red blood cell measurements

this is probably a very elementry question but here goes:

is the reason for the differences in male and female red blood cell measurements such as Hb concentration and packed cell volume simply because males have a higher erythrocyte count? or is it because they have more blood? or is it something else entirely?!

cheers

testosterone also has a stimulatory effect on erythrocyte production.
