Figure 4. Computer Assisted Semen Analysis (CASA) of canine sperm exposed to testicular concentrations of PCB153 and DEHP.
(a–d) Effects of PCB153 and (e–h) DEHP are shown for (a,e) percent sperm linearity, (b,f) percent sperm motility, (c,g) percent straightness and (d,h) straight line velocity. Overall chemical effects are shown (n = 7 dogs). Note: chemicals were tested at 2x, 10x, 100x mean testis concentration [mean testis levels for PCB153 0.063 ± 0.01 ng/g (n = 34) & DEHP: 0.182 ± 0.044 ug/g (n = 25)]. There was no interaction with concentration or time. Predicted values from general ANOVA model are presented. *P < 0.05. NS = not significant. Error bar = SED.
