Comparative studies were made on different heterosexual groups of Microcebus murinus during the period of sexual activation, which is determined by the photoperiod. In pairs (1 male--1 female), the sexual activation of the males occurs during January. This is accompanied by a loss of body weight and by an increase in basal oxygen consumption. The testes are maximal in size by the beginning of March. In groups of 8 individuals (4 males--4 females) only one male exhibits normal sexual activity. He is the heaviest and mates with males. The 3 other males of the group show delayed activation and their testes are reduced in size. Two subordinate males died under the social pressure of severe diseases (e.g. renal failure) normally associated with overcrowding.
在由光周期决定的性激活期，对不同异性组的倭狐猴进行了比较研究。成对（1只雄性 - 1只雌性）饲养时，雄性的性激活发生在1月。这伴随着体重减轻和基础氧消耗增加。到3月初睾丸大小达到最大。在8只个体（4只雄性 - 4只雌性）的组中，只有一只雄性表现出正常的性活动。它是最重的，与雌性交配。该组的其他3只雄性表现出延迟激活，其睾丸尺寸减小。两只从属雄性在通常与过度拥挤相关的严重疾病（如肾衰竭）的社会压力下死亡。
