Why test your microbiome?

Managing symptoms. Planning for fertility. Or just want clearer answers. It all starts with knowing what's actually going on below the belt.

GET TO THE ROOT

Chronic BV, UTIs, yeast infections aren't random. Get insights to the cause, not just the flare-up.

KNOW WHAT YOU'RE SHARING

Reinfection isn't always on you. Anteros is the only place partner analysis is accessible.

GET AHEAD OF FERTILITY 

Microbiome imbalances can affect sperm health and pregnancy. Know where you stand before you start trying.

STAY AHEAD, NOT BEHIND

Whether you're just curious or proactively tracking, explore your intimate heath to catch changes early.

Healthcare was built around individuals. Relationships weren't.

Let's really get intimate. Test together, heal together.

ANTEROS

(Greek: Ἀντέρως, Antérōs)
Love, returned. In Greek mythology, Anteros represented reciprocal love, love that is returned rather than experienced in only one direction. We chose the name because we believe intimate health deserves the same reciprocity. Not just you. Not just them. Both.

Founders note

I spent almost three years cycling through recurring UTIs, tested and treated over and over, while my partner sat outside the conversation entirely. That's when it hit me: we share everything else, why not this? Healthcare still treats intimate health one person at a time. We built Anteros to treat it the way it actually works, together.

Individuals and couples trust Anteros for their intimate health journey

Anteros relieved so much strain from my intimacy and my relationship. Understanding what microbes were there I wasn’t seeing from my normal clinical visits was extremely validating. Comparing our reports was a great sanity check. The fact no one tested my partner never sat right with me. I can't wait to see how Anteros continues to support couples who are stuck in cycle of recurrence!

My girlfriend tried other testing companies but we never understood how or if I was contributing to her recurrent bacterial vaginosis. We saw we shared similar disruptive microbes in our sample and took them to our provider who helped the both of us get treated at the same time. She hasn’t had any recurrent symptoms for a few months! Every couple who may be on the fence should test with Anteros and at least verify they may not be paying a role in their partners symptoms.

Easy to use. I had no difficulty swabbing with my partner and syncing our results together made it easier to compare our results side by side. I was pleased to see we didn’t share any problematic bacteria so now we can move on and potentially start family planning.

Anteros helped guide me through back to back yeast infections then UTIs. A lot of my symptoms overlapped so there was a time when it wasn’t really clear what I was treating. My chronic pain prohibited so much from my personal life and made it hard to go through day to day. The portal was so much more simple and intuitive compared to other testing companies. I look forward for Anteros to expand their post on follow on care!

My wife is in menopause and has been struggling with recurrent symptoms over the last few years. We tried over the counter products but wanted to check I wasn’t contributing to any of the reinfections. We haven’t seen any other at home test include partners so we wanted to give it a try. The platform made it easy for us to check our results and track them over time if we needed to. We got the clarity we needed to take back to our provider. We would recommend Anteros to other couples who want to be proactive about their health or want to rule out partner transmission.
