Introduction

Testosterone is the primary male sex hormone responsible for muscle mass, bone strength, mood, and sexual health. Maintaining balanced testosterone levels is essential for overall well-being in men.

A testosterone test helps measure hormone levels in the blood and is commonly used to diagnose hormonal imbalances, especially low testosterone (hypogonadism).
