Erm? I have no idea, considering females live longer on average.

Men have a greater volume of blood flowing through their vascular system on average because they are larger than women.  However menstrual blood is the lining of the uterus that builds up over the course of a woman's monthly cycle and is not really comparable.  Besides, the amount of blood we lose each month is pretty minimal even though it seems like a lot.

Here's a study from something called "Acta Physiol Hung" at PubMed. Short answer: Women tend to have slightly lower resting heartrates. A search on "gender pulse rate" at http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed will bring up tons of results. I hope this isn't too late...

Yes, testosterone promotes the production of hemoglobin.  It also promotes the formation of other characteristics - such as increased muscle mass.  Since females don't make as much testosterone, they have a lower muscle mass.\nMuscles use a lot of energy, so they have to make a lot of energy.  In order to do this, they need O2 and lots of it.  Hemoglobin's function is to bind O2 in the lungs, and release it in the tissues (muscles, etc. . .). \nSince men have a higher muscle mass, their muscles need more O2, so they need more hemoglobin (and therefore red blood cells) to carry that O2.\n\nHematocrit is just a quanitation of the amount of hemoglobin in a person's blood.

That is not a valid question. However, on an average, and in general, Males tend to have better "reflexes".\n\nBut there are many women out there who are better then most males!

It's not the size of the ship... it's the motion of the ocean!  JK  I just read in a magazine (Seed) that the size of your genitalia is inversely related to the IQ of the individual.  In other words... big boy = little brain.

It's all speculation, but in general, larger animals have deeper voices. Male humans are about 20% bigger than females, on average.

There are more living women but more babies are born male. Nature's way to keep the balance. Men tend to die young.. from stupid stunts and war.

Men give off more heat than women especially if they are more muscular and burn more calories via thermogenesis.  Most men I know in fact complain of the converse-- that sometimes their female companion's skin will feel cold.  My wife and i just snuggle up more, to average out the difference!  Have fun.

In males about 60% of the body mass is water. This value is about 55% in women due to a higher proportion of body fat. This is the total body water.\n\nOf this water, two-thirds of it is in the cells, and is called intracellular water. The other third is extracellular water.\n\nThe extracellular water is made up of blood plasma, which is one-fifth of extracellular water, and extracellular fluid constitutes the other four-fifths.

Men typically have more muscle mass than females.  These muscles consume a lot of oxygen, which is carried by red blood cells.  More oxygen requirements = more red blood cells.

I think there may be slightly more females in YA than males, about the same as in the world itself.  It depends on the category - seems to be more males in some categories, more females in others.
