How does penis get hardened?

Penis is an anatomically porous organ. These pores are filled with blood with sexual stimulation, and the penis enlarges and gets hardened. For the penis to get hardened with the sexual stimulation, depending on the signals sent from the central nervous system through the nerves, arteries expand and carry blood to the penis. Meanwhile, the veins narrow and do not carry the blood coming to the penis back and ensure that it is trapped in the penis. In other words, for a healthy erection, firstly the nerves and the vessels need to function healthily. Also, hormones play important roles during erection process.
