Testosterone is the primary male sex hormone, responsible for regulating many bodily functions, including sexual drive, muscle mass, bone density, mood, and energy levels. As men age, it’s natural for testosterone levels to decline gradually. However, for some men, this decline is more significant and can lead to a condition known as low testosterone, or “Low T.” https://sccplano.com/blogs/low-testosterone-sexual-health-clinic-when-to-seek-help/
