Abstract

Electrolytic lesions were placed in the hypothalamus of 20 sexually vigorous, male guinea pigs. They did not produce uniform effects on all components of sexual behavior in the individual animals. Extensive lesions located between the nucleus filiformis magnocellularis and the premammillary nucleus produced immediate and almost complete and sustained loss of sexual behavior. The behavior was not restored by administration of testosterone propionate. It was concluded that the hypothalamus as a neural mechanism is essential to the performance of certain components of the sexual behavior pattern quite independently of the pituitary-gonadal axis.
