It is inseed by withdrawal technique. Sounding is done prior to copper T inseion to check the uterocervical length and also to know whether the uterus is anteveed or retroveed. Hysteroscopic method is used for inseion of ESSURE coil into fallopian tubes, a method of female sterilisation , and not for copper T inseion.
