#26 Kerli Luks: Building the First Wearable for Continuous Female Hormone Monitoring

Priit Kruus sits down with Dr. Kerli Luks, physician and founder of Muun Health, a startup developing what aims to become the world’s first wearable device for continuous female hormone monitoring. The technology seeks to provide real-time insight into ovulation, fertility, and broader reproductive health -  an area of medicine that has long remained difficult to measure continuously and objectively.Drawing on her clinical experience as ER and primary care doctor, Kerli shares how years of treating patients with hormonal and fertility challenges revealed a fundamental gap in women’s health: despite rapid advances in digital health and biosensing, reliable tools for monitoring female hormones have remained limited. This realization became the starting point for Muun Health’s ambitious mission.Together, Priit and Kerli explore the realities behind building breakthrough medical technology -  from biosensor development and physiological complexity to MDR regulation, fundraising, and the long innovation cycles typical of healthcare startups. The conversation offers an honest look at both the promise and the challenges of bringing deep-tech medical innovation from idea to clinical impact.
