Twenty-four adult male rats with previous sexual experience were tested for aggression against intruders after one of four treatments (n = 6 per treatment): exposure to inaccessible estrous females; exposure to anestrous females; no female exposure, or copulation to ejaculation. Although both exposure to inaccessible estrous females and copulation significantly decreased latency to attack only copulation produced significant elevation of intensity and duration of attack. Results are discussed in reference to the role of aggression in maintaining priority of access to females, and as a means of assuring paternity of offspring by dominant males.
对24只具有性经验的成年雄性大鼠进行如下四种处理之一（每种处理n = 6）后，测试它们对入侵者的攻击性：接触无法接近的发情期雌性；接触非发情期雌性；不接触雌性；或交配至射精。虽然接触无法接近的发情期雌性和交配都显著缩短了攻击潜伏期，但只有交配显著提高了攻击强度和持续时间。结合攻击行为在维持接近雌性的优先权方面的作用以及作为优势雄性确保后代父权的一种手段，对结果进行了讨论。
