What is the latest and most effective treatment for genital warts.. does freezing them off keep them at bay for longer?

Warts: Warts can be treated either by "burning" them using concentrated special acid solution, using creams like Aldara (imiquimod) that stimulate immune response on your skin where the wart is, or by freezing them. Each one treatment should be tailored to specific manifestation of disease in your case, and to your desire as well. So best thing get an appt with a gynecologist and discuss in detail.

Topical treatment: There is also a fairly new topical medication called veregan ointment that contains a chemical derived from green tea that helps to kill the hpv virus. It requires a prescription.
