The blood supply to the tubal corner of the uterus may originate from the uterine and ovarian arteries. The border of supply from the arteries has been found to move in young women; the change seemed dependent on ovarian steroid production. The present work investigated whether the border of supply could differ between the two sides of the uterus in the same woman having one dominant follicle (>10 mm).
Vagina was flushed with saline of room temperature in 15 women with a dominant follicle >10 mm. The temperature was measured in the mid-uterine lumen and in the tubal corner of the uterus at 2, 5 and 7 min after starting cooling. The investigation was repeated 30 min later measuring the temperature in the other tubal corner.
The temperature decrease was, as found in previous investigations, more pronounced in the uterine cavity than in the tubal corners. However, a difference was found between the two tubal corners. At all measurement times the decrease was significantly smaller in the tubal corner corresponding to the dominant follicle than in the contralateral side.
In our model, 'cold' is transferred from the vaginal venous blood to the uterine artery and the cooling defines the supply area of the uterine artery. Therefore, the results indicate that the area of supply from the ovarian artery in the tubal corner ipsilateral to the dominant follicle is greater than that in the contralateral side. It is possible to speculate that this difference is related to the hormonal production of the dominant follicle.
子宫输卵管角的血液供应可能源自子宫动脉和卵巢动脉。已发现年轻女性中动脉供血边界会发生移动；这种变化似乎取决于卵巢甾体激素的分泌。本研究调查了在同一侧有一个优势卵泡（>10毫米）的女性中，子宫两侧的供血边界是否存在差异。
对15名有优势卵泡>10毫米的女性，用室温生理盐水冲洗阴道。在开始降温后2分钟、5分钟和7分钟，测量子宫腔中部和子宫输卵管角的温度。30分钟后重复该调查，测量另一侧输卵管角的温度。
正如先前研究所发现的，子宫腔内的温度下降比输卵管角更明显。然而，两个输卵管角之间存在差异。在所有测量时间，与优势卵泡相对应的输卵管角的温度下降明显小于对侧。
在我们的模型中，“冷”从阴道静脉血传递到子宫动脉，降温确定了子宫动脉的供血区域。因此，结果表明优势卵泡同侧输卵管角的卵巢动脉供血区域大于对侧。可以推测这种差异与优势卵泡的激素分泌有关。
