title: Zinc and copper in human semen.
abstract: Investigations have been performed on the possible effect of zinc and copper on the fertility of man. Semen was obtained from 67 men and the zinc concentration was found to be decreasing with a drop of the activity of the semen. Copper was found in semen in microgram amounts which do not change with the activity of the semen. Results suggest that the zinc concentration may serve as evidence in the evaluation of semen activity.
