With the aid of x-ray ventriculography, lesions were placed in the medial preoptic-anterior hypothalamic (MP-AH) area of 5 adult male pygmy goats. The lesions resulted in a marked decrement in ejaculatory responses, as they have in previous studies on rats, cats, dogs and rhesus monkeys. The results illustrate the apparent universal effects of MP-AH lesions on copulatory behavior in mammalian species. Male sex-typical non-courtship responses of flehmen, self-enurination and penis licking were not altered by the MP-AH lesions. Since the non-courtship responses are displayed most frequently when male goats are sexually aroused, the results point to a specific effect of the lesions in disturbing a male's copulating performance while sparing other expressions of sexual arousal.
借助X射线脑室造影术，在5只成年雄性侏儒山羊的内侧视前区-下丘脑前部（MP-AH）区域制造损伤。与之前对大鼠、猫、狗和恒河猴的研究结果一样，这些损伤导致射精反应显著减少。结果表明，MP-AH损伤对哺乳动物的交配行为具有明显的普遍影响。MP-AH损伤并未改变雄性特有的非求偶反应，如卷唇嗅反应、自尿症和舔阴茎行为。由于雄性山羊在性唤起时最常表现出非求偶反应，这些结果表明损伤具有特定作用，即干扰雄性的交配表现，同时不影响其他性唤起表现。
