Although estradiol production is typically considered a female concern, men also need to maintain healthy levels of this hormone for optimal health. Since men lack ovaries (where most estradiol is produced in women), estradiol in men is created by a process that uses an enzyme called aromatase (<a href="https://www.sciencedirect.com/science/article/pii/S0039128X11003175?via%3Dihub" target="_blank">1</a>) in testicles, liver and fat cells.</p><p></p><p>Aromatase converts a very small portion of testosterone levels into estradiol, and health problems can arise when aromatase levels are too high or too low (<a href="https://www.sciencedirect.com/science/article/pii/S0039128X11003175?via%3Dihub" target="_blank">1</a>).</p><p></p><h2>When aromatase is unbalanced, estradiol becomes an issue</h2><p></p><p>As men age, they can experience excess aromatase activity, raising estradiol levels and reducing testosterone to unhealthy levels.
