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.

✓ Verified customer“My girlfriend tried other testing companies but we never understood how or if I was contributing to her recurrent bacterial vaginosis.”
Alex
✓ Verified customer“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.”
Carlos
✓ Verified customer“Anteros helped guide me through back to back yeast infections then UTIs.”
Melisa
✓ Verified customer“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.”

The Anteros Bio kit is the first at-home genital microbiome test designed specifically for couples. It includes two swab kits — one for each partner — that analyse the vaginal and penile microbiome. Results are delivered through a personal online portal and include the Anteros Score: a snapshot of each partner's microbiome health and compatibility.
Because microbiomes are connected. During sex, microorganisms transfer between partners — meaning one partner's imbalance directly affects the other. Testing only one partner gives an incomplete picture and often explains why infections persist. Testing both reveals the interaction between your microbiomes and makes targeted treatment possible.
Yes — and this is one of the most clinically significant findings in recent research. Men can carry BV-associated bacteria on the penile skin and in the urethra without experiencing any discomfort, discharge, or other symptoms. This means male partners of women with recurring BV are often unknowing reinfection sources.
You collect a swab sample at home using the included non-invasive swab. Both partners complete their own collection privately. The samples are sent to a CLIA, CAP, and CLEP certified lab using a prepaid return label. Results are available in your secure online portal within 7–10 days of the lab receiving your samples.
No. The Anteros Bio test analyses the microbiome — the community of bacteria and fungi in the genital area — and does not test for sexually transmitted infections (STIs). It is designed to identify microbiome imbalances that contribute to recurring infections like BV, yeast infections, and UTIs. For STI testing, consult your healthcare provider.
You and your partner each get your own result portal. You can also link your results to view them together. Your report explains your microbiome in plain language. It gives you a clear starting point for your next steps. You can also share it with your healthcare provider if you want extra guidance.
Yes. You can securely share your results with your partner. And you can remove access at any time. You stay in control of your information. Always.
Frame it as a science conversation, not a blame conversation. You might say: 'I keep getting infections and I've learned that the microbiomes of couples are connected — there's a test we can both do at home to see what's happening between us.' Emphasising 'we' rather than 'you' makes it a shared health journey rather than an accusation.
Breaking taboos, exploring the science, and making intimate health part of the conversation.
