Abstract: | Microstructure and submicrostructure of Leydig cell and Sertoli cell in the testis of gonadal precocity and immaturation in cultured large yellow croaker, Pseudosciaena crocea, are studied using histology and electron microscopic technique. The results indicate that the fine structure of the two kinds of cells in different development stages presents an obvious difference. The smooth endoplasmic reticular and tubular mitochondria of Leydig cell and Sertoli cell are well developed in the testis of gonadal precocity, but poorly developed in the testis of immaturation. We suggest that the reason for gonadal precocity in the large yellow croaker may be related to the earlier development and maturation of Leydig cell and Sertoli cell. |
