| Abstract | ||||
| Inguinal hernia is a mammalian lesion due to the presence of the inguinal defect. This defect is present to allow extra-abdminal position of the testis, to attain the temp- ,erature required for the process of spermatogenesis. In birds, the testis is cooled by being situated near the air sae; (Romer and Pfl,rsons, l9?7). 'This can explain the intra-abdominal position of the testis in non-mamm- .alian species. As the muscl€s and ttre fascia,e of the anterior abdominal wall differentiate around the gubernaslum, the muscles split around iU (Arey, 1966, Davies, 186?, and Scorcer, and Farrington 1956). The hole through which the testis-and its cord-passes, is present in the lateral psrt of tlte defect, while its medial part is formed by tlre deepest fascial Iayer of the abdomen, supported by some fibres from the aponeurosis of the deepest muscle. | ||||
