The possible role of the ovaries in hibernation was examined by comparing patterns of hibernation in intact and ovariectomized Turkish hamsters (Mesocricetus brandti). Ovariectomy had little, if any, effect on hibernation in these studies. However, females which were anovulatory prior to cold exposure entered hibernation more rapidly as compared to cycling females. Most females (both intact and ovariectomized) maintained in short days returned to a second phase of hibernation several months after terminating the initial phase. In contrast, most females housed in long days failed to show a second phase of hibernation. Thus, it is possible that effects of day length may be more important than effects of ovarian hormones in regulating hibernation in the female Turkish hamster.
通过比较完整的和卵巢切除的土耳其仓鼠（布氏中仓鼠）的冬眠模式，研究了卵巢在冬眠中的可能作用。在这些研究中，卵巢切除对冬眠几乎没有影响（如果有影响的话）。然而，与处于发情周期的雌性相比，在寒冷暴露前无排卵的雌性进入冬眠的速度更快。大多数饲养在短日照条件下的雌性（包括完整的和卵巢切除的）在初始冬眠阶段结束几个月后会进入第二个冬眠阶段。相比之下，大多数饲养在长日照条件下的雌性没有表现出第二个冬眠阶段。因此，在调节雌性土耳其仓鼠的冬眠方面，日照长度的影响可能比卵巢激素的影响更重要。
