Like most medical terms, the concept of "erection" came to us from Latin. Translated from the ancient language, it means "to be firm." Indeed, the main sign that a normal erection has occurred is the hardness of the penis, since a flaccid and soft organ is problematically inserted into the vagina.
In order to find out what an erection is, one should turn to such a science as anatomy. In normal, unprepared terms, the penis is poured with blood when excited. Here, everything is directly connected with the cardiovascular system, since excitation, as a rule, is accompanied by an increase in the pulse, the heartbeat increases, and with it the flow of blood to the genital area increases. When answering the question of what an erection is, it should be taken into account that the blood pressure in the genital area, which is in the normal state, is insignificant, but after reaching sexual arousal it increases by more than 20 times. Tissues filled with blood begin to narrow, while squeezing the sections of the discharge veins. Thus, the penis hardens and increases in volume. Scientists have proved that a small organ with sexual arousal can increase by more than half, while the average male member, reaching a length of 18 to 20 cm, does not change very much in an erect state. This is what an erection is.
To achieve a good erection, the following factors are required. Firstly, they are strong, healthy and, most importantly, correctly functioning nerves. It has been proven that the centers of the nervous system that are responsible for sexual arousal are located in the spinal cord and brain. With the defeat of some parts of the nervous system or their incorrect operation with an erection, serious problems can arise.
Secondly, achieving a normal erection also depends on the state of the cardiovascular system. Normal functioning of the heart and blood vessels, in turn, is achieved through proper nutrition, walking in the fresh air, lack of stress and neurosis. Men should avoid overwork, junk food and overeating, as well as drinking large amounts of alcohol and nicotine. And you need to regularly visit a cardiologist to monitor the work of the cardiovascular system.
Speaking of sexual arousal, one should also find out what a constant erection, or priapism, is. Most men, having heard about a constant erection, are likely to decide that this is very good, but this is far from the case. The fact is that priapism is a dangerous disease. A constant erection, as a rule, occurs without sexual arousal, it is accompanied by a delay in blood in the tissues of the penis. Priapism is often accompanied by pain, sometimes very severe. If symptoms of this disease appear, you should immediately consult a doctor, since in the early stages, priapism is treated with medication and physiotherapy.
I hope that after reading this material of the question "Erection - what is it?" you will not arise.
