Testosterone is known to be capable of rescuing of male copulatory behavior in gonadectomized males, but fails to cause this behavior in gonadectomized females. This thesis seeks to analyze the activational effects of testosterone on its receptor, the androgen receptor, in the medial preoptic area (MPOA) of male and female Syrian hamsters. Both the total expression and subcellular localization levels were analyzed to measure for differences in the amount and activity of the AR respectively. While the results have yet to be verified through sufficient replication for statistical analysis, results thus far indicate that there is a sex difference in expression and localization of AR.
