Resumo: 	The structure of the male reproductive tract was described in Uca uruguayensis Nobili, 1901, by using histological methods, scanning electron microscopy techniques, and stereoscopic observations of fresh material. The aim of this work was to establish the functional changes associated with sexual maturation. The morphology of the first (G1) and second (G2) pair of gonopods was described. The male reproductive tract consists of paired organs: testes, and tubular and convoluted vas deferens (VD) ending with a terminal ampoule (TA).The (VD) is composed of three parts: anterior (AVD), medial (MVD) and posterior (PVD). The AVD and MVD are lined by a single layer of cubical cells. The PVD epithelial cells are columnar with elongated nuclei. The terminal ampoule comprises four interconnecting chambers and is externally surrounded by connective tissue. The study of testes and vas deferens at different times along the year suggests that U. uruguayensis has a single and continuous reproductive season from December to March. The TA has not been described in other brachyurans and this structure is novel to Brachyura.
