Q: After ejaculation, but my ding is still hard. Is it normal? A: If you just have an erection without any discomfort, it is considered a normal physiological phenomenon. This indicates that your erection is functioning well, which is a good phenomenon and does not require any special treatment. This phenomenon needs to be distinguished from abnormal erection of the penis. Abnormal penile erection is a state of persistent erection of the penis unrelated to sexual desire, usually for more than 4 hours. It often occurs suddenly under unexplained circumstances or is common in special cases such as after taking or injecting vasoactive drugs, and is a male emergency, so you need to go to the hospital promptly if you have a similar situation. However, this reader’s persistent erection was after the ejaculation of sexual intercourse and lasted for a short period of time. Therefore, the diagnosis of abnormal erection of the penis can be ruled out. What is abnormal erection of the penis? Xiao Gang was newly married, and the couple bathed in love whenever they had the leisure. One day during sex, Xiaogang’s penis continued to erect after ejaculation, which Xiaogang thought was a sign of his own vigor and energy, and fell asleep without taking it seriously. When I woke up, I found that my penis was not weak, and I was in pain, so I rushed to the hospital, but it was too late …… The medical term abnormal penile erection refers to a long lasting erection without weakness. This disorder occurs in young adults, other ages can also develop, the onset of the cause is more complex. The causes are complex, such as local inflammation of the penis, injury, tumor, leukemia, etc., which can trigger the disease, but most patients are not able to identify these possible causative factors. Clinically, it is called induced abnormal penile erectile disorder. Although the etiology is complex, there are three common causes: obstructed venous blood return to the penis; excessive arterial blood supply to the penis, both of which can increase blood filling in the penile corpus cavernosum and leave the penis in a state of sustained erection; and a disorder in the nervous system that controls penile erection. The main causes of abnormal penile erection (1) blood diseases: such as sickle anemia, leukemia, erythrocytosis and thrombocytopenia, etc. These diseases can cause blood deposition in the penile corpus cavernosum and lead to abnormal penile erection; (2) neurological diseases: commonly seen in spinal cord injury or inflammation and brainstem lesions, etc. Also seen in some patients after open-heart surgery where the spinal cord center is overexcited, leading to persistent penile erection. (3) Mechanical lesions: “such as trauma to the pubic area, advanced tumors of the pelvis, etc. These lesions can continuously compress the root of the penis, affecting blood return and erection without falling. (4) certain drugs: drugs that can cause persistent erection of the penis include lisinopril, compound hypotensive capsules, etc. Hemostatic drugs such as 6-aminoacetic acid and Valium may also cause. (5) Inflammation”: such as prostatitis, can cause prostate vein plexus embolism, affecting the return of deep veins, so that the erection of the penis does not fall. Once this disease occurs, you should seek medical attention promptly, do not be ashamed to delay the time.
