Normal cock (with both testes removed): had small combs and wattles, no interest in hens, a weak crow, and listless ﬁght behavior B. Castrated Cock (with one testes replaced): experienced normal comb and wattles, an interest in hens, a normal crow, and aggressive ﬁght behavior C. Conclusion: Testosterone is responsible for male physical characteristics, calling, mating, and running. II. Six Categories of Chemicals in Animals A.
