Following ejaculation into the vagina, dog sperm remain functionally competent for many days, acquire the ability to fertilize, and are delivered to an appropriate site within the uterine tube synchronously with the appearance of fertile oocytes. The mechanisms involved in regulating this system are complex, and allow for sperm storage within the female reproductive tract. The aim of this paper is to review current knowledge of the transportation of sperm and their biology within the reproductive tract of the bitch.
射精进入阴道后，犬精子在数天内仍保持功能活性，获得受精能力，并在可育卵母细胞出现时同步输送至输卵管内的合适部位。调节该系统的机制很复杂，可使精子在雌性生殖道内储存。本文旨在综述目前关于母犬生殖道内精子运输及其生物学特性的知识。
