What is Testosterone? Your Complete Guide
Testosterone is the primary male sex hormone, but women need it too in smaller amounts. It plays a key role in muscle mass, bone density, fat distribution, red blood cell production, and sex drive in both genders.
💡Simply Explained
Testosterone is like a construction foreman in your body. In boys, it builds muscles, deepens the voice, and helps grow taller. In girls, a tiny amount is needed too, but too much can cause unwanted changes like extra hair growth.

🩺When to See a Doctor
High Testosterone
In women, if testosterone is high with irregular periods, acne, or excess hair, see a gynaecologist for PCOS evaluation. In men, very high levels without steroid use warrant urgent investigation for tumours.
Low Testosterone
In men, if testosterone is below 200 ng/dL with symptoms like persistent fatigue, erectile dysfunction, or depression, see an endocrinologist within 2 weeks. Confirm with a morning blood test (levels peak in the morning).
🎯Did You Know?
Your testosterone level is highest in the morning — which is why blood tests for testosterone are always done before 10 AM for the most accurate result!
