Private clinics are promoting "testosterone optimisation" as a lifestyle fix for general symptoms like fatigue and weight gain, moving beyond its medical use for confirmed testosterone deficiency.
These services often use potentially unreliable finger-prick tests or single, non-fasting blood samples, which can lead to inaccurate diagnoses due to the natural fluctuation of testosterone levels.
While testosterone therapy is beneficial for men with medically confirmed hypogonadism, starting treatment when hormone levels are already normal offers little advantage and can expose people to unnecessary risks.
Inappropriate or unsupervised testosterone therapy can lead to serious side effects, including infertility, an increased risk of atrial fibrillation, and blood clots.
Experts say that testosterone is a prescription-only drug requiring careful diagnosis, regular monitoring, and specialist supervision.
