在未交配的雌性黄胃母鼠中，早在20日龄时就观察到子宫重量增加，表明生殖活动。与不熟悉的成年男性接触1小时或更少，48小时内，子宫重量增加至少持续10天。使用男性尿液引起的子宫重量增加与女性暴露于男性额外的视觉、听觉和嗅觉刺激时所观察到的相同；阉割雄性的尿液比未阉割雄性的尿液效果更差。直接身体接触完整的男性或他们的尿液是生殖激活的必要条件，视觉或空气传播的线索是不够的。这种物种的兄弟姐妹雄性-雌性通常不会繁殖，可能是因为雌性没有繁殖能力。将兄弟姐妹的雄性尿液涂在雌性的上唇上可以诱导发情和随后的繁殖，这表明兄弟姐妹之间的繁殖存在行为障碍。
In virgin female M. ochrogaster, increases in uterine weight, indicative of reproductive activation, were observed as early as 20 days of age. Exposure to an unfamiliar adult male for 1 h or less induced, within 48 h, increases in uterine weight lasting for at least 10 days. Applications of male urine induced increases in uterine weight equivalent to those observed in females exposed to additional visual, auditory and olfactory stimuli from the male; urine from castrated males was less effective than urine from intact males. Direct physical contact with intact males or their urine was essential to reproductive activation, and visual or air-borne cues were not adequate. Sibling male-female pairs of this species do not ordinarily reproduce, probably due to the failure of the female to become reproductively active. Estrus and subsequent reproduction were induced by applications of sibling male urine to the female''s upper lip, suggesting a behavioral barrier to reproduction among siblings.
