Ovary weight (mg tissue/pair ovaries)	24.13 ± 3.0	23.11 ± 1.6	28.25 ± 3.7	27.57 ± 3.2	25.78 ± 2.6
Ovary (pg NE/mg)	157 ± 48	215 ± 27,5	231 ± 35^a	375 ± 65.9^b	216 ± 20.2
Plasma (pg NE/ml)	52.65 ± 9	48.9 ± 9	40.78 ± 9	35.95 ± 10	47.1 ± 11
Celiac Ganglion (ng NE/ganglia)	69.79 ± 8	55.5 ± 10.1	60 ± 14	22.8 ± 8.9^c	30.2 ± 10^c
Adrenal (μg catecholamines/mg)	2.14 ± 0.25	2.80 ± 0.6	3.82 ± 0.32	2.98 ± 0.21	3.7 ± 0.33

Results are mean value ± SEM of n = 5 experiments in each age. (a) p < 0.05 vs 6, 8 and 14 months old, (b) p < 0.05 vs all groups studied, (c) p < 0.01 vs 6, 8 and 10 months old.
