This is exactly why reference ranges matter. At Hertility, we test more women for testosterone in a single day than the entire dataset those ranges were originally based on. That scale transforms accuracy. It means our ranges reflect real women, real variability, and real patterns across age, ethnicity, symptoms, and cycles. When you anchor diagnostics in up-to-date, high-volume data, you catch what the traditional system misses. This is the difference between a system built on convenience and a system built on evidence. And it’s why our testing is able to diagnose eighteen conditions with precision, rather than dismiss them as “normal.”

If I hadn’t had my testosterone tested, I know I’d still be hiding in my cupboard crying it was one of the biggest turning points in understanding what was actually happening with my hormones. And because of Hertility’s testing, my 19-year-old daughter now has answers too, with symptoms and levels that are completely the opposite of mine. These tests have given both of us the insight to understand our bodies and actually find solutions. Thank you for continuing to speak up and push this work forward.

Well said, Dr Helen O'Neill. When you build diagnostics on outdated numbers, you inevitably miss what’s happening in real women’s bodies. When you build them on over half a million data points, you see the patterns clearly, and you stop telling women their symptoms are “normal.”

Completely agree! Hormone research has been based for too long on male datasets. We need to build more robust and stratified datasets to ensure better diagnostic outcomes. Thanks for leading this critically important work! 🙏

Love this. We had a related discussion in one of our The Pad Project ambassadors' meetings.
