A small team working on one open question

Manuel
Manuel Becerril is one of the founders of Circunaro. During the company's commercial years, he managed general operations and business development. He has also consulted on technology valorization at the Tech Transfer department of IMB-CNM (National Microelectronics Centre), focused on diagnostic tools for low- and middle-income countries. Passionate about science, technology, nature, and effective altruism, his work exploring new indications for the Circunaro device led him to the research on the male partner and bacterial vaginosis that now drives the company's work.
How Circunaro Came to Be
Circunaro began as a company selling a silicone ring for men with genital hypersensitivity. While working with researchers across Europe, the team came across the literature linking the male genital microbiome to bacterial vaginosis and urinary tract infections in female partners. Conversations with researchers, including at IDIAP Jordi Gol in Spain, led us to broaden the question to maternal health. We have since moved from selling the ring to supporting research and developing a new approach.
Why We Do This
To find out whether a non-antibiotic, partner-applied approach can reduce recurrence of bacterial vaginosis.
Bacterial vaginosis is common, and it often returns after treatment. A 2025 randomized trial showed that treating the male partner with antibiotics reduces recurrence. Whether something gentler and longer-lasting can do the same is an open question, and a hypothesis we have not tested. Circunaro has a commercial interest in this area. Our academic collaborations are independent: research partners keep full rights over data and publication.
