Males have a higher hematocrit, since they have a greater capacity to carry oxygen in order to supply the greater muscle mass of their bodies.
Why is hemoglobin higher in males than females?
The sex difference in mean venous haemoglobin levels and red cell mass is generally considered to be caused by a direct stimulatory effect of androgen in men in the bone marrow in association with erythropoietin, a stimulatory effect of androgen on erythropoietin production in the kidney, and an inhibitory effect of …
Is the expected hematocrit amount in females higher or lower than in males?

Why do females have less hemoglobin than males?
… Starting from early adolescence, and persisting throughout adulthood, women have lower haemoglobin concentrations than men of similar age, which is probably because of the effect of sex hormones (both oestrogen and androgens) on erythropoiesis and, to a lesser extent, to menstruation.
