Animal Group	Testosterone (ng/ml)	DHT (pg/ml)	17β-Estradiol (pg/ml)	Body Weight (g)
Intact Male	2.2±0.2*	476±45*	27±4*	287±4
ORX	ND	49±5	8±1	292±3
ORX+T	3.3±0.4*	214±15*	6±1	317±2*
ORX+DHT	ND	288±24*	7±1	311±4*

Values represent means ± SEM; ORX, orchiectomized; T, testosterone, DHT, dihydrotestosterone; E, 17β-estradiol; ND, not detectable;
