Men's erectile dysfunction and impotence are efficiently treated with the male enhancement drug sildenafil 200 mg (ED). Sildenafil works well because it eases the muscles that surround the male organ, guaranteeing that there are no problems with blood circulation. Science states that it stops an enzyme known as cGMP-specific phosphodiesterase type 5 from destroying cGMP. This approach is referred to explicitly as a recommendation for people who struggle with erectile dysfunction issues and find it difficult to sustain a strong erection despite repeated periods of impotence.
