Relationship between sperm motilityparameters and sperm morphology
Abstract：Objective To investigate the relationships between sperm morphology and sperm motility param-eters.Methods One hundred and forty-nine semen samples were tested .Sperm motility parameters were analyzed by computer-aided sperm analysis(CASA), and the sperm morphology was observed by Diff -Quik rapid staining.Sperm morphology and motility were classified based on the “WHO laboratory manual for the examination and processing of human semen”( Fifth Edition) .Some of the samples were morphologically normal ( normal group ,n=75 ) and the others were morphologically abnormal ( abnormal group , n=74 ) .Results VCL, VSL, VAP, ALH and BCF were significantly higher in the morphologically normal group than those in the abnormal group ( P<0.01 ) , but there were no significant differences in LIN , WOB and STR between the two groups ( P>0.05 ) .There were significantly posi-tive correlations between the morphologically normal sperm rates and VCL , VSL, VAP, ALH, BCF.The percentage of the sperms that only had the abnormal heads was positively correlated with VSL , VAP, VCL,LIN, STR, ALH and BCF.The percentage of multiple abnormalities sperms was negatively correlated with VSL , VAP,VCL, LIN, STR, ALH and BCF .Conclusion There are correlations between sperm morphology and sperm motility parameters .Ab-normal sperm morphology influences the movement velocity , the space displacement and the movement way of sperms.The sperms with only head deformity are not the decisive factors affecting the sperm motility rate and the de-gree of space displacement .Multiple abnormalities may be one of the main reasons affecting sperm motility .
