E. aMethods for semen evaluation I. Density, respiration, glycolysis of semen.h[electronic resource] c1939 aTwo methods of estimating density which require less time and are of equal or greater accuracy than the haemocytometer have been described. The first is especially useful for field work because of the simplicity of the equipment. Evidence for the use of glycolysis rate as an indication of viability has been reported. The results obtained seem logical since glycolysis is a physiologic necessity to motility. The use of rate per unit volume is recommended since it is weighted by density, another factor positively correlated with viability. The morphological picture and glycolysis rate should be used to supplement each other in evaluating semen since they are both important to fertility and as yet the relation between them is uncertain. aReproduction aSheep aBioquímica aOvino aReprodução aSêmen aAndrologia1 aGREEN, W.
