The Metabolism of Ram, Bull, Dog, and Rabbit Spermatozoa After Cooling to 5°C

Abstract

The possible occurrence of shunt activity in ejaculated ram spermatozoa was investigated by measuring the amount of labelled carbon dioxide and lactate formed from specifically labelled glucose by the cells. There was no evidence that ram spermatozoa, either shortly after collection or after storage at 5°0, oxidized glucose by the hexose monophosphate pathway.
