Europe's risky TRT boom: How influencers push unneeded testosterone therapy on men

A growing trend of testosterone replacement therapy (TRT) is spreading across Europe, driven by social media and online influencers. Posts encouraging men to check their hormone levels and seek treatment have surged, despite warnings from medical experts about serious health risks.

The push for TRT began in English-speaking countries before reaching Europe. In the US, prescriptions rose by 25-30% from 2021 to 2025, according to CDC data and studies in the Journal of Urology. The UK saw a 15-20% increase, with NHS statistics showing patient numbers climbing from 45,000 to 55,000 in the same period.

Influencers and figures from the 'manosphere'—such as Andrew Tate and Robert Kennedy Jr.—have promoted TRT as a cure for fatigue, irritability, and low libido. However, Swiss fitness experts warn that most young men do not actually need the therapy. Without proper medical oversight, TRT can cause blood clots, pulmonary embolisms, bone fractures, and severe fertility issues.

At-home testosterone tests are widely available but often unreliable. Accurate measurement requires complex, expensive lab work and professional analysis. In Switzerland, TRT is only prescribed for medical reasons and is not covered by basic health insurance, costing users between 100 and 200 Swiss francs per month.

The trend continues to grow despite clear risks and high costs. Medical professionals stress that TRT should only be used under strict supervision. For most men, the therapy is unnecessary and potentially dangerous.
