The objectives of this work were to describe some morphometric characteristics and to establish quantitative parameters of different regions of the equine oviductal mucosa from the isthmus, ampullary-isthmic junction (AIJ), and ampulla. Twenty-one mixed-bred mares were used for this study. Mares were selected in the following reproductive phases: anestrus, estrus, and diestrus. The left oviducts were examined with light microscopy, and rights ones were studied through the intraoviductal molds. The isthmus showed the smallest luminal area, mucosal area, epithelial perimeter, and luminal diameter. On the molds surfaces, some grooves extended as longitudinal canals, reducing their depth as they approached to the AIJ. Several small height projections, some obliquely positioned towards utero-tubal junction, were observed in all reproductive phases. These formations may represent pockets or cul-de-sacs in the basal areas of the epithelial folds. The AIJ mucosa gradually changed from the smooth isthmic region toward highly folded ampulla. The number and complexity of epithelial folds showed moderate increase in the same way that many of the morphometric parameters. Multiple curves were observed on the molds of the AIJ, creating a zigzag path in the oviductal lumen. In the ampulla, the high branched epithelial folds occupied most of the lumen, leaving a small luminal area free. A linear relationship between epithelial perimeter and mucosal area was found. The presence of glandular-like structures was observed in all the reproductive stages studied. The equine endosalpinx reveals a highly complex tridimensional arrangement where each region shows very particular and specific designs.
本研究的目的是描述马输卵管黏膜不同区域（峡部、壶腹 - 峡部连接处和壶腹部）的一些形态计量学特征并建立定量参数。本研究使用了21匹杂种母马。母马被选在以下生殖阶段：乏情期、发情期和间情期。左侧输卵管用光学显微镜检查，右侧输卵管通过输卵管内铸型进行研究。峡部的管腔面积、黏膜面积、上皮周长和管腔直径最小。在铸型表面，一些凹槽呈纵向管道延伸，靠近壶腹 - 峡部连接处时深度减小。在所有生殖阶段均观察到一些小的高度突起，有些向子宫 - 输卵管连接处倾斜。这些结构可能代表上皮皱襞基部区域的袋状或盲端。壶腹 - 峡部连接处的黏膜从光滑的峡部区域逐渐变为高度折叠的壶腹部。上皮皱襞的数量和复杂性与许多形态计量学参数一样适度增加。在壶腹 - 峡部连接处的铸型上观察到多条曲线，在输卵管腔内形成锯齿状路径。在壶腹部，高度分支的上皮皱襞占据了大部分管腔，仅留下小部分管腔空间。发现上皮周长与黏膜面积之间存在线性关系。在所研究的所有生殖阶段均观察到腺样结构的存在。马输卵管内膜呈现高度复杂的三维排列，每个区域都显示出非常独特和特定的设计。
