Fainting is a malfunction of the brain - a shutdown response - caused by a change in blood pressure linked in with the sympathetic nervous system. This is also called the 'fight or flight' response, the change in physiology caused by an environmental stress.
When you see something which creates some sort of sympathy in your body with somebody in pain or discomfort (even the sight of blood can trigger this), your body releases hormones which restrict blood to the digestive system, accelerate the heart and breathing and sends blood to the muscles. Other responses could include increasing blood flow to the skin (blushing) or the reverse, restricting blood flow to the extremities and limiting it to the core (why some people grow pale).
In the days when ladies wore corsets, the squeezing of the abdomen increased blood pressure, making it very easy for women to faint under the slightest duress. Otherwise there is no reason why women should faint more than men.
