This study was carried out to investigate the effect of the male hormone testosterone (T) on weight and blood picture of male rabbits. Fifteen (15) adult male rabbits were weighed and divided into 3 groups: a control group (received 100 μl of sesame oil), a low dose group (received 6 mg T/ kg b. w.), and a high dose group (received 12 mg/kg b. w.). The rabbits were injected intramuscularly once a week for 6 weeks. After the end of the injection period, the rabbits were weighed, slaughtered and blood samples collected for analysis. Injection of T caused significant increases in the levels of T and growth hormone in the sera of treated animals. The hormone also caused significant increases in the weights of treated rabbits. The red blood corpuscles count, the hemoglobin concentration, the percent hematocrit and the platelets count were found to significantly increase with the injection of T. The hormone had no significant effect on the mean corpuscular volume, the mean corpuscular hemoglobin, the mean corpuscular hemoglobin concentration and white blood cells. It is concluded that the increases in red blood corpuscles could have a significant effect on the viscosity of the blood, which could also have an effect on the heart function.
