A reservoir of sperm in the initial segment of the oviduct has been found in several species of domestic and laboratory mammals. Evidently, the reservoir serves to ensure successful fertilization by providing the appropriate number of sperm in the appropriate physiological state for fertilizing oocytes soon after they enter the oviduct. Recent evidence indicates that sperm are trapped in the reservoir by binding to specific carbohydrate moieties on the surface of the mucosal epithelium of the oviduct. A bovine seminal plasma protein has been identified that associates with sperm and confers on them the capacity to bind to the carbohydrate moiety.
在几种家养和实验用哺乳动物中，已发现输卵管起始段存在精子储存库。显然，该储存库通过在卵母细胞进入输卵管后不久，提供处于适当生理状态的适量精子，来确保受精成功。最近的证据表明，精子通过与输卵管黏膜上皮表面的特定碳水化合物部分结合而被困在储存库中。已鉴定出一种牛精浆蛋白，它与精子结合并赋予精子与碳水化合物部分结合的能力。
