Kamagra 100mg There is no clear evidence that Kamagra works for women. But the manufacturer of Kamagra offers a different alternative for women. The new drug produced contains exactly the same ingredients as Kamagra and works in the same way. While there is no evidence that Kamagra works for women, there are studies that show sildenafil (the active ingredient in Kamagra) can increase a woman's s*x drive, but also cause regular side effects such as headaches, hot flashes or indigestion. Sildenafil may also affect the lining of the uterus by thickening it. This makes it easier for the egg to settle and nest in the uterus.
