Spermatogenesis‐related change in the synthesis of the creatine kinase B‐type and M‐type isoforms in human spermatozoa

1 Mar 1990

Abstract excerpt

We have demonstrated earlier that the per sperm creatine-N-phosphotransferase (CK) activity was increased in oligospermic vs. normospermic men. The increased sperm CK activity is related to higher concentrations of cellular CK, which may indicate a defect of cytoplasmic extrusion during spermatogenesis. In the present work, we examined whether in spermatozoa, similar to muscle, there is a change in the synthesis...
