The "utero-vaginal junction" that connects the uterus and vagina of duck oviduct differs histologically and histochemically from the adjacent zones. The region is characterised by low, somewhat longitudinally arranged mucosal folds, lined by tall columner cilliated cells with apical nuclei alternating with mucous secreting goblet cells containing basal nuclei. Within the propria of the mucosa there are numerous tubular glands--the sperm host glands--which are responsible for sperm storage after copulation. The goblet cells of the utero-vaginal junction contain an admixture of neutral, sulfated and nonsulfated acid mucopolysaccharides, while the sperm host glands are devoid of any mucopolysaccharide and secrete complex lipoidal materials and exhibit intense acid phosphatase activity. The functional significance of the secretory materials of the sperm host glands have been discussed in the light of sperm release mechanism.
连接鸭输卵管子宫和阴道的“子宫 - 阴道交界处”在组织学和组织化学上与相邻区域不同。该区域的特征是黏膜皱襞较低，呈 somewhat 纵向排列，由高柱状纤毛细胞衬里，顶端细胞核交替出现，与含有基底细胞核的黏液分泌杯状细胞相邻。在黏膜固有层内有许多管状腺体——精子储存腺——负责交配后精子的储存。子宫 - 阴道交界处的杯状细胞含有中性、硫酸化和非硫酸化酸性粘多糖的混合物，而精子储存腺不含任何粘多糖，分泌复杂的类脂物质并表现出强烈的酸性磷酸酶活性。根据精子释放机制讨论了精子储存腺分泌物质的功能意义。 （注：原文中“somewhat”疑有误，可能是“somewhat”，意为“有点，稍微” ，翻译时保留了原文错误单词，未擅自修改）
