An important and frequent cause is the reduction in the amount of blood coming to the penis due to arterial narrowing (arteriosclerosis, diabetes, increased lipid and cholesterol, smoking, trauma, post-surgical damage) or increase venous blood flow away from the penis. Nervous system changes, following trauma or special surgical interventions, almost always result in erectile dysfunction.
Another not infrequent cause is La Peyronie’s disease which is characterized by fibrotic plaques of the tunicae albuginea and then also the corpora cevernosa of the penis that result in a curvature, which can cause pain during intercourse. Erectile dysfunction can also have a hormonal origin due to a lack of the hormone testosterone, which is rather rare, as well as an excess of hormone proliferation inhibitors.
What can you do about it?
An consultation with a psychologist can be very helpful if the impotence is caused by a psychological problem or if there is a strong component of anxiety. If the cause is vascular, a positive result can be obtained using some drugs such as Prostaglandin E1, which is administered by intracavernous injections, or Sildenafil Citrate (Viagra) and Apomorphine (Uprima) which are commercially available as tablets.
All of these medicines should be administered under strict medical supervision because, if misused, they can cause serious side effects. Finally, in the most serious or drug-resistant cases, surgery can be used to improve the blood supply to the penis or to insert a penile prosthesis inside the corpora cavernosa.
In any case, impotence can be treated: talking to a specialist will help you find the right solution for your individual case.
