PARNTER HEALTH IS SHARED HEALTH

Traditional testing treats partners separately, overlooking the full picture of shared health. Anteros Bio changes that. Because real answers begin when both partners are seen.

SEE IF IT'S RIGHT FOR YOU

Discover the solution for individuals and couples with chronic intimate infections. Traditional testing is only half the equation. With Anteros Bio, we’re looking for both partners to test, providing insights around urinary tract infections, bacterial vaginosis, and other recurring infections sooner with more granular testing.

INVEST IN CLARITY, PRECISION AND HEALTH.

The Self-Test Kit

For too long, intimate health has meant short appointments and incomplete answers. If you’ve been cycling through recurring symptoms and temporary fixes, this is your next step forward.

The Anteros Microbiome Kit provides a deeper look into your vaginal or penile microbiome through a simple at-home swab. By identifying bacterial patterns linked to imbalance, it helps you move beyond guesswork and toward real clarity.

No waiting rooms. Just science, insight, and a clearer understanding of your body.

The Partner-Test Kit

Intimate health is shared, even if testing hasn’t been. The Couples Microbiome Kit is designed to evaluate both partners together, offering a connected view of your microbiomes and how they interact.

Recurring symptoms often reflect shared patterns. Testing both partners can reveal what individual results may miss, bringing transparency to your health as a couple.

Because your microbiomes are connected and your answers should be too.
