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.

If your symptoms are severe or getting worse, speak to your GP or call 111.
What a blood test can check

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.

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.

FAQs

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.
