Signs of low testosterone and how TRT can help

Low testosterone, also known as testosterone deficiency or male hypogonadism, can significantly affect a man’s physical, emotional, and mental wellbeing.

In this article, Dr David Dawson, a GP practising at The WellMan Clinic, explains the common signs of low testosterone, how it is diagnosed, and how testosterone replacement therapy (TRT) can help manage symptoms and restore hormonal balance.

What is testosterone and why is it important?

Testosterone is the primary male sex hormone, responsible for the development and maintenance of many essential functions in the body. These include muscle mass, bone density, libido, mood, red blood cell production, and cognitive function.

While testosterone levels naturally decline with age, a significant deficiency can cause a range of symptoms that interfere with daily life.

Common signs and symptoms of low testosterone

Low testosterone can present with a wide range of symptoms. While some are subtle, others may be more noticeable or disruptive.

Physical and sexual symptoms:

• Persistent fatigue or reduced energy levels.
• Decreased muscle mass or physical strength.
• Increased body fat, especially around the abdomen.
• Reduced libido (sex drive).
• Erectile dysfunction or weaker erections.
• Hair thinning or loss.
• Reduced bone density, increasing fracture risk.

Emotional and cognitive symptoms:

• Low mood, irritability, or increased anxiety.
• Reduced motivation or confidence.
• Poor concentration and memory (brain fog).
• Sleep disturbances, including difficulty falling or staying asleep.

If you are experiencing several of these symptoms, it may be appropriate to speak to a GP about further assessment.

How is low testosterone diagnosed?

Diagnosing testosterone deficiency involves both clinical assessment and blood testing. Your doctor will take a detailed medical history and ask about symptoms, general health, lifestyle, and any medications.

Preferably, a morning serum testosterone blood test, should be taken before 11am. This test measures total testosterone levels. Morning testing is preferred because testosterone follows a daily rhythm and peaks during the early hours of the day.

How can testosterone replacement therapy (TRT) help?

TRT aims to restore testosterone to healthy levels, relieving symptoms and improving quality of life.

Potential benefits of TRT include:

• Improved mood and energy.
• Increased libido and better sexual function.
• Enhanced muscle mass and reduced fat.
• Sharper focus and clearer thinking.
• Improved bone strength.
• Better sleep quality.

TRT is available in several forms, including gels and injections. The choice of treatment depends on individual preference, lifestyle, and response.

Is TRT suitable for everyone?

TRT is generally safe when prescribed and monitored by a qualified doctor. Regular monitoring is essential during treatment. This includes checking testosterone levels, blood pressure, red blood cell count (haematocrit), prostate health (PSA levels), and cardiovascular risk factors.

Low testosterone can have a significant impact on both physical and emotional wellbeing. If you’re noticing ongoing fatigue, reduced drive, or low mood, a discreet consultation with Dr Dawson via his Top Doctors profile could be the first step toward reclaiming your wellbeing.
