title: Zinc and magnesium in bull and boar spermatozoa.
abstract: Mean +/- s.e.m. concentrations (nmol/10(8) cells) of zinc and magnesium in bull spermatozoa were 30.6 +/- 6.6 and 119 +/- 28.8, respectively. Corresponding values for boar spermatozoa were 16.9 +/- 1.98 and 57.1 +/- 4.3. Bull spermatozoa washed twice in a standard buffered salt solution, pH 7.75, lost 72.6% of their zinc and 46.5% of their magnesium. Boar spermatozoa lost 40% of Zn and 18% of Mg, respectively. Addition of albumin (4% final concentration) to the washing solution did not increase the loss of ions from bull spermatozoa but increased the loss of zinc and magnesium from boar spermatozoa to 52% and 41%, respectively.
