Zinc concentration and content of the dorsal, lateral and medical prostatic lobes and of periurethral adenomas in man.

The concentration and content of zinc in the prostatic lobes and in periurethral adenomas, when present, were determined in an autopsy series of 45 adult males by atomic absorption spectrophotometry. The zinc distribution within the prostate was found to be related to the anatomically defined lobes, the dorsal lobes having the highest, the medial lobes the lowest and the lateral lobes intermediate zinc concencentrations. The differences in zinc concentration between the lobes were leveled in individuals who died from chronic disease, except in cases with periurethral adenomas, Periurethtral adenomas had higher zinc concentration than prostate proper.
