The ED is often a symptom, not a disease. One of the main causes of disorders is narrowing of the blood vessels responsible for erection. Achieving an erection is the result of complex processes that take place in our body. Sexual arousal includes the interaction between the nervous system, the circulatory system, the muscles, the hormonal system, and the emotions controlled by the brain. States such as diabetes and stress can have a negative impact on these areas of our body, contributing to erectile dysfunction, which leads to libido disorders and a general deterioration in our sexual performance.Liberator X2
