Low testosterone, often referred to as “Low T” or hypogonadism, is a medical condition in which the body doesn’t produce enough testosterone, the hormone for maintaining male physical and mental health.

Clinically low testosterone refers to a specific range of testosterone levels in the blood, which is considered below the normal threshold for a given age.⁸

Testosterone supplements are nutritional aids designed to support testosterone levels, whereas TRT is a medically supervised treatment for men diagnosed with low testosterone. TRT involves administering testosterone to restore healthy levels of the hormone and alleviate the symptoms of hypogonadism.³

TRT can be administered in several forms, including injections, gels, or tablets. The method of administration will depend on the individual's health profile and lifestyle, as well as the preference and guidance of the healthcare provider. Regular monitoring by a healthcare professional is essential to adjust dosages and ensure the therapy’s effectiveness while minimising side effects.³

If you're experiencing symptoms such as fatigue, decreased libido, erectile dysfunction, or other physical and emotional changes, you might have low testosterone.⁸

A blood test is the only reliable way to determine your testosterone levels. If your levels are clinically low, your doctor might recommend TRT as a treatment option to restore normal levels and improve your health and wellbeing.

The effects of TRT can be felt within just a few weeks, but full benefits may take several months to manifest. The timeline can vary depending on the person's baseline testosterone levels, the form of therapy chosen, and their overall health. Regular follow-ups with a healthcare provider is important to monitor the therapy's effectiveness and make any necessary adjustments.⁷

The cost of TRT will vary depending on the type of TRT you're prescribed. Prices can vary between £90 and £150, and these costs will take into account your consultation and ongoing monitoring blood tests.

Low testosterone is linked to ED so if this is the case for you then restoring your testosterone levels to the normal range may help to alleviate the symptoms of ED.^3,8 However, if ED persists, additional treatments specifically targeting erectile dysfunction may be needed. Always consult with a healthcare professional to determine the most appropriate treatment for your situation.

Two blood tests are required to ensure an accurate diagnosis of low testosterone. The initial test provides a preliminary assessment. Since testosterone levels can naturally fluctuate due to various factors, a second blood test confirms these results.¹ This two-step process minimises the risk of false positives and provides a solid basis for any necessary treatment.

A Venous Blood Test (VBT) is a clinical blood test taken from a vein, typically from the arm. It’s carried out by a trained professional, either in a clinic or at home by a mobile phlebotomist. This test provides a highly accurate and detailed analysis, making it suitable for medical diagnosis.
