IS THERE ANY DIFFERENCE IN THE HAEMOGLOBIN LEVELS FOR MEN AND WOMEN?IF YES,HOW WOULD THE DIFFERENCE BE EXPLAINED?

Expert Answer:

For men, normal haemoglobin levels range from 13.8 to 17.2 g/dL 

For women, the normal range is from 12.1 to 15.1 g/dL

Testosterone influences erythropoiesis during male puberty. Hemoglobin levels are similar in prepubertal boys and girls but increase in boys after age 13 years, mirroring changes in testosterone concentrations. Testosterone contributes to the 1- to 2-g/dL difference in hemoglobin concentration between adult men and women.

(Also females go through menstruation, pregnancy, childbirth, breast feeding, all of which lowers their hemoglobin levels.)
