Analysis of relationship between sperm morphology and sperm acrosin activity

Objective To study the relationship between sperm morphology and acrosin activities.Methods The sperm morphology was analyzed by amended Pap staining and the sperm acrosin activities were determined by spectrophotometer.Two groups were normal and abnormal group base on the percentage of normal sperm morphology.Results The acrosin activities of abnormal sperm morphology group were lower than that of normal sperm morphology(P=0.05).There were no correlation between the percentage of normal sperm morphology and sperm head malformation of normal group and the acrosin activities(p0.05),there were positive correlation between the percentage of normal sperm morphology of abnormal group and the acrosin activities(r=0.39,P0.05),while a negative correlation was found between percentage of sperm head malformation and the acrosin activities(r=-0.325,P0.05).Conclusion The sperm morphology could affect sperm acrosin activities.
