| 摘 要： | 黄毛鼠（Ｒａｔｔｕｓ ｒａｔｔｉｄｅｓ）在群居（４只／笼）时体重及性器官，如睾丸和附睾的增长都受到了极大的抑制；血清中睾酮含量的迅速上升以及成熟精子在附睾的曲细精管中出现的时间也比单独关养的晚。成年雄鼠的笼填充物的气味能够诱导幼年雄鼠体重，睾丸的总量和长度以及血清中睾酮的含量的增加。

| Abstract: | Group housing young male Rattus rattoides greatly suppressed physical growth and the growth of sexual organs such a. testes and epididymes. Pre-mature increase of plasma testosterone level observed in singly caged males, and the appearance of mature sperm in convoluted ducts of epididymes were delayed by group-housing. Adult-male soiled bedding contained pheromones. which accelerated the growth of body weight and testis length, and induced a trend of acceleration in testis weight and of a higher plasma testosterone, compared to the controls. |
