follicular fluid electrolytes and osmolality in cyclic pigs.
Sodium and osmolar concentrations of porcine folliclar fluid in the cyclic pig did not vary significantly during the oestrous cycle, and were similar to those in plasma. The K+ concentration was greater in small (Days 12-13) and medium-sized (Day 16) follicles than in plasma or large (Day 18-oestrus) follicles of cyclic sows. In contrast, follicular fluid obtained from slaughterhouse material had higher potassium and osmolality, and lower sodium values, which are assumed to be due to post-mortem changes.
