通过实验确定了保加利亚仓鼠（Phodopus campbelli）在性识别和生殖状态交流中所涉及的所有气味。通过研究男性对女性气味的偏好，研究人员发现，一些气味支持女性在生殖状态下的偏好，另一些气味只在发情期引起偏好，还有一些气味不会引起性偏好。同样，女性对男性气味的偏好也仅限于某些气味。研究人员还测试了不同生殖状态（发情期、产前、产后发情期）男性对女性气味的偏好。四种不同的气味在不同的生殖状态下具有不同的吸引力，并且有三种不同的变化模式：(1)口腔和尿液气味仅在产后发情期间具有吸引力；(2)产前1天中腹腺最具吸引力；(3)阴道分泌物呈现吸引力分级模式，在产后发情期达到高峰。这些结果表明，不同的气味提供了一些冗余和不同的信息，他们表明，跨气味代码可以用来提供关于雌性生殖状态的非常精确的信息。(C) 1996学术出版社，Inc.
Experiments were conducted to determine the repertoire of odors that are involved in sexual recognition and communication about reproductive state in Djungarian hamsters (Phodopus campbelli). By examining the preferences of males for odors of females over those of males, it was found that some odors support preferences across female reproductive states, other odors induce preferences only during estrus, and yet other odors do not elicit sexual preferences. Similarly, female preferences for male odors was restricted to just some scents. Males were also tested for their preferences for female odors from different reproductive states (diestrous, day before parturition, post-partum estrus). Four different odors were found to vary in attractiveness with these reproductive states, and there were three different patterns of change: (1) mouth and urine odors were attractive just during post-partum estrous; (2) midventral gland was most attractive the day before parturition; (3) vaginal secretions showed a graded pattern of attractiveness, peaking at post-partum estrus. These results show that different odors provide some redundant and some different information, and they suggest that an across-odor code could be used to provide very precise information about a female's reproductive state.
