Clinical and pre-clinical findings point to the critical role of ovarian hormones in modulating anxiety and depressive symptoms in female. However, few studies investigated the effects of long-term ovarian hormones withdrawal on animal behavior. The current study evaluated the behavioral effects of long-term ovariectomy (performed at 3 months of life) in adult (6 months old) and aged (18 months old) rats subjected to the elevated plus-maze and forced swimming tests. A substantial reduction in the time spent in open arms in adult and aged ovariectomized rats was observed compared to intact animal from the same age. A significant increase in the immobility time was observed in aged rats, ovariectomized or not, compared to adult rats. It should be noted that no alterations in the spontaneous locomotion were detected among groups. In addition, a reduction in serum concentrations of 17beta-estradiol was observed in adult ovariectomized and aged sham and ovariectomized rats compared to adult intact animals. Taken together, these findings suggest that anxiety-related behaviors were affected by ovariectomy, but not aging. However, the depressive-like behavior observed in aged rats seems to be much more influenced by senescence than ovarian hormones withdrawal. The presented results are discussed considering the effects of gradual and abrupt reduction of ovarian steroids concentrations, and the influence of aging on behavior of female rats.
