Testosterone: Use and Commercial Availability 

Testosterone helps in regulating various physiological processes. It plays a significant role in developing secondary sexual characteristics, including the growth of muscle mass, bone density, and body hair. In cases of low testosterone levels, a condition known as hypogonadism, Testosterone acts as hormone replacement therapy (HRT). This therapy aims to restore testosterone levels to their normal range, effectively addressing symptoms such as fatigue, decreased libido, and mood disturbances.

This medicine is available under many brand names – Androderm, Androgel, Natesto, Axiron, Striant, etc. All of them contain the active ingredient Testosterone.
