Effectiveness of Viagra:

• Viagra (sildenafil) works by increasing blood flow to the penis, aiding in achieving and maintaining an erection when sexually stimulated.
• It does not create a feeling of arousal but facilitates the physical process needed for an erection.

How it Works:

• Viagra relaxes blood vessels in the penis, allowing more blood flow during sexual arousal.
• It requires sexual stimulation to be effective and does not cause spontaneous erections or increase sexual desire.

Considerations:

• Many men with erectile dysfunction find it effective, but results can vary.
• Consult a healthcare provider for personalized advice, especially if you have underlying health issues.
