go away with over-the-counter treatment

• If you’re unsure whether it’s a yeast infection or something else

• If you’re TTC and feel confused or anxious about how this might affect your journey

You deserve peace of mind—and support that goes beyond Google.

Quick FAQ

Can a yeast infection affect my eggs or uterus?
Nope. It stays in the vaginal canal.

What if I get yeast infections during IVF?
Tell your doctor. It can be treated safely and usually doesn’t interfere with the cycle.

Could it affect sperm?
Only slightly, and mostly if it disrupts vaginal pH or mucus. It’s not a major risk.

Final Thoughts

Yeast infections are common and treatable—and they typically don’t affect your fertility long term. But if they’re recurring or not responding to treatment, they could be a sign of something deeper. Understanding your vaginal and reproductive health is an important step on any fertility path.
