Abstract
Ejaculated and vasal sperm were obtained from men referred for vasectomy, and sperm nuclear elements were determined by X‐ray microanalysis. Sperm head zinc concentrations, expressed as the ratio Zinc to Sulphur, were significantly higher in ejaculated than in vasal sperm. A physiological sperm nuclear zinc uptake is discussed in relation to sperm chromatin decondensation. Copyright © 1986, Wiley Blackwell. All rights reserved
