Sildenafil for ED is a drug that treats erectile dysfunction (Ed) which is basically defined as impotence; lack of ability to erect or keep the penis erected in men. This happens when there’s no sufficient blood flowing to the penis. Therefore, Sildenafil manages ED by increasing blood flow to the penis during sex. It’s this increased blood flow that results in an erection.
In the US alone, ED is said to affect 30 million men, in some patients who totally can’t get an erection while in others Erectile dysfunction is an occurrence that comes once in a while. A study done on male aging in Massachusetts revealed that 52% of 1,290 studied affirmed that they had some degree of erectile dysfunction. Sildenafil falls in a class of drugs called phosphodiesterase inhibitors PDE5.
It’s important to note that Sildenafil doesn’t treat ED nor increase libido which is a sexual desire. Far from the notion, it doesn’t also prevent or increase the spread of Sexually Transmitted Diseases (STDs) like Gonorrhea or human immunodeficiency virus (HIV).
