Impotence can be divided into:
- circulatory impotence – nowadays it is the most frequently diagnosed and covers almost half of impotence cases. The causes are vascular disorders after myocardial infarction, stroke, atherosclerosis, defects of the vascular system, hypertension. Atherosclerosis of the vessels supplying blood to the cavernous bodies of the penis prevents the cavernous bodies from properly hardening. This can make the erection take longer, incomplete hardening of the penis or premature erection to end.
- neurogenic impotence – its most common cause are injuries and diseases of the spine in which the erection center is located. Also, many neurological disorders lead to impotence, e.g. multiple sclerosis, diabetic neuropathy.
- Hormonal impotence – contrary to what many men believe, it is not very common. It accounts for 5-10% of impotence cases. It most often occurs during andropause.
psychogenic impotence – is more common in younger men. The reasons are fears, task-oriented attitude, sexual inhibitions, situational tensions, insecurity of oneself as a partner, fear of being ridiculed.
- mixed impotence – this is about 1/3 of the cases of impotence. Various combinations of the listed causes of impotence are found in it, with some chronic diseases being the best example. Thus, in the course of diabetes, impotence may be caused by hormonal disorders, vascular changes, and neuropathy. Urological diseases such as Peyronie’s disease or previous urological surgery (e.g. prostate removal) can also have a negative effect on the erection.
