The Basics: What Does Testosterone Do?


Testosterone is a hormone produced primarily in the testicles (for men) and in smaller amounts by the ovaries (for women). It plays a key role in:


• Building and maintaining muscle mass

• Supporting bone density

• Fueling libido and reproductive health

• Maintaining red blood cell production


Beyond the physical, testosterone is also linked to mood, energy, and overall quality of life  .


Misconceptions: Busting the Myths


1. Testosterone is only about sex and muscle.

• While testosterone does contribute to these areas, it’s also critical for cognitive function and emotional stability. Low testosterone (often called “Low T”) can lead to fatigue, depression, and mental fog .


2. More testosterone is always better.

• Excess testosterone can cause side effects like aggression, acne, and even health risks such as blood clots or polycythemia (a condition where the blood becomes too thick) .


3. Testosterone therapy is unsafe.

• Recent studies, like the TRAVERSE trial, confirm that testosterone replacement therapy (TRT) is safe for most men when prescribed appropriately. In fact, it does not increase major cardiovascular risks, debunking older fears .


What Science Knows Today


Levels Matter: Normal testosterone levels vary widely. For men, the typical range is 300–1,000 ng/dL. But even within that range, symptoms can appear if levels drop too low .

Causes of Low T: Age is the biggest factor, with levels naturally declining by about 1% each year after age 30. Other causes include stress, poor diet, lack of exercise, and certain medical conditions like obesity or diabetes .

Treatment Benefits: TRT can help restore energy, improve mood, increase muscle mass, and even enhance sexual function. However, it’s not one-size-fits-all. Careful monitoring is essential to avoid side effects  .


Key Takeaway


Testosterone is a powerhouse hormone that keeps your body and mind running smoothly. While it’s no cure-all, understanding its role and addressing deficiencies can lead to a healthier, more vibrant life.
