Figure 3: Predictor loading profiles extracted from the first factor of final model. The variables near zero are not important in this factor, and the others contribute in one (+) or other (-) sense. TM: total motility; PM: progressive motility; BCF: beat cross frequency; RAP: percentage of rapidly moving cells; TM_2h: TM after 2 h of thermal incubation; PM_2h: PM after 2 h of thermal incubation; VAP_2h: VAP after 2 h of thermal incubation; BCF_2h: BCF after 2 h of thermal incubation; RAP_2h: RAP after 2 h of thermal incubation; HOST: intact plasma membrane evaluated by Hiposmotic Swelling Test; IPIA: intact plasma and acrosomal membranes evaluated by flow cytometry; IPM: total percentage of sperm cells presenting intact plasma membranes; IPNP: intact plasma membrane with no lipid peroxidation detected; IPP: intact plasma membrane suffering lipid peroxidation; Maj_Def: Major Defects; Tot_Def: Total of defects; WLR: Width:Length ratio; SAP: anterior-posterior symmetry; CV: chromatin heterogeneity; Concent: sperm concentration.
