The orientator method for producing the isotropic uniform random (IUR) sections. (A) The cylindrical paraffin-embedded ovary was placed on the Φ clock. After choosing a random number between 1 and 9, the paraffin was cut at that direction (here, it was 5). (B) Then, the paraffin cylinder was located in the 0-0 direction of the θ clock from the cut edge and underwent the second cut at a random number (here, it was 3). Both of the cuts were done in the ovary-free parts of the cylindrical paraffin.
