Erectile dysfunction (ED) is essentially the inability to produce penile erection in men. This crucially limits their ability to take part in sex as penile erection is needed for vaginal penetration. There are two forms of erectile dysfunction – psychological and physical. Psychological ED is just in the brain. Issues like depression, anxiety, or guilt can prevent a man from having an erection. However, once those issues have been cleared, the usual normal erectile function will resume. With physical ED however, it is much different as there is actually a physical cause that prevents a man from having an erection.
There are many factors that can cause a physical type of erectile dysfunction. This may include surgery, accident, trauma, disease, health condition, obesity, and many others. The factors that have been mentioned are however the most common causes. In the past, there was no cure for ED. However, during the late 90s, the discovery of PDE5 inhibitor treatment was made and everything changed for all those who suffer from male impotence. This is because PDE5 inhibitors like sildenafil generic have the capacity to effectively treat erectile dysfunction in men.
