The study's objective is to evaluate the enhanced effect of Ghrelin (GRE) on sperm analysis and the antioxidant system in male rats after inducing hyperthyroidism by L–thyroxin. The rats (50 males) were split into five groups. The first group consisted of 10 male rats that were given normal saline for 30 days S.C and set as a control group. While the second group (positive group) was 10 male rats with hyperthyroidism were given normal saline for 30 days S.C, the third group was 10 male rats with hyperthyroidism were given Ghrelin at a dose of (0.5nmol/100μl saline) for 30 days S.C, and the fourth group was male 10 rats with hyperthyroidism were given Ghrelin (1nmol/100μl saline) for 30 days S.C. The fifth group consisted of 10 hyperthyroid male rats that were given Ghrelin at a dose of (2nmol/100μl saline) for 30 days S.C. The results show a significant (P≤0.05) decrease in all parameters of sperm analysis, the number of births and antioxidative system in hyperthyroid group compared to control group. While, all treated groups with GRE (0.5, 1 and 2 nmol) shows enhance effect in sperm analysis, the number of births and antioxidant system compared to the hyperthyroid group.
