A descriptive, analytical, and comparative study performed on cadavers of fetuses and adults of the male gender in the Anatomy Laboratory of the Medical School. We inform the embryological findings related with the normal testicular descent and highlight the fact that most pathological entities found in these patients originate in the male gonad, and that they were successfully resolved by means of surgical and medical treatment modalities, considering that this constitutes a complement of the primary study derived from anatomical dissection. We expect that this work, the fist of its kind in our region, will allow a better recognition of our Faculty of Medicine outside its original context.
