通过两个实验评估了雌性小鼠（SJL/J）尿液线索对雄性泌尿生殖器官嗅探、攻击和骑乘行为的调节。实验1检验了切除卵巢和完整卵巢雌性的尿液在调节有性经验和没有性经验的雄性对对照物质水的行为方面的功效。研究发现，切除卵巢的雌性小鼠的尿液没有表现出行为调节特性，而完整雌性小鼠的尿液在雄性小鼠中减少了攻击行为，但增加了嗅探和骑乘行为。这些发现表明卵巢依赖的化学信号只包含在完整的雌性尿液中。先前的性经验对男性接触卵巢切除的女性的尿液时的行为没有影响。然而，当性经验丰富的雄性接触完整雌性的尿液时，嗅和骑的行为增加了。实验2使用性经验不足的雄性，评估了四个发情期雌性尿液的化学信号活性。结果表明，发情期和发情期雌性的尿液增加了嗅探和骑乘行为，减少了攻击行为。母羊的尿液只具有诱导嗅觉和减少量的化学信号特性。雌性发情期的尿液缺乏攻击和数量调节的化学物质，但可能具有诱导嗅觉的化学信号。
Modulation of male urogenital sniff, attack, and mount behaviors by urinary cues from female mice (SJL/J) was assessed in two experiments. Experiment 1 examined the efficacy of urine from ovariectomized and intact females in modulating the behavior of sexually experienced and inexperienced males vis-a-vis the control substance, water. It was found that urine from ovariectomized females showed no behavior-modulating properties, whereas urine from intact females decreased attack but increased sniff and mount behaviors in male mice. These findings are indicative of ovarian-dependent chemosignals contained in the urine of only intact females. Prior sexual experience had no effect on behavior of males when exposed to urine from ovariectomized females. Sniff and mount behaviors were, however, increased when sexually experienced males were exposed to urine from intact females. Using sexually inexperienced males, Experiment 2 assessed the chemosignal activity of urine from females in each of four estrous phases. It was determined that urine from proestrous and estrous females increased sniff and mount behaviors and decreased attack behavior. Urine from metaestrous females was shown to possess only sniff-inducing and mount-reducing chemosignal properties. Urine from females in diestrous lacked attack- and mount-modulating chemocues but may possess a sniff-inducing chemosignal.
