Honest answer: there's no fixed number for how often men should have their blood tested. It depends on your age, your symptoms, your lifestyle and your family history. Some men choose to measure periodically to build a picture over time, others only when they have complaints.
I actually find that "no fixed number" a pleasant answer. It means you don't have to run on autopilot, but can look at what fits you together with your GP.
Why is there no fixed answer?
What's useful differs per person. Someone with complaints or a loaded family history has a different story than someone without. So your GP looks at your situation instead of a general rule.
Which factors matter?
Think of your age, any complaints, your lifestyle, your weight and what runs in your family. A previous result counts too: a value you watch move over time says more than a single reading. See blood test in your 30s for the idea of a baseline.
What is a sensible approach?
A commonly chosen approach is: measure when you have complaints or want a reference point, and discuss the result with your GP. They can help decide whether and when a follow-up is useful. See also men's health after 40.
