Testosterone
What It Is
Testosterone is the primary male sex hormone, essential for muscle mass, bone density, libido, and reproductive health.
Why It Matters
Testosterone levels decline with age. Symptoms of low testosterone include fatigue, mood changes, and reduced libido.
If Levels Are High
Elevated testosterone in women may indicate PCOS. In men, it is less commonly a concern unless due to external use.
If Levels Are Low
Low testosterone in men can cause fatigue, depression, reduced muscle mass, and sexual dysfunction.
Preparation
Morning sample required (before 10am). Fasting may be recommended.
How Often to Test
As clinically indicated, typically when symptoms suggest hormonal imbalance.
