Using Cenforce 100 USA may assist with erectile dysfunction (impotence). Impotence, often known as erectile dysfunction in males, is the inability to achieve and maintain a hard enough erection for intercourse. The preferred pharmaceutical therapy for erectile dysfunction is an oral pill called a PDE 5 inhibitor (ED). This drug prevents PDE-5 enzymes from causing flaccidity in the penis. It eases blood vessel tension, improving blood flow to the penile region.
