Non-specific symptoms of testosterone deficiency (TD) and lack of awareness impact diagnosis and appropriate treatment. This study aimed to characterise the awareness of key symptoms of TD in community-dwelling men and contextualise this against the reported prevalence of these symptoms.

Cross-sectional survey comprising 54 questions (including assessment of symptoms as per the qADAM questionnaire and where relevant, men’s experiences while on TD treatment). The survey was distributed through online media channels, Prolific and academic networks.

Community-dwelling men in the UK.

Associations between age, participant demographics and a ‘positive’ qADAM score were assessed using logistic regression. A positive qADAM score was defined as self-rated ‘poor’ or ‘terrible’ libido or erection strength or rating 3 of the other questionnaire domains as ‘poor’ or ‘terrible’.

Of 973 men, 49% indicated high likelihood of TD using qADAM scores—5% were formally diagnosed. Men over 50 years of age had 1.54–2.0 times higher odds of TD compared with men aged

Almost half of the responders exhibited a burden of TD-associated symptoms, but under 5% had a formal diagnosis. These findings suggest significant gaps between symptom awareness and access to treatment options.
