The macroscopic anatomy of gubernaculum testis and processus vaginalis has been carefully studied during 150 consecutive orchiopexies. In subcutaneous and canalicular testes a well defined gubernaculum was found representing a morphologic continuity from the testis to the bottom of the scrotum. The gubernaculum was detectable in only one of four abdominal testicles. In 75% of the patients the serous communication between the testis and the abdominal cavity was lost. 43% of the patients still had a detectable rest of the processus vaginalis of which one third presented with a clinical hernia.
