Gynecologic Cryosurgery. ... The purpose of cryosurgery is to destroy dysplastic cells that arise in this transformation zone by effecting cryonecrosis. ... The external temperature of the probe depends on the conductivity of the probe material. Silver and copper are the best materials for use in probe tips because high conductivity produces both a better freezing effect and more effective local cryonecrosis.
