Why track night-time erections?

Your nightly “maintenance mode”

Every healthy man has 3–5 spontaneous erections while asleep. These cycles flush oxygen-rich blood through the tissue, keeping everything healthy, responsive, and ready for action. 

A built-in men’s health barometer

Shifts in night time erections often mirror deeper changes in your body—cardiovascular fitness, testosterone levels, and overall erection quality. Track them and you’re monitoring three pillars of men’s health with one simple metric.

Discover your AndroAge™

Adam converts your overnight data into AndroAge™—a real-time score of how youthful your erectile system is. Watch it improve as you optimise habits, and treat any uptick as an early prompt to act.

Tracking is effortless

Step 1

Pop it on before going to bed, it’s designed for comfort for a great sleep.

Step 2

Wake up, turn your phone back on and sync the results to the Adam Health app

Step 3

Review the results, analyse trends, gain actionable insights and feel informed.

What are the experts saying?

    - Dr Ranjith Ramasamy, Consultant Urological Surgeon

  • “Tracking night-time erections is one of the single best indicators of a man’s overall health and wellbeing.”

    - Professor Amr Raheem, Consultant Andrologist & Professor of Men’s Health

  • “Healthy erections are built while you sleep. The Adam Sensor proves it, showing which habits boost or blunt night time erections and long-term function. Its data drives the research and protocols I share with my men’s-health communities, because data beats marketing.”

    - Jordan Tsanev, Citizen Scientist & Men’s-Health Communities Leader

  • “Night-time erections are a little-known yet crucial biomarker of sexual function, as well as cardiovascular, hormonal, and lifestyle health. The Adam Sensor, a revolutionary technology once confined to sleep labs, now puts this insight in any man’s hands.”

    - Dr Ben Davis, Men's Health Doctor and Clinical Sexologist

  • AndroAge™ provides a unique insight into your erection, vascular and hormone health through an estimated score. It measures the total duration and frequency of your nightly erections and compares it to reference data from an independent, peer-reviewed clinical study of healthy men aged 20-75+. The result is a personalised estimate, showing you at a glance if your nocturnal patterns reflect a younger or older physiological age than average.

  • Any orders get sent out in discrete packaging via recorded delivery and include a two year warranty.
