Abstract
The water content of epididymal bull spermatozoa in media of osmolalities corresponding to those of seminal plasma and to the fluids from the cauda epididymidis was determined by a gravimetricvolumetric method as 0·586 ± 0·0052 and 0·512 ±0·0086 ml per ml of cells, respectively. It was related to the ionic concentrations in mmol/ litre of spermatozoa determined by the conversion of the mean values of the major cations expressed as mequiv./litre, mg/100 g, or mg/100 ml, established by previous authors. The osmolalities of the intracellular fluids were also calculated. They were compared with the osmolalities of the extracellular fluids, the comparison making it possible to perform an introductory analysis of the osmotic-equilibrium states of bull spermatozoa.Keywords
