Abstract: This study was conducted to determine the effect of added sulphur compounds, substrates and various inorganic ions on the metabolic activity of epididymal spermatozoa from twenty-one bulls and five goats. The addition of sulphur at physiological levels in the form of sulphide, sulphite, sulphate and glutathione in several different media caused no stimulation of respiration. An apparent stimulation of oxygen uptake by the addition of cysteine was shown to be due to auto-oxidation of the added cystein. Calcium and magnesium in a Ringerphosphate medium had no obvious effect on metabolism, while phosphate decreased oxygen uptake but increased glycolysis and lactate accumulation in the presence of substrate. Substrate, present even for a short period of time before removal, stimulated metabolism markedly during the subsequent incubation period. |
