The ADAM questionnaire is a 10-question yes/no screening tool for symptoms of low testosterone in men. It counts as positive if you answer yes to the sex-drive question, the erection-strength question, or any three of the other eight. It screens; it does not diagnose. Only blood tests reviewed by a provider can confirm low testosterone.

Effects of testosterone therapy arrive on different schedules. In a review of published studies, sexual interest improved from about 3 weeks and plateaued around 6 weeks, mood and quality of life began to shift in 3 to 6 weeks, body composition and strength changed over 12 to 16 weeks, erections could take up to 6 months, and some effects, such as bone, continued for years. Individual results vary.

Free testosterone can be estimated from three blood results: total testosterone, SHBG and albumin. The Vermeulen equation converts them to mol/L, accounts for testosterone bound to albumin, and solves a quadratic equation for the unbound fraction. For 500 ng/dL total testosterone, SHBG of 30 nmol/L and albumin of 4.3 g/dL, free testosterone comes out near 0.38 nmol/L, about 2.2% of the total.

Yes, low testosterone can contribute to erectile dysfunction, mainly by lowering sex drive and affecting night-time and spontaneous erections. But most ED involves blood flow, nerves, other health conditions or stress, and low testosterone is only one possible factor. A blood test and a provider evaluation separate them. Testosterone therapy helps only when low testosterone is genuinely part of the problem.

An erectile dysfunction evaluation usually includes a sexual and medical history, a short questionnaire such as the SHIM, a review of medications, a physical check that may include blood pressure and weight, and blood tests such as testosterone, blood sugar and cholesterol. Much of this can be done by telehealth, with a blood draw at a local lab, though some exams may need an in-person visit.
