Effect of Spermine on Divalent Cations of Human Spermatozoa

Abstract
The present report deals with the effect of spermine (0.4-2.0 mg) on the intracellular levels of calcium, magnesium, sodium, and potassium in human spermatozoa. Spermine decreased the calcium and magnesium levels in a dose-related manner; however, changes in the sodium and potassium levels could not be correlated with spermine concentration.
