Testicular mass (mean+SEM) of male pigeons treated with two different doses of cypermethrin (10 and 20 mg/kg bw) and the aqueous extract of PO (300mg/kg bw) for 10 weeks, and subjected to long photoperiod (19L: 05D) (n=5).
a, Significant difference between the control, CYP1 and CYP2; b, Significant difference between the positive control, CYP2 and CYP2; c, Significant difference between CYP1+PO, CYP1 and CYP2; d, Significant difference between CYP2+PO, CYP1, and CYP2, e, Significant difference between CYP1 and CYP2.
