The ability of urine from female mice to delay puberty in test females was directly related to the density and duration of grouping of females. When females were removed from group housing their urine lost its ability to delay puberty within 10 days. No interactive effects were observed between duration and density of grouping on the onset of pheromone release after grouping or on the persistence of pheromone release after re-isolation. Urine from grouped females lost its ability to delay puberty in test females after 7 days of exposure to air.
雌性小鼠尿液延迟受试雌性小鼠青春期的能力与雌性小鼠的群居密度和持续时间直接相关。当雌性小鼠从群居环境中移出时，其尿液在10天内就失去了延迟青春期的能力。在群居后信息素释放的开始时间或重新隔离后信息素释放的持续时间方面，未观察到群居持续时间和密度之间的交互作用。群居雌性小鼠的尿液在暴露于空气中7天后，失去了延迟受试雌性小鼠青春期的能力。
