Evidence suggests the existence of genetic differences in cocaine sensitization in male rats. The present study was undertaken to investigate cocaine sensitization in female rats of genetically distinct inbred (Fischer 344 and Lewis) and outbred (Sprague-Dawley) strains. All female rats were bilaterally ovariectomized and randomly assigned to one of four experimental groups: 1) estradiol benzoate group, 2) progesterone group, 3) estradiol benzoate-plus-progesterone group, and 4) ovariectomized group. Additional controls included sham-operated female rats, female rats that received a single oil injection, and female rats that received repeated oil injections. To determine gender-related differences in the acute and chronic effects of cocaine, data obtained from female rats were compared with those from strain- and weight-matched male rats. Estradiol benzoate-plus-progesterone female rats showed greater locomotor effect in response to an acute dose of cocaine and had more robust sensitization in response to repeated cocaine than did male rats. The bilateral removal of ovaries abolished cocaine sensitization. In all strains of rats studied, progesterone alone did not alter the ovariectomy-induced attenuation of cocaine behavior, but estrogen alone restored cocaine-induced behavioral sensitization. There were significant strain effects on the degree of gonadal hormonal-induced modulation of cocaine sensitization in female rats. Female Lewis rats were extremely sensitive to repeated-cocaine effects, whereas the Fischer 344 female rats showed only marginal effects. The Sprague-Dawley rats ranked intermediate in their behavioral sensitivity. The present study strongly supports the hypothesis that female rats are more sensitive to both acute and chronic behavioral effects of cocaine than are male rats and that the effects are strain dependent. It also shows that estrogen plays an important role in the increased sensitivity of female rats to cocaine sensitization. Together, these data indicate significant interactions between ovarian steroid hormones and genetic factors in cocaine-induced behavioral effects.
