I understand your question and concern about genital warts. They are caused by a virus called human papilloma virus or HPV. Sometimes warts will be widespread or not responding to medication like creams you applied. In such cases, surgeries will be required to treat them. But the success rate of surgery is also not good and warts seem to re-appear in about 50% of cases. One of the widely used method to treat genital warts is cryogenic method. In this method, warts are frozen killed with the underlying tissue. This can be done in a hospital by a doctor who is used to it. This is mostly used if the warts are widely spread or if there are a number of warts in a small area. Creams also can be used to do this process. Moreover there are over the counter kits to do the treatment at home. Those kits are called freezing kits. Only creams can be used in situations where the warts are in a sensitive area so that freezing cannot be done. Freezing is usually done by doctors using liquid nitrogen. After the treatment, warts will fall off and disappear in a matter of a few days. If they seem to reappear, the same treatment is given again or some tropical medication is tried. In cases where these methods too fail, surgical removal of warts only can be done.
