Contrary to the prevalent view, there seems to be no competition in the mammalian female genital tract among large numbers of sperm cells that are racing towards the egg. Instead, small numbers of the ejaculated sperm cells enter the Fallopian tube, and these few must be guided to make the remaining long, obstructed way to the egg. Here, we review the mechanisms by which mammalian sperm cells are guided to the egg.
与普遍观点相反，在哺乳动物的雌性生殖道中，大量精子向卵子游动的过程中似乎不存在竞争。相反，只有少量射出的精子进入输卵管，而这少数精子必须得到引导，才能走完剩下漫长且充满阻碍的通往卵子的路程。在此，我们综述哺乳动物精子被引导至卵子的机制。
