Longevity Optimization with Kayla Barnes-Lentz I Became the First Woman in the World to Test Her Ovarian Age
Feb 14, 2026
She reveals being the first person to take a new ovarian age test and explains how the machine learning algorithm uses hormones, body composition, and history. She outlines plans to test interventions like hyperbaric oxygen therapy and isolation protocols. She reviews five proposed drivers of ovarian aging, from mitochondrial dysfunction to fibrosis, and practical steps to support ovarian health.

Episode notes
Algorithm Combines Real-World Data
- Timeless Biotech's test combines hormone biomarkers, body composition and reproductive history with a machine-learning model trained on 40,000 real women.
- The algorithm runs billions of computations to provide an ovarian age estimate that contextualizes individual biomarkers.
Ovarian Age Has Narrower Window
- Ovarian biological age has a much shorter effective span (~35–40 years) than whole-body lifespan, so a few years' difference is meaningful.
- Kayla interprets her minus-five result as significant given ovarian lifespan limits and her age of 35.
Master The Basics First
- Establish solid foundational habits: prioritize high-quality sleep, nutrition, exercise, social connection and stress reduction.
- These basics underpin any interventions aimed at slowing ovarian aging.
