Why this panel

Erectile function depends on blood vessels, nerves, hormones and mood — and the vascular component usually fails first. This panel checks the hormonal causes and, just as importantly, the cardiovascular ones.

💡 What most people missErectile dysfunction is frequently an early warning of cardiovascular disease, not a hormone problem. The penile arteries are narrower than the coronaries, so endothelial dysfunction shows up there first — often 3 to 5 years before a cardiac event. That makes new-onset ED one of the most actionable warning signs in medicine, and treating it with a PDE5 inhibitor while ignoring the vascular picture is a genuinely missed opportunity. The most commonly overlooked hormonal cause is prolactin — a prolactinoma can present with low libido long before anything else, and it's a $9 test.

⏰ When to get it drawnMorning, 7–10am, fasted.
