The Giraldes' organ – a rudiment or a functional structure of the funiculotesticular complex in man The Giraldes' organ represents a stable formation, consisting of convoluted system of canalicles that possesses a well developed glomerular vascular system, which forms anastomoses with the vessels of other components of the funiculotesticular complex. It was not found in laboratory animals and can be considered as a new phylogenetic organ, whose functional peculiarities are not known yet.

Organul Giraldes reprezintă o formaţiune stabilă, constituită dintr-un sistem de canalicule contorte şi vezicule ce posedă un sistem vascular glomerular bine dezvoltat, care formează anastomoze cu vasele celorlalte componente ale complexului funiculotesticular (CFT). El nu se depistează la animalele de laborator şi poate fi considerat ca organ filogenetic nou, particularităţile funcţionale ale căruia sunt încă neclare.
