Aurogra 100 mechanism of action is similar to that of the brand drug Viagra, as they both contain the same chemical, Sildenafil Citrate. Erectile dysfunction is the process that involves many reactions. It starts in the brain and ends in the hardest male organ. When your brain receives a signal that men are receiving s*xual stimulation, Sildalist 120 responds with signals that cause the arteries to supply more and more blood to the male reproductive organ. As a result, it acquires hardness and remains in this state longer. Erectile insufficiency develops due to various factors that affect the normal process of blood supply. It ends with the loss of an organ that cannot perform the task.
