Low energy, low drive or other symptoms in men? Testosterone and more can be checked
Low energy, reduced motivation, a drop in sex drive, and difficulty maintaining muscle are symptoms many men put down to 'just getting older' or work stress. Sometimes that's exactly what it is — but low testosterone, thyroid problems and metabolic changes can all contribute, and each is straightforward to check with a blood test.
Testosterone monitoring looks beyond a single reading to show how much testosterone is actually available to your body, while broader men's health panels combine hormone, thyroid and metabolic markers for a fuller picture.
This page covers the common blood-testable causes and the panels that check them, so you can get a clear, clinician-reviewed answer.
Common blood-testable causes
Low testosterone
Declining testosterone can affect energy, mood, muscle and sex drive. Testosterone monitoring measures total and free testosterone, SHBG and the free androgen index.
Check with Testosterone Monitoring →Thyroid dysfunction
An underactive thyroid can cause fatigue, low mood and weight changes that overlap with low testosterone symptoms.
Check with Thyroid Profile →Stress hormone imbalance
Sustained high cortisol can suppress testosterone production and contribute to fatigue and low mood.
Check with Stress Panel →Metabolic factors
Excess weight and insulin resistance are linked to lower testosterone, forming a cycle worth checking with blood sugar markers.
Check with Diabetes Status →Panels worth considering
Testosterone Monitoring
This panel looks beyond a single total testosterone reading to show how much testosterone is actually available to your body.
SS Plus Hormonal (Male)
This panel combines a full Standard Screen Plus with an expanded male hormone profile in a single blood draw.
Thyroid Profile
Your thyroid controls your energy, weight and mood. This panel checks all four key thyroid markers — much more thorough than a standard NHS TSH-only test.
Common questions
When is the best time of day to test testosterone? +
Testosterone is highest in the morning, so a morning appointment gives the most reliable reading. Our team will confirm timing when you book.
Can this test be used to monitor testosterone replacement therapy (TRT)? +
Yes, testosterone monitoring is commonly used to check that TRT is keeping your levels in the intended range. It's a monitoring tool, not a substitute for advice from your prescriber.
What else could explain my symptoms besides testosterone? +
Thyroid problems, stress hormone imbalance and metabolic factors like insulin resistance can cause similar symptoms. Our SS Plus Hormonal (Male) panel combines general health markers with a fuller hormone profile for a broader picture.
