Kamagra oral jelly is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient sildenafil citrate, which works by increasing blood flow to the penis, resulting in an erection.

When a man is sexually aroused, the body releases nitric oxide, which stimulates the production of cyclic guanosine monophosphate (cGMP). cGMP helps to relax the blood vessels in the penis, allowing blood to flow into the penis and resulting in an erection. However, in men with ED, this process may be impaired, making it difficult to achieve or maintain an erection.
