What I've learned is for many years, measuring total testosterone has served as the cornerstone for doctors assessing testosterone levels. However, science is shifting toward the measurement of free testosterone, as emerging research underscores its critical role in maintaining overall health.
Total testosterone levels play a vital role in diagnosing conditions such as hypogonadism and infertility, as well as in monitoring men on testosterone replacement therapy. Yet, this approach can be somewhat misleading, as approximately 98% of testosterone is bound to proteins like sex hormone-binding globulin (SHBG) or albumin. This binding obscures the true picture, making it possible to miss the vital amount of free testosterone circulating in the body.
Recent compelling studies have delved into the intricate relationship between testosterone levels and aging. The findings are striking, men with lower levels of free testosterone are not only more susceptible to memory issues but also face a significantly heightened risk of developing Alzheimer’s disease as they grow older. This highlights the importance of understanding and monitoring free testosterone levels in promoting not just hormonal health, but cognitive vitality throughout the aging process.
