Viagra belongs to a class of medication known as PDE5 inhibitors. In the presence of sexual stimulation, PDE5 inhibitors such as Viagra relax smooth muscle and increase blood flow to the penis, helping to restore impaired erectile function. Viagra will stay in the body on average 4 hours after dosing. For some men it may remain as long as 5 hours, or a few as 3 hours. Viagra is generally well tolerated and comes in a variety of dosages so the strength can easily be decreased for men experiencing bothersome side effects. The most common side effects include headache, flushing, indigestion, nasal congestion, dizziness, nausea, hot flush and visual disturbances. These common side effects are all transient in nature and should not last more than a few hours. Studies have not shown any effect on sperm motility or morphology.
