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.
Women have estrogen! It is a natural inhibitor of erythropoitin (a hormone secreted by the kidneys to erythropoiesis in the bone marrow), on the other hand, testosterone is an activator.

What is the difference between tall and long women's jeans?
Tall is for long waisted people with long legs, and long is for people who have long legs with regular waist!
Which type of graph would best show the number of men and the number women who prefer each flavor of ice cream?
Many different types of graphs could be used to represent this data: bar graphs, pie charts, line graphs etc. These are all suitable as long as there is a way to distinguish the different flavours of ice cream and also the difference between the men and women. This would probably be most easily shown by different colours for each men and women.
Assuming that the heights of college women are normally distributed with mean 65 inches and standard deviation 2.5 inches what percentage of women are between 62.5 inches and 67.5 inches?

Why do women tends to reach an higher BAC level than men?
Less of an enzyme that helps metabolize alcohol and a higher proportion of fat, which concentrates alcohol in the bloodstream.
What percentage of males wear the average shoe size?
American women, on the average, wear a size 8 wide shoe (American men: size 10.5). Approximately 68 % of American women wear shoes between the sizes of 6.5 and 9.5.
What is the difference between men and women having hematocrit?
Hematocrit levels refer to the percentage of red blood cells in the blood. Generally, men tend to have higher hematocrit levels compared to women due to hormonal differences. Menstruation and pregnancy can also impact women's hematocrit levels.
Why is there a difference in the hemoglobin levels of men women and children?
In their recent Blood correspondence, Murphy et al. postulate that the reason that men and woman have different red cell masses despite similar erythropoietin levels is due to physiologic modulation of the Fahraeus-Lindqvist effect by age, gender and red cell count 1. This hypothesis is based on the authors' observation that the difference between the venous and finger capillary hemoglobin concentrations was inversely proportional to the capillary hemoglobin level and parallel for both sexes. However, the mechanism for preferentially improved modulation of tissue oxygen delivery in women on this basis remains to be explained, particularly since the differences between the venous and finger capillary hemoglobin concentrations in men and women disappear with age even though erythropoietin production does not change with age 2. I would assert to the contrary that the explanation for differences in the red cell mass between men and women lies elsewhere and that the Fahraeus-Lindqvist effect is unlikely to be involved. First, Murphy et al. conflate the venous-capillary hemoglobin concentration difference with the so-called f-cell ratio, which is calculated by dividing the total body venous hematocrit, derived from direct measurement of the red cell mass and plasma volume, by the peripheral venous hematocrit. Importantly, unlike the authors' observed differences between the venous and capillary hemoglobin concentrations, the f-cell ratio is independent of the actual venous hematocrit and gender. Second, it is also highly unlikely that even a peripheral capillary hematocrit could serve as a surrogate for the directly measured total body hematocrit because of the wide variation in the hematocrit in various body tissues 3. Third, the hemoglobin level is a measure of something entirely different than the hematocrit and cannot be used as a substitute as the authors infer. Fourth, it is also formally possible that the authors' age-related data simply represent a regression towards the mean because as men age their hemoglobin level falls, while the female hemoglobin level does not change appreciably 4.Thus, contrary to the authors' data, the difference between the venous and capillary hemoglobin concentrations in men should have risen with age, not fallen, and the difference for the women should have remained constant unless anemia ensued. But by far the most important explanation for the difference in the hemoglobin level between normal men and women despite similar serum erythropoietin levels, is male androgen production, which the authors reject. However, when men were chemically castrated, their serum erythropoietin levels remained unchanged but their hemoglobin levels fell and when testosterone production was restored, the hemoglobin level recovered without a change in the serum erythropoietin level 5. As a corollary, when women were given testosterone, their hemoglobin levels increased. Thus, the difference between men and women with respect to hemoglobin and serum erythropoietin levels can be simply explained on a hormonal basis without having to invoke changes in tissue capillary blood flow, particularly when there is no evidence that peripheral capillary blood flow recapitulates that in the kidney where the bulk of erythropoietin is produced in the adult...
Why is the hematocrit decreased in pregnant women?
Hematocrit is the proportion of blood volume that is occupied by red blood cells. For man it is normally about 46%, for women 38%. If a pregnant woman has an abnormally low volume of red blood cells, this may need further medical investigation and attention, as it may indicate internal bleeding or hemorrhage.
What is a normal hematocrit level for women?
IT'S BEST TO keep it around 15 I also know that there is DIFFERENT ranges for example males &and ; females I ONLY know this because í am GOING TO hematologist for high. Hemoglobin counts Mine is over 20 , hope this helps i am also involved with hematologist & oncology doctors. IF Its TO high that means BLOOD Is TO THINK. They TAKE a pint and turismo it out this called venting . So this is what im GOING THRU . IF you had BLOOD test it will tell what ranges aré aré on copa OF your test ask your doctors for copy
What is the difference between muscle fibers of men and women?
no difference
What is the normal range of hematocrit for women?
The normal range of hematocrit for women is typically between 36% and 46%. Hematocrit is a measure of the percentage of red blood cells in the blood, and values outside of this range may indicate anemia or other health conditions.
