The relationship between sperm acrosin and anatomical parameters of sperm head

Objective To analysis affects of sperm acrosin by changing of sperm morphology during process of spern formation,and discusses the may ways of sperm formation.Methods 30 semen specimens were selected from secondary infertility patients,and sperm density≥20×106/ml and vitality≥50%.After the semen liquefaction,part of the that were analyzed sperm dynamic by computer aided,and part of the that were detected sperm acrosin,part of the that were analyzed sperm morphology by computer assisted with artificial correction.Results Compared with the sperm acrosin,there was significant positive correlation with the aspect ratio of sperm head(r=0.580,P=0.048),and a obviously negative correlation with apicle ratio(r=-0.614,P=0.034).Conclusion The sperm acrosin's formation is companied with the process of sperm forms gradually stretched thinner,cytoplasm condensed and gradually formed gradually lost.
