Abstract

Sperm nuclear zinc content (expressed as zinc/phosphorus and zinc/sulphur ratios) was determined with X-ray microanalysis in individual, air-dried, epididymal spermatozoa from elderly men, and in ejaculated spermatozoa from healthy donors. Ejaculated sperm nuclei contained (also after treatment with sodium dodecyl sulphate) more zinc than epididymal spermatozoa. The results indicate that the human spermatozoon accumulates zinc from the prostatic fluid upon ejaculation.
