The interaction of pH, tonicity and electrolyte concentration on the motility of dog spermatozoa


, : The interaction of pH, tonicity and electrolyte concentration on the motility of dog spermatozoa. Journal of Physiology 141(2): 273-280

The motility of dog spermatozoa as studied under conditions in which the glucose and NaCl contents of the diluents were varied to give tonicities ranging between 0.45 and 1.8% NaCl. These diluents were buffered with citric acid-phosphate, sodium phosphates, sodium carbonate-bicarbonate or veronal-hydrochloric acid mixtures. The sodium carbonate-bicarbonate buffer mixture depressed the motility of dog spermatozoa but the other buffers were without deleterious effects. Dog spermatozoa showed maximum motility in the pH range of 7.0-8.5. At a pH of 8.7-8.9, partial replacement of NaCl by glucose in isotonic and hypertonic diluents had no adverse effect on sperm motility. Under all conditions, hypotonic diluents were more deleterious than hypertonic diluents, containing the same components.
