Cytoplasmic Extrusion and the Switch From Creatine Kinase B to M Isoform are Completed by the Commencement of Epididymal Transport in Human and Stallion Spermatozoa
2 Jan 1998
Abstract excerpt
Although in several species there is a relationship between epididymal sperm transport and fertility, in human in vitro fertilization (IVF), spermatozoa recovered from the caput epididymidis or even the rete testis are fertile. We studied two objective markers of sperm maturity in the sperm of men and stallions: creatine kinase (CK) concentrations, which are a measure of cytoplasmic retention in immature...
