Frequently Asked Questions

 

 

How does Viagra® get to work?
Erectile Dysfunction is often a physical problem. Viagra® treats erectile dysfunction by increasing the blood flow to the penis. With Viagra® you must be sexually excited to get an erection. If you take Viagra® when you are not aroused nothing will happen. You will not get an erection just by taking Viagra® .

When a man is sexually excited following sequences would take place:
1. The arteries in the penis relax and widen (this allows more blood to flow into the penis). 2. The increased blood flow causes the penis to become hard and erect. 3. The veins that normally carry blood away from the penis get compressed (this restricts the blood flow out of the penis). 4: More blood begins flowing in and less flows out, making the penis larger; this causes an erection.   For most men the nerves or blood flow plays its part to work this process properly. For others this might not be the case.
