Exposure of male Syrian hamsters (Mesocricetus auratus) for 10 weeks to short photoperiod (SP) providing 10 hr light: 14 hr darkness (10:14 LD) produced a significant reduction in the weights of the reproductive organs, plasma thyroxine (T4) levels and free T4 index (FT4I) compared to the values of animals exposed to long photoperiod (LP, 14:10 LD). C57bl male house mice (Mus musculus) kept in SP (10:14 LD) had reproductive organ weights equivalent to those of mice kept in long days (14:10 LD) and lower T3 uptake (T3U) values. Male gerbils (Meriones unguiculatus) exposed to 13 weeks of SP (10:14 LD) had lower body weights, testes and seminal vesicle weights and higher T3U values compared to LP (14:10 LD) controls. However, no effect was seen on plasma T4 and triiodothyronine (T3) values nor the FT4I and free T3 index (FT3I). White-footed male mice (Peromyscus leucopus) exposed to SP (8:16 LD) had significantly lower testes and seminal vesicle weights while plasma T4 and T3 levels were unaffected. Snell strain house mice (Mus musculus) exposed to SP (8:16 LD) had normal reproductive organ weights compared to the values of LP-exposed (16:8 LD) control animals. However, there was a significant depression in T3 and in the FT3I in the SP animals.
将雄性叙利亚仓鼠（金仓鼠）暴露于短光照周期（SP）10周，光照时长为10小时：黑暗时长为14小时（10:14 LD），与暴露于长光照周期（LP，14:10 LD）的动物相比，其生殖器官重量、血浆甲状腺素（T4）水平和游离T4指数（FT4I）显著降低。饲养在SP（10:14 LD）条件下的C57bl雄性家鼠（小家鼠），其生殖器官重量与饲养在长日照（14:10 LD）条件下的小鼠相当，但T3摄取量（T3U）值较低。与LP（14:10 LD）对照组相比，暴露于13周SP（10:14 LD）的雄性沙鼠（长爪沙鼠）体重、睾丸和精囊重量较低，T3U值较高。然而，血浆T4和三碘甲状腺原氨酸（T3）值以及FT4I和游离T3指数（FT3I）均未受影响。暴露于SP（8:16 LD）的白足雄性小鼠（白足鼠）睾丸和精囊重量显著降低，而血浆T4和T3水平未受影响。与暴露于LP（16:8 LD）的对照动物相比，暴露于SP（8:16 LD）的斯内尔品系家鼠（小家鼠）生殖器官重量正常。然而，SP组动物的T3和FT3I显著降低。
