It has been already suggested that specific macromolecules in follicular fluid produced by granulosa cells may play a role in suppressing further meiotic maturation of the oocytes. In general, the search for specific macromolecules in follicular fluid using immunological methods has not been rewarding. These studies were designed, by applying more effective immunological methods than conventionally employed, (l) to identify whether some unknown macromolecules are present in the porcine follicular fluid or not, and (2) to clarify the relationship between the oocytes and the specific macromolecules in the follicular fluid. The results obtained were as follows; (1) porcine follicular fluid contained two specific proteins, which were not present in pig plasma and serum. (2) each of two proteins showed electrophoretically fast alpha-globulin and beta-globulin mobilities. (3) these proteins seemed to have inhibitory effect on the maturation of mouse oocytes in vitro. From these results, it can be assumed that pig follicular fluid contains specific proteins which seem to be intra-follicular inhibitor(s) of oocyte maturation.
