Why do males have more blood than females?

Answer 1

Well, friend, it's not about having more blood, it's about how our bodies distribute it. Men tend to have larger bodies with more muscle mass, which requires more blood to deliver oxygen and nutrients. But remember, both men and women are unique and wonderful just the way they are, with the perfect amount of blood to keep them healthy and strong.

Answer 2

Males generally have more blood than females because they tend to have larger overall body sizes and higher muscle mass, which require more blood to transport oxygen and nutrients efficiently. Additionally, testosterone, a hormone found in higher levels in males, stimulates red blood cell production.

Answer 3

Because a hormone testosterone secreted only in males is also responsible for stimulation of hormone erythropoetin secreted from kidneys. Erythropoetin is responsible for synthesis of rbcs. So males have higher hematocrit than that of females.

Answer 4

this is due to 2 reasons-

1-females have a hormone estrogen-which has an inhibitory effect on erythropoetin-a hormone essential for erythropoeisis.

2- in males,the testosterone has an accelerating effect on erythropoetin..thereby increasing the rbc count slightly.

Answer 5

It has been shown that testosterone affects the secretion of erythropoietin (EPO) by the kidney. EPO is responsible for the formation of red blood cells. Higher testosterone in males means more red blood cell formation and hence a higher hematocrit.

Answer 6

due to testosterone hormone which stimulate the production of erythropoietin which in larger amounts increases RBC production.

Answer 7

Males are generally bigger than females, and with a bigger percentage of muscle, so male bodies can hold more blood on account of being bigger.

Answer 8

a man have too much of energy and strength but his heart is less stronger while we are comparing with woman, so they have higher count.

Answer 9

The most likely reason that male RBC counts are higher than female RBC counts is menstruation. Women of childbearing age lose a portion of their RBCs monthly.

Answer 10

It is because a woman menstruates.  A normal haemoglobin count for women is about 12 to 14, whereas the normal count for a man is from 14 to 16.
