Destabilization of Human Sperm Membranes by Albumin, EDTA and Histidine

Destabilization of Human Sperm Membranes by Albumin, EDTA and Histidine Washed human spermatozoa produced significant amounts of lipid peroxides in the presence of cupric and ferrous ions. Depletion of the zinc content of the spermatozoa by albumin, histidine or EDTA strongly stimulated the metal catalyzed production of lipid peroxides. This indicates that zinc ions are important for the integrity of sperm membranes. Albumin is present in the follicular fluid and it is suggested that zinc depletion of the spermatozoa at the site of fertilization may induce a destabilization of the membranes and thereby be part of the capitation process. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Andrology Wiley

Abstract

Washed human spermatozoa produced significant amounts of lipid peroxides in the presence of cupric and ferrous ions. Depletion of the zinc content of the spermatozoa by albumin, histidine or EDTA strongly stimulated the metal catalyzed production of lipid peroxides. This indicates that zinc ions are important for the integrity of sperm membranes. Albumin is present in the follicular fluid and it is suggested that zinc depletion of the spermatozoa at the site of fertilization may induce a destabilization of the membranes and thereby be part of the capitation process.
