An abnormal penile erection is a strong, persistent and unremitting erection. What’s even stranger is that this symptom usually occurs in people who were previously unable to get an erection at all. Strange to say, does that mean the disease is not cured? If you think so, you are very wrong. Let’s take a look at the dangers of abnormal penile erection. First of all, let’s popularize what is abnormal penile erection Abnormal penile erection is a state of persistent erection of the penis that is not related to sexual desire. An erection that lasts more than 6 hours is considered an abnormal erection. Traditionally, abnormal penile erection is divided into primary (atopic) and secondary. According to hemodynamics, they are divided into low blood flow type (ischemic) and high blood flow type (non-ischemic). The former is due to venous obstruction (veno-occlusive) and the latter to abnormal arterial blood injection (arterial). Abnormal penile erections are also classified as acute, intermittent (recurrent or intermittent, as in sickle cell anemia), and chronic (usually the high blood flow type). Initially, all abnormal penile erections are physiological penile erections, which later develop into the high blood flow type. The next look at the abnormal erection of the penis will bring what kind of harm 1, lies in the cavernous body of blood stagnation, blood viscosity, oxygen partial pressure and acid-base (pH) decreased, carbon dioxide content increased, six hours after the onset of these changes can be seen, if not timely treatment will further cause cavernous interstitial edema, and eventually lead to thrombosis of the main output veins, ischemia and hypoxia make the patient feel severe pain. 2, also have an impact on fertility: according to the onset, clinically divided into primary and secondary two categories, primary abnormal penile erection is mostly seen in adults, no obvious cause; children are mostly secondary, hematological disease is the main cause of secondary abnormal penile erection, accounting for about 20% of all cases, including sickle cell anemia accounted for the majority of other secondary causes because of neurogenic, trauma, inflammatory Infection, chemicals, toxins, cancer, congenital defects, etc. 3. If the low blood flow type lasts for several hours, the penis is painful due to tissue ischemia and the erection is hard. In the high blood flow type, the penis is rarely painful and the penis cannot achieve full erectile hardness. There is usually a history of perineal or penile trauma. In most cases of this type, the penis can regain full erection after arterial embolization or surgical ligation of the blood vessels, but it usually takes several weeks to several months. Finally, so if you find yourself with an abnormal erection, go to the hospital at the first opportunity and do not delay the best time to treat it, so as not to affect your normal life in the future.
