Can BV Cause Infertility? 

Table of Contents

Bacterial vaginosis, or BV, is so common that it’s easy to think it’s no big deal. Sure, it’s a nuisance, and the symptoms can be uncomfortable and even embarrassing, but beyond that, it’s not actually harmful. Is it? 

While we never want to play on scare tactics, it is our mission to share the scientific truth about vaginal health, and the truth about BV is that, especially if left untreated, it can lead to long-term health consequences, including infertility. Let’s dive into why that is and how you can prevent it.

Understanding Bacterial Vaginosis (BV)

An image with the title ‘What is BV?’ shows an illustration of bacteria and explains that bacterial vaginosis (BV) is a common vaginal infection caused by an imbalance of bacteria in the vagina. Symptoms include increased thin, gray-ish vaginal discharge with a ‘fishy’ smell, itchiness, and burning during urination or intercourse

To understand how BV can lead to infertility, we need to understand how it impacts your vaginal health more generally. What is BV?

Bacterial vaginosis is a common vaginal infection caused by an imbalance of bacteria in the vagina. Basically, bad bacteria have overtaken your vaginal microbiome, causing infection1, and generally, the reason the bad bacteria were able to overtake your vaginal microbiome is because, for some reason, there was not enough good Lactobacillus bacteria to stop it. In a healthy vagina, Lactobacillus is responsible for maintaining the acidic pH of your vagina, which allows good bacteria to thrive but kills bad bacteria before they can multiply and cause infection2

Without enough Lactobacillus, your vaginal pH can become too high, making you more prone to infections like BV, which include symptoms like

  • Increased vaginal discharge
  • Discharge that’s thin, gray-ish, and often has a “fishy” smell
  • Itchiness
  • Burning during urination or intercourse3

While BV is not considered a sexually transmitted infection or STI, sexual activity, particularly unprotected sex and/or sex with multiple partners, can increase your likelihood of infection. As you’ll see, too, chronic or untreated BV can also have an impact on your reproductive health and even your pregnancy outcomes.

Diagnosis and Treatment of BV

An image with the title ‘How does BV get diagnosed & treated?’ shows a stethoscope and pills. It explains that BV diagnosis typically involves a pelvic exam and testing a sample of vaginal fluid for bacterial overgrowth. Treatment usually includes antibiotics like metronidazole or clindamycin, along with probiotics to replenish the vaginal microbiome

You know those symptoms we just mentioned? They actually aren’t even noticed in a majority of BV cases. In fact, most people with BV don’t even know they have it. But these asymptomatic infections can still lead to health consequences down the road, which is why it’s so important to maintain regular appointments with your healthcare provider so they can screen you for infections, even ones you don’t know you have! And if you are experiencing symptoms of BV, definitely make a call to your doctor to be seen ASAP. 

To confirm your diagnosis, your doctor will typically perform a pelvic exam and test a sample of vaginal fluid to look for the presence of bacterial overgrowth. If they do determine you have BV, they will likely prescribe antibiotics like metronidazole or clindamycin. 

While antibiotics are safe, they are not without side effects, the biggest one being that they can further deplete the levels of Lactobacillus within your vagina, leaving you even more prone to secondary infections like yeast infections following treatment. To help prevent this, try taking antibiotics in conjunction with a daily probiotic like Happy V’s Prebiotic + Probiotic. It’s doctor-formulated to include only clinically proven strains of Lactobacillus, so you can make sure you are replenishing your vaginal microbiome with the healthy bacteria it needs. 

BV and Its Impact on Fertility

An image with the title ‘How can BV impact fertility?’ shows an illustration of a sperm approaching an egg. It explains that BV can impact fertility in several ways: inflammation caused by BV can interfere with sperm function and motility, BV can alter cervical mucus making it less conducive to sperm transport, and untreated BV can lead to pelvic inflammatory disease (PID), which can damage the fallopian tubes and lead to infertility.

Even though BV is super common and easily treated, that doesn’t mean it shouldn’t be taken seriously. Though more research still needs to be done to understand the exact link between BV and infertility, there is a link between the two. 

As for why it happens, science currently has a few theories. Some have proposed that the inflammation caused by BV can interfere with sperm function and motility, which can prevent fetilization, while others have proposed that BV can alter the cervical mucus, making it less conducive to sperm transport. Untreated BV can also lead to pelvic inflammatory disease (PID), which can damage the fallopian tubes, leading to infertility.

You might be asking yourself, “Well, how long does it take for BV to cause infertility?” And the answer is that we really don’t know, but when it comes to your reproductive health, you really don’t want to try to “run out the clock.” As with any infection, the sooner you treat it, the better!

And if you are currently struggling with infertility, reach out to your OB-GYN or healthcare provider for their help targeting a cause and finding a solution.

The Connections Between BV, Pregnancy, and Miscarriage

An image with the title ‘Having BV while pregnant’ shows a positive pregnancy test. It explains that untreated BV during pregnancy is very serious and associated with several risks, including increased risk of preterm birth and low birth weight, higher likelihood of postpartum endometritis or uterine lining infection, and possible transmission of BV to the newborn during delivery, which can cause health complications for the baby

If you are currently pregnant, you may not be all that worried about how or if BV can prevent pregnancy, but know that untreated BV during pregnancy is considered very serious and has been associated with all kinds of risks, including:

  • Increased risk of preterm birth and low birth weight
  • Higher likelihood of postpartum endometritis or an infection of the uterine lining
  • Possible transmission of BV to the newborn during delivery, which can cause health complications in your baby 

And while no pregnant person wants to hear the word “miscarriage,” it’s important to know that though more research is needed to establish a definitive causal relationship, there is a potential correlation between BV and miscarriage. 
This is why it’s so important to attend all your prenatal appointments, even the early ones when your baby is barely the size of a pea. During these appointments, your doctor will screen you for infections like BV so you can treat them before they lead to bad outcomes. You should also call your doctor between appointments if you ever experience bleeding or cramping.

Good Practices for Vaginal Health

  • Practicing safe sex
  • Cleaning sex toys properly after every use
  • Attending regular appointments with your gynecologist or other healthcare provider

Pregnant individuals or those trying to conceive should discuss prevention strategies, including good vaginal hygiene and daily probiotics, with their doctor
