What is the typical normal hemoglobin range for adult men?

• A. 11.0-14.0 g/dL
• B. 13.8-17.2 g/dL
• C. 12.0-16.0 g/dL
• D. 15.0-18.0 g/dL

Answer: (B)

Hemoglobin reflects the blood’s oxygen-carrying capacity and differs by sex because hormones influence red blood cell production. For healthy adult men, a common reference range is about 13.8 to 17.2 g/dL. This higher range compared with women reflects testosterone’s role in erythropoiesis and absence of menstruation. Values below this range can indicate anemia, while values above may point to polycythemia, dehydration, or high-altitude effects. Labs can vary slightly, but 13.8–17.2 g/dL is a standard benchmark for adult men.
