One Device. One Hypothesis. An Invitation to Collaborate.

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 discover a potentially cost-effective intervention for reducing preterm birth — a finding that now drives the company's research mission.
How Circunaro Came to Be
Circunaro began when the founding team identified the lack of non-invasive solutions for men seeking relief from genital hypersensitivity and premature ejaculation caused by hypersensitivity — the device's original medical indication. During years of commercial operation, the team worked closely with researchers across Europe, exploring the device's potential beyond that indication. The team itself first identified the potential connection to bacterial vaginosis and urinary tract infections in female partners. A pivotal moment came through collaboration with IDIAP Jordi Gol, Spain's primary care research coordination institute, where Dr. Gemma Falguera broadened the focus further — identifying preterm birth as the most significant downstream maternal health outcome to investigate. This insight completed a strategic pivot: from a registered medical device to a research platform exploring how male genital microbiome modulation could contribute to protecting maternal health.
Why We Do This
To generate evidence for affordable, non-antibiotic approaches to protecting maternal health through male partner hygiene.
Preterm birth kills more than one million newborns every year. The science increasingly points to the male genital microbiome as a modifiable contributor. We believe a simple, mechanical intervention could make a difference — but that belief requires rigorous testing. We are not here to sell a product. We are here to find the researchers who can test whether this hypothesis holds.
