The Semi-thin section method was employed to study the gonad genesis,the process of sex differentiation and histological features in Neocaridina denticulata sinensis.The results showed that the gonadal primordium were presented in N.denticulata sinensis on the 5th day post fertilization.The time of the ovarian differentiation was earlier than that of testis,and the differentiation pattern of ovary and testis were different.The ovarian differentiation initiated on the 10th day post fertilization with the character of forming ovogonium,and the ovarian cavity formed in 23 days.The testis differentiation initiated with the character of forming the early testis cavity,which was filled with germ cells and stromal cells in 23 days.There were a large number of spermatogonia in testis and testis differentiation were finished in the 35 days.
