How to know if a person is impotent? Are there tests?

Erectile difficulty is common, treatable, and frequently a signal about general health rather than a purely sexual problem. The vascular point matters: the arteries supplying the penis are small, so reduced blood flow often shows there before it shows anywhere else. New erectile difficulty can be an early indicator of cardiovascular disease or undiagnosed diabetes, which is why assessment should include blood pressure, blood sugar, lipids and often testosterone — not just a prescription. Other contributors: medications (particularly some antihypertensives and antidepressants), smoking, alcohol, thyroid dysfunction, sleep apnoea, and anxiety — which frequently compounds whatever started it. For conception specifically, the issue is usually achieving intercourse during the fertile window rather than sperm quality, which is typically unaffected. Where difficulty persists, options exist including timed treatment, and where needed IUI using a collected sample. Please see a urologist or andrologist. Do not use online-purchased medication — counterfeit products are widespread, and PDE5 inhibitors are dangerous with nitrates.
