Description
This video describes a study that establishes age-stratified reference ranges for directly measured free testosterone (mFT) using the gold standard method of equilibrium dialysis followed by liquid chromatography tandem-mass spectrometry. By analyzing serum samples from over 1,200 healthy, community-dwelling men, the researchers observed that free testosterone levels significantly decline as men age, dropping by an average of 4.5 pmol/L annually. The findings also highlight that a higher Body Mass Index (BMI) is associated with a notable decrease in available testosterone, independent of aging. While a reference range of 184-749 pmol/L was identified for healthy men aged 18 to 39, the authors provide detailed benchmarks for every decade of life. Ultimately, this research offers a more precise diagnostic framework for evaluating male hormone health and managing conditions like hypogonadism. #freetestosterone
