It is not just today that the matter has emerged, and the same process of understanding other physical phenomena, people’s understanding of ED, is also slowly from superstition to science. Erectile dysfunction (ED) is a long-term (at least 6 months) inability of the penis to achieve and maintain adequate erectile hardness, which can lead to a lack of pleasure for the patient and his or her partner. In China, ED is commonly referred to as “impotence” and “inactivity”, while in the West it was earlier referred to as “impotence”. From these names it can be seen that people dislike this condition. The God of Impotence and the Pulley Lever In ancient times, people often associated things they could not solve and could not explain with God, and often appealed to religion. In the ancient West, for example, many ED sufferers would turn to priests. In the Middle Ages, there was a legend that spread widely: the god of impotence can do magic on the penis, and witches can summon the god of impotence through the ritual of tying a knot in the belt to make someone suffer from ED. Hippocrates, a physician in ancient Greece during the time of Berkeley, believed that human disease was the result of an imbalance of the body’s four fluids (blood, black bile, yellow bile, mucus) (the doctrine of body fluids). He believed that “vital energy” flowed into the penis to stimulate an erection (we now know that it is the blood that makes the penis erect), but that an imbalance between the four elements of water, fire, earth and air and the four fluids caused ED. Hippocrates also believed that the testes and the penis could form a pulley-like system, with the penis passing through a “pulley” on the “testes”. -The penis is pulled by the “thread” on the pulley – the testicles – and erected, and without the pulley the penis naturally cannot be erected. However, research on castrati (such as Chinese eunuchs – except for those whose penises were also cut off – and Italian castrati – such as Farinelli) found that many “men” without balls ” can still get an erection and even maintain an active sexual function. It seems that this pulley said completely unreliable. The Body-Mind Debate In the late 19th century, there was a heated debate between advocates of the organic theory of ED and the psychosexual theory. Thomas (Thomas) found that excessive sexual intercourse or masturbation in men can make the erectile center less sensitive and trigger ED, while Krafft (Krafft), Ellis (Ellis) and Freud (Freud) and other representative figures of psychosexual theory have another set of claims. For example, Freudian psychoanalytic theory that: the son’s Oedipus complex, in his adult and will transfer this adoration to another person’s body, will cause him to produce psychological conflict, thus inducing ED. (immediately remembered the old Friends of Rachel COS Star Wars Princess Leia episode.) In modern times, people found that from medical to surgical, from physical to psychological, can cause ED too many reasons. Until today, people have not fully understood the cause of ED, let alone the cure. It seems that the revolution has not yet succeeded, doctors still need to work hard ah.
