Table 1 Seasonal values of melatonin, testosterone and antioxidant enzyme activities in ram seminal plasma

From: Seasonal variations of melatonin in ram seminal plasma are correlated to those of testosterone and antioxidant enzymes

	Breding season	Non breeding season
	(n = 28)	(n = 20)
Melatonin (pg/ml)	137.51 ± 17.8^a	46.57 ± 8.37^b
Testosterone (ng/ml)	28.13 ± 3.35^a	10.66 ± 2.92^b
GPX (nmole/min.ml)	61.57 ± 4.48	52.86 ± 8.53
GRD (nmole/min.ml)	11.82 ± 0.84^a	7.5 ± 0.47^b
SOD (mmole/min.ml)	8.86 ± 0.15	8.56 ± 0.26
Catalase (μmole/min.ml)	2.11 ± 0.25	1.74 ± 0.19

Values are shown as mean ± S.E.M. of the number of the number of seminal plasma samples assessed in brackets. Different letters in the same row account for significant differences between seasons (P < 0.01)
