[Effect of magnesium deficiency and dietary overload in the male rat: magnesium levels in the various compartments of the reproductive system].

Groups of rats were maintained in Mg2+ deficient, Mg2+ overloaded and control diets for two weeks. Mg2+ deficiency caused an acute hypomagnesemia without any effect on Mg2+ level of testis, epididymis spermatozoa, or seminal fluid while Mg2+ overloading implied hypermagnesemia and increase in testis and sperm Mg2+ level.
