In males, indirect<unk> s follow the same route as the descending testes, which migrate from the abdomen into the scrotum during the development of the urinary and reproductive organs. The larger size of their<unk>  canal, which transmitted the testicle and accommodates the structures of the spermatic cord, might be one reason why men are 25 times more likely to have an<unk>  than women. Although several mechanisms such as strength of the posterior wall of the<unk>  canal and shutter mechanisms compensating for raised intra-abdominal pressure prevent<unk>  formation in normal individuals, the exact importance of each factor is still under debate. The physiological school of thought thinks that the risk of<unk>  is due to a physiological difference between patients who suffer<unk>  and those who do not, namely the presence of aponeurotic extensions from the transversus abdominis aponeurotic arch.<unk> s mostly contain the omentum or a part of the small intestines, however, some unusual contents may be an appendicitis, diverticulitis, colon cancer, urinary bladder, ovaries, and rarely malignant lesions.
