## Abstract The physiological role of gonadal androgens in regulating bone metabolism is not established. To determine if androgens antagonize the changes in cortical bone after gonadectomy, we treated orchiectomized (ORX) rats with testosterone (T) and 5Ξ±βdihydrotestosterone (DHT), and ovariectomi
## Abstract Exploration, measured by headβdipping in a holeboard, was tested in male rats at 16, 21, 28, 56, and 84 days of age. Headdipping increased with increasing age from Day 16 to Day 84, and so did the number of rears made. At all ages handled rats showed more headβdipping and made more rear
Gender differences in hepatic sex steroid and drug metabolism result from hormonal regulation of specific cytochrome P450 genes (CYP). In male rats, bile duct ligation (BDL) is associated with down-regulation of the male-specific genes, CYP2C11 and CYP3A2, together with a decrease in serum testoster
