The effect of two different conditions of humidity (80 +/- 5% and 40 +/- 5%) under stimulatory photoperiod (14L/10D) and high temperature (38 +/- 2 degrees C) was studied on the testes and accessory sex organs of the Indian palm squirrel, Funambulus pennanti, during the sexually active phase. High humidity (80 +/- 5%) reduced significantly the testes weight of the sham-operated animals as compared to the controls under natural environmental conditions but had no effect on that of pinealectomized animals. Moderate humidity (40 +/- 5%) did not affect the testes of sham-operated as well as pinealectomized animals, as compared to the respective controls. The seminal and prostatic weights showed no significant difference in high or moderate humidity conditions. However, the epididymal weight of the animals exposed to high humidity was significantly reduced in sham-operated animals only. Thus, these results indicate that the pineal gland may be implicated in mediating the humidity information to control the male gonadal function in the Indian palm squirrel, Funambulus pennanti.
在性活跃期，研究了刺激性光周期（14小时光照/10小时黑暗）和高温（38±2摄氏度）条件下，两种不同湿度条件（80±5%和40±5%）对印度棕榈松鼠（Funambulus pennanti）睾丸和附属生殖器官的影响。与自然环境条件下的对照组相比，高湿度（80±5%）显著降低了假手术动物的睾丸重量，但对松果体切除动物的睾丸重量没有影响。与各自的对照组相比，中等湿度（40±5%）对假手术动物和松果体切除动物的睾丸均无影响。在高湿度或中等湿度条件下，精囊和前列腺重量没有显著差异。然而，仅在假手术动物中，暴露于高湿度环境下的动物附睾重量显著降低。因此，这些结果表明，松果体可能参与介导湿度信息，以控制印度棕榈松鼠（Funambulus pennanti）的雄性性腺功能。
