Research Abstract

Seminal vesicle secreted protein, semenogelins(SEMGs) are one of inhibitory factor for hyperactivation of sperm motility. Our previous study has revealed that SEMGs were also inhibitory factors for acrosome reaction and protein tyrosin phosphorylation. Collectively, SEMGs may be inhibitory factors for sperm capacitation. However, it is still unclear that the direct interaction between lipid lafts and SEMGs. Our study suggests that SEMGs can bind to cholesterol and effect on sperm membrane fluidity and on function for capacitaion.
