“…To study the effect of a more profound sexual disorder, we next examined male rats subjected to castration. The fact that gonadectomy reduces circulating T levels and eliminates masculine mating behavior and that exogenous T treatment can restore or prevent this castration-induced decline in sexual behavior is well established (reviewed by Sachs & Meisel, 1988;Sodersten & Eneroth. 1983).…”

“…601-335; 3.4-mm inside diameter, 4.6-mm outside diameter; prepared according to the procedure of Legan, Coon, & Karsch, 1975). According to Sodersten and Eneroth (1983), T-filled capsules of this size generate stable plasma hormone liters that approximate the average androgen levels observed in the Wistar strain of rats used in this study. A third group of males (n = 10) were sham-operated (scrotal incision) while under Brietal anesthesia.…”

Male rats that had cohabited with ovariectomized females for 2 weeks became more aggressive toward male intruders after a novel estrous female had been placed in their home cages for a period of 4 hr on the previous day. No increase in aggression was seen in males exposed to anestrous females. Genital anesthesia did not attenuate the female-enhanced aggression effect. By contrast, no enhancement of aggression was observed in long-term castrated males after 24 hr of exposure to estrous females. Rats with bilateral electrolytic lesions in the medial preoptic area showed a normal female-enhanced aggression effect. The observations that exposure to females facilitates aggression in males subjected to genital anesthesia and in males with preoptic lesions raise the possibility that copulatory cues are not always required for the effect.
