Some foods have been researched to trigger the production of testosterone, including egg yolks and honey. This study aims to study the effect of egg yolks and honey on aggressive behavior of rats. This study is a pre-experimental study with pre-posttest design. Rats fed egg yolks were painted on their rat fur with red and black marks. Rats fed honey were painted in blue and yellow mark. Aggressive behavior is seen from cardboard, Styrofoam, and stalk damage. The behavior of aggressive interventions among rats was also observed. The results of this study indicate both egg and honey increase the aggressive behavior of rats. However, aggressive intervention among rats was shown in a group of rats fed egg yolks.
