Sperm ubiquitination in patients with dysplasia of the fibrous sheath

1 Aug 2002

Abstract excerpt

BACKGROUND: Human sperm with structural abnormalities display an increased content of the cellular proteolytic marker peptide, ubiquitin. We investigated whether dysplasia of the fibrous sheath (DFS), a severe structural anomaly found in the sperm of some asthenozoospermic patients, is accompanied by (i) increased ubiquitination of the sperm surface and (ii) by increased ubiquitination of the sperm mitochondria....
