This well-known ED tablet, Viagra (Sildenafil), comes in a recognisable blue pill form. It assists men in achieving and maintaining erections during arousal by relaxing vessels and muscles leading to the penis. This enables increased blood flow to fill and harden things when excitement strikes. The NHS estimates around 50% of British men aged 40-70 wrestle with erectile issues that disrupt enjoyment of intimacy.

In essence, Viagra works by enabling more rapid blood flow to fill erectile tissue below the belt when turned on. The outcome is facilitated rigidity and endurance for relations once hindered for couples. Bringing awkward questions to one's doctor can unlock solutions where hindrances once existed. As they say, today's cures arise from yesterday's uncomfortable conversations. In this guide, we'll cover all you need to know about how Viagra works and what it does.
