What are the reasons for male erections? The ability of men to have an erection is not only related to their dignity, but also to the harmony of their sexual life. So, what are the causes of male erections?
What are the reasons for a man's erection?
Although the result of a male second birth erection is hard, the methods of erection are classified. It is generally divided into three categories: reflex erection, psychological erection, and nighttime erection.
The auditory, visual, olfactory, and thinking content related to male stimulation stimulates the cerebral cortex, which acts on the corpus cavernosum of the penis through the thoracolumbar erection center of the spinal cord, expanding arterial blood vessels, and a large amount of blood flows into the corpus cavernosum of the penis; Venous blood vessels contract, resulting in a decrease in blood flow from the corpus cavernosum. Blood is completely trapped in the abundant blood vessels and sinuses of the corpus cavernosum, causing the penis to rapidly develop a psychological erection. On the contrary, when arterial blood vessels contract, the flow of blood into the corpus cavernosum of the penis decreases; When the venous vessels dilate and the abundant blood flow trapped in the sponge rapidly returns, the penis regains weakness.
When the external genitalia is subjected to local stimuli such as direct contact, walking friction, or internal stimulation of the rectum and bladder, it can cause reflex erection, stimulating its sexual excitement by stimulating the lower erectile center of the sacral cord in the spinal cord. Penile erection is innate, and male fetuses can have an erection in the uterus.
A little boy may also have a hard erection during urination after birth. Sometimes lying there urinating can cause urine to spray directly onto the adult's face like spring water, which usually brings unexpected laughter and joy to parents who are changing diapers, but at this point, an erection has no sexual significance. Reflective erections can be induced through the perineal nerve and sacral spinal cord erection center.
These two psychological and physiological stimuli can not only work alone, but also interact and participate in sexual activities together. For example, when spinal cord injury occurs above the chest and waist, patients can only achieve an erection when their genitals receive physical stimulation, and their ability to achieve a psychological erection disappears. When motor neuron damage occurs below the chest and waist, stimulating the genitalia does not cause an erection, but 24-57% of patients still have a psychological erection, which means that psychological stimulation can be transmitted through the chest and waist. When spinal cord injury occurs between waist 2 and sacrum 1, both psychological and reflex erections exist, but the two cannot be coordinated and ejaculatory climax cannot be achieved through genital stimulation.
In addition to psychological and reflex erections, normal males also have nighttime erections. Men's sleep is always in an alternating state between fast eye movement sleep and slow eye movement sleep, and undergoes a physiological process of erectile flaccidity re erectile weakness, medically known as penile nocturnal erection, which is a normal physiological process for healthy men.
Generally speaking, men have 4-6 erections every night, each lasting 20-40 minutes, for a total of two and a half hours. This is because the brain always has an inhibitory response during the day, otherwise men will inevitably encounter awkward situations. However, after sleep, the inhibitory function of the brain disappears, and the penis will spontaneously have an erection response. This is completely normal and there is no need to worry.
The duration, frequency, and hardness of nighttime erections decrease with age, with puberty reaching its peak around the age of 20. Whether it is a psychological or reflex erection, the penis quickly returns to normal after external stimuli are eliminated. Erections at night are no exception. After an erection for a period of time, the penis will definitely weaken automatically, because if the blood stays in the sponge for a long time, it will lack oxygen and accumulate a large amount of metabolic waste, which is detrimental to the tissue and can lead to necrosis in severe cases. The disease of abnormal penile erection is characterized by persistent swelling, hardness, pain, and bluish gray of the penis for 4 to more than 6 hours. This is an emergency situation in urology and requires urgent treatment at the hospital as soon as possible. So the penis is not an erection that lasts all night, but must be relaxed. Morning erection is a meaningful clinical physiological phenomenon.
Some doctors have specifically studied this phenomenon and found that men's erections weaken or disappear in the morning; After the body recovers, an erection will also recover in the morning. Therefore, the phenomenon of morning erection can serve as a reference indicator for male health status. Morning erection can also serve as a reference indicator for assessing male sexual function status.
