-I know! I like to think about which one's my favorite.

At this very moment, there are trillions of microbes in and on your body. These bacteria, fungi,

viruses and more are a part of our bodies from the moment we're born, and we need

them. The bacteria in our gut help us digest our

food. The bacteria in our mouth and nose help us fight off infections.

Almost every part of your body has its own unique microbiome, or community of microorganisms,

and that includes...the vagina. And that's what I'm studying as a graduate

student right now! Someone should really count the

number of times we say 'vagina' in this video because it's gonna be...a lot.

-I think one of the biggest misconceptions

about the vaginal microbiome is that it's bad.

A lot of people immediately will think that microbes are not helpful to us, when in fact,

the vaginal microbiome is incredibly important for protecting us from invading microbes that

are bad. -There's an incredibly diverse microbial

party in there, and the party goers who take up the most space are a kind of bacteria called

lactobacilli. There are a bunch of different species in

this group, but they all have a very important job—taking up space and keeping the place

acidic. These lactobacilli are producing lactic acid

as they live their little lives, making your vagina have a pretty low pH.

This acidity is a really GOOD thing because it  keeps the healthy bacteria happy, and it makes it

harder for bad bacteria to take over. This is also actually why you may notice stains

or bleached areas on your underwear even after washing them—

That natural acidity of your vaginal discharge is  bleaching the pigment out of the fabric, and that's

totally normal and fine. I promise you're not weird.

In fact, this might explode your brain, but the vagina's healthy acidity has been shown

to decrease your risk of catching certain STIs, even lowering the likelihood of HIV

transmission. Although—using a barrier like a condom or

a dental dam is still absolutely necessary if you want to minimize your STI risk as much

So maintaining that healthy community of microbes

and that acidic environment is really important.

-For instance, it's associated with things

like bacterial vaginosis, which affects 10% of women in the U.S. every single year recurrently.

-If you've ever had BV, you know the struggle. Normal vaginal discharge is a combination

of cells, fun stuff your microbes are producing, the microbes themselves, and cervical mucus,

and it will vary in texture, color, and amount throughout your cycle.

Usually, discharge is clear or white, and doesn't have a bad smell. But if that microbiome

gets upset, like if something makes it more difficult for your lactobacilli to thrive...then

other species of bacteria will start to move in and   take over. Your discharge may change color, and

start to smell different, and this...is bacterial vaginosis.

It's an imbalance of the natural bacteria that are always there in your vagina,

If you've experienced this, you're not   alone because it's the most

common vaginal issue for those of us under 45.

Something similar is happening when you get a yeast infection. If your natural ecosystem

of protective bacteria has been disturbed, the yeast that naturally live in your vagina

then decide 'hey, now's my moment, let's multiply'.

The most frustrating thing is that if you take a medication for one of these problems,

like antibiotics to treat the BV, that same medication increases your chance of developing

another imbalance-driven issue, like a yeast infection.

It's like, can we catch a break? We have got to find other options than just

Actually, pro-tip, maybe you can ask  your doctor a for probiotic

along with traditional antibiotic treatment for BV.

There's also some research that using an antifungal WITH an antibiotic at the treatment

stage can help prevent this odious self-reinforcing cycle...but we still need to find better solutions.

It's truly exhausting, because SO MANY things can upset your microbes: taking antibiotics,

being pregnant, having sex, getting your period, using menstrual products, being on birth control...Like

there's so much admin that comes with a vagina!

But if there is one thing you take away from this video, please let it be this: you don't

need to wash out your vagina. I know the world might have made you feel

like you are bad or dirty for producing discharge or for smelling how you smell but if you do

something like douche, you are literally washing away all the good microbes that keep you safe

and healthy. You never have to wash out your vagina. It

cleans itself. And I know I get really worked up about this

stuff, but that's because this microbiome business has way bigger impacts than just

stuff like yeast infections, although they do suck.

-The vaginal microbiome is also implicated in secondary conditions. These include things

like preterm birth, STI acquisition, and even fertility.

-Yeah. That disruption of the natural vaginal microbiome, like we see with a condition like

BV, may increase your risk of developing pelvic inflammatory disease, a condition that can

lead to infertility if left untreated. Microbiome imbalance can increase your risk

of getting HPV...and that's a big deal, because some types of HPV can lead to cancer.

BV during pregnancy is associated with higher risk of premature birth, which poses all kinds

of risks to both birthing person and baby.  We need a better understanding of these microbial

dynamics so we can stop this from happening… this is actually what I'm doing my master's

And all of that doesn't even BEGIN to get

into stuff like urinary tract infections, which 50-60% of women will experience in their

lifetime. The vaginal and vulval microbiome definitely

affect conditions like UTIs, which also have long-term health implications, and don't

Now, at this point, like me, you may be really frustrated

by the lack of deep understanding and effective solutions we have for issues like this, but

that is changing. And this is where  companies like Hana's come in.

-We founded Juno Bio for two reasons. One is

that we believe that we needed to close the gender health gap as quickly as we could,

and that this was one of the best ways of decoding the vaginal microbiome. The second

reason is that to really decode the vaginal microbiome, we need data at scale and traditional

academic studies and the way that they're funded and run, just don't provide that scale.

Through the Juno study, we've built one of the world's richest and most representative

-Because yes—we do see differences in microbiome

makeup across ethnicities and geographic areas, across different kinds of diets, and between

vaginas and neovaginas— or vaginas that have been surgically constructed. ​
