If you’re a man between 40 and 70 and the symptoms below feel familiar, low testosterone could be the reason. The good news: it’s measurable, and it’s treatable.
Low testosterone can quietly dim a man’s sex drive, his performance in bed, his energy and his motivation. If you recognise several of these, it’s worth having your level checked.
Not sure? Take our anonymous “Could I have low testosterone?” quiz.

Experienced doctors measure what’s called free testosterone, the amount of the hormone that is actually active in your body at a given time.
A man whose total testosterone sits in the “normal” range can still have every classic symptom of low T if his free testosterone comes up short. Free testosterone is far more indicative of your true status.
Low energy, low mood and a flat drive are often dismissed as “just ageing”. They’re frequently a hormonal problem with a real solution.
Testosterone peaks during adolescence and early adulthood, then declines, typically about 1% per year after age 30.
In older men it’s important to determine whether a low level is normal ageing or driven by a disease (hypogonadism). That distinction changes everything about how you should be treated.
Nutritional deficiencies (especially vitamin D, vitamin C, zinc and magnesium) and exposure to chemical toxins in pesticides and plastics, many of them estrogen mimickers, can suppress testosterone.
