Influencers linked to the online “manosphere” are persuading healthy young men that normal tiredness, stress or changes in libido are signs of low testosterone, according to a study in Social Science and Medicine.
Researchers analysed popular posts on TikTok and Instagram, finding that routine testosterone testing is being marketed as essential to masculinity, despite being medically unnecessary for most young men.
The lead author from the University of Copenhagen said influencers often frame normal experiences as medical problems, driving demand for tests and supplements. Experts warn this “medicalisation of masculinity” carries risks, including unnecessary treatment, side effects and missed underlying health issues.
