The oviducts of 24 mares were examined to determine the site of retention of unfertilized eggs. The ampullary-isthmic junction regions of 42 of the 48 oviducts were serially sectioned and examined histologically. The remaining parts of the oviducts were flushed and the flushings searched microscopically. Of 45 eggs located, 40 were in the sectioned segments of 24 oviducts and only 5 were in the flushings. All but one of the sectioned segments contained prominent masses of material obstructing the lumen, but these were apparently not the direct cause of egg retention since eggs were found on both sides of them.
对24匹母马的输卵管进行了检查，以确定未受精卵的滞留部位。48条输卵管中的42条的壶腹-峡部连接区域被连续切片并进行组织学检查。对输卵管的其余部分进行冲洗，并对冲洗液进行显微镜检查。在找到的45枚卵子中，40枚位于24条输卵管的切片段中，只有5枚在冲洗液中。除了一个切片段外，所有切片段都有突出的物质团块阻塞管腔，但这些显然不是卵子滞留的直接原因，因为在它们两侧都发现了卵子。
