Schematic drawing of the experimental design. Inline graphic Saline Group, animals received an intratesticular injection of sterile saline solution. Inline graphic MF Group, animals received an intratesticular injection of the magnetic fluid. Inline graphic AC Group, animals were exposed to the external AC magnetic field only. Inline graphic Inline graphic MNH Group, animals received an intratesticular injection of the magnetic fluid and were exposed to the external AC magnetic field. Animals were divided into 3 subgroups and evaluated: 7 (MNH-D7 Group), 28 (MNH-D28 Group), and 56 (MNH-D56 Group) days after the magnetic nanoparticle hyperthermia treatment.
