title: follicular fluid electrolytes and osmolality in cyclic pigs.
abstract: 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.
