The histological effect on the felid uterus of sterilization, via ovariectomy or salpingectomy, is currently unknown. To investigate the association of ovariectomy or salpingectomy with uterine health, it is first necessary to establish if changes are distributed evenly throughout the uterus. Both laparoscopic ovariectomy and salpingectomy with concurrent sampling of the tip of the uterine horn are possible in the cheetah. Currently accepted practice for histopathological screening of the uterus utilizes four biopsy samples. It is not known whether this method accurately reflects the status of the entire uterus. In this study we histologically examined the uteri of six older cheetahs (one 7-year-old and five 10-10.5-year-old animals) via 21 tissue samples (three samples from seven different anatomical regions) per cheetah to determine overall uterine health. Although no defined lesions were detected, mild endometrial gland dilation, assumed to be of no functional consequence, was observed in multiple samples. The odds of observing this dilation was lowest in the uterine body and progressively increased in a cranial direction, being significantly higher at the tip of the uterine horns (OR = 11.5; 95% CI, 2.0-65.1; p = 0.006). This supported the reliability of sampling the tip of the uterine horn to screen for endometrial gland dilation.

老年圈养猎豹（Acinonyx jubatus）子宫组织学变化的分布
目前尚不清楚通过卵巢切除术或输卵管切除术对猫科动物子宫进行绝育的组织学效果。为了研究卵巢切除术或输卵管切除术与子宫健康的关系，首先需要确定变化是否均匀分布在整个子宫。在猎豹中，腹腔镜卵巢切除术和输卵管切除术都可以同时对子宫角尖端进行取样。目前接受的子宫组织病理学筛查实践使用四个活检样本。这种方法是否能准确反映整个子宫的状态，尚不得而知。在这项研究中，我们对六只年长猎豹（一只 7 岁，五只 10-10 岁）的子宫进行了组织学检查。5 岁动物）通过每只猎豹 21 个组织样本（来自七个不同解剖区域的三个样本）来确定整体子宫健康。虽然没有检测到明确的病变，但在多个样本中观察到轻微的子宫内膜腺扩张，假定没有功能后果。观察到这种扩张的几率在子宫体中最低，并在头颅方向逐渐增加，在子宫角尖端显着更高（OR = 11.5；95% CI，2.0-65.1；p = 0.006）。这支持了对子宫角尖端取样以筛查子宫内膜腺扩张的可靠性。观察到这种扩张的几率在子宫体中最低，并在头颅方向逐渐增加，在子宫角尖端显着更高（OR = 11.5；95% CI，2.0-65.1；p = 0.006）。这支持了对子宫角尖端取样以筛查子宫内膜腺扩张的可靠性。观察到这种扩张的几率在子宫体中最低，并在头颅方向逐渐增加，在子宫角尖端显着更高（OR = 11.5；95% CI，2.0-65.1；p = 0.006）。这支持了对子宫角尖端取样以筛查子宫内膜腺扩张的可靠性。
