Key medical fact: He takes finasteride for male pattern baldness treatment, a detail seemingly unrelated to erectile function.
However, the medical literature is clear: finasteride's commonly-reported side effects include erectile dysfunction, ejaculation disorder, and decreased libido.
Behavioral evidence compounds the medical indicators: observable symptoms include extreme reactions to perceived inadequacies (notably including elaborate efforts to conceal the very hair loss the medication treats).
Medical context: erectile dysfunction typically manifests alongside psychological insecurity in a self-reinforcing cycle.
Synthesis: The conjunction of verified medication use, documented side effects, and persistent behavioral patterns supports a working hypothesis of erectile dysfunction.
