It was divided in two groups, in one group it was used radiofrequency and pelvic exercises and in the other turned off radiofrequency (heated glycerin) and pelvic exercises. It was accomplished in eight sections. As a result, it is expected the efficiency of the treatment of radiofrequency in the quality of life, in sexual function and in it's severity.
