Abstract
NORMAL human seminal plasma has been shown to contain a higher concentration of zinc than any tissue except sperm1. The sperm contain a very high concentration of zinc, but their removal from semen by centrifugation causes no significant reduction in the zinc concentration of the fluid because of their small relative volume. No previous opportunity had occurred for analysis of naturally aspermic semen, but recently a specimen of this nature was received. It had not been collected in specially cleaned glassware, but any contamination due to this fact could not have added more than a few µgm./ml. to the zinc content.
