The Interaction of Ph, Tonicity, and Electrolyte Concentration on the Motility of Fowl Spermatozoa

Abstract

The motility of fowl spermatozoa has been studied in vitro under various modifications of pH, osmotic pressure, and chemical composition of diluents. The glucose and sodium chloride content of the diluents has been varied to give tonicities ranging between that of 0·45 and 1·8 per cent. sodium chloride. Tliese diluents were buffered with citric acid-disodium phosphate, sodium phosphates, or sodium carbonate-bicarbonate mixtures which were equally innocuous.
