Fig. 1.

Sperm cells normal versus asthenozoospermic samples. Purple dots are for the asthenozoospermic samples and blue dots are for the normozoospermic samples. Upper panel is the PCA when all the proteins quantitated were considered for the PCA, middle panel is when only housekeeping proteins (FC 1.0 to 1.29) were considered for PCA. Lower panel is when only the proteins having ANOVA p value less than 0.05 and fold change more than 2 in either condition were considered for PCA.
