Kamagra Oral Jelly 100 mg is functionally effective for treating erectile dysfunction (ED) because it contains sildenafil citrate, the same active ingredient as Viagra.

It helps improve blood flow to the penis during sexual stimulation, making it easier for many men with erectile dysfunction to achieve and maintain an erection suitable for sexual activity.

However, it is important to remember that sildenafil does not cause an automatic erection. Sexual arousal is still required for the medication to work.
