本研究探讨了长期的父亲的存在（同居）的影响，如体重，肾上腺重量，皮质醇的父母，和生存的幼仔相比，简短的日常遭遇（隔离）的雄性-雌性对金黄仓鼠（Mesocricetus auratus）的生理参数。我们发现，女性受同居证明了增加的身体和肾上腺重量，皮质醇浓度升高，和更重的子宫和脾脏相比，同居男性和孤立的女性。此外，我们还发现侧腺的十四烷酸和十六烷酸具有性二态性，它们是假定的雌性信息素。这两种化合物在女性中被抑制，在男性中被同居升高，表明同居损害了性化学信号。总体而言，我们得出结论，在金仓鼠中，将雌性和雄性圈养在一起对成年仓鼠及其幼仔的生存产生了有害影响。
This study investigated the impact of long-term paternal presence (cohabitation) on several physiological parameters such as body weight, adrenal weight, cortisol of parents, and the survival of pups compared with brief daily encounters (isolation) of male–female pairs in golden hamsters (Mesocricetus auratus). We showed that females were affected more by cohabitation as evidenced by increased body and adrenal weights, elevated cortisol concentrations, and heavier uteri and spleens as compared with cohabiting male and isolated females. Furthermore, we found that tetradecanoic and hexadecanoic acids of the flank glands were sexually dimorphic, for which they were putative female pheromones. These two compounds were suppressed in females and elevated in males by cohabitation, suggesting that cohabitation impaired sex chemosignals. Overall, we concluded that housing females and males together had deleterious effects on adults and the survival of their pups in the golden hamster.
