How Viagra works?
The penis gets erect during sexual stimulation when increased blood flows
to the penis resulting from relaxation of penile arteries and corpus cavernosal smooth muscle.
This is due to the release of nitric oxide (NO) from nerve terminals and endothelial cells
which in turn leads to the synthesis of cGMP in smooth muscle cells.
Try Viagra now!
