Abstract

Ram spermatozoa in fructose-free Ringer-phosphate medium were treated with antimycin A to arrest collective motility, then with fructose (5 mg/ml), 10-70 min after antimycin. The interval from reactivation with fructose to max. collective motility increased from 3.5±1.3 min for reactivation 10 min...

Abstract

The method described is suitable for ejaculates containing 1 X 109 to 2 X 109 spermatozoa/ml. Changes in the intensity of light scattered from semen samples at 38 deg C are recorded as analogue waves; the frequency of the waves was directly correlated with motility determined by light microscopy....

Abstract

The present work was carried out to determine if the reduced CR of ♀♀ exposed to high concentrations of progestogens and oestrogens could be related to a direct effect of these hormones on spermatozoa. Ejaculated ram spermatozoa were treated with the respiratory inhibitor antimycin A, so that...

Abstract

A new instrument based on varying optical density determinations, for the measurement of sperm concentration and collective motility of the fresh semen of bulls or rams is described. The optical density is converted to give a direct estimate of sperm concentration in undiluted semen in the range...

Abstract

Addition of testosterone to the incubation medium was followed immediately by a decrease in collective sperm motility. This occurred whether motility was driven by mitochondrial fatty acid β-oxidation (by exposure to 2-deoxyglucose), the Embden-Meyerhof pathway (by exposure to antimycin A), or by...
