The oviduct isthmus is capable of transporting spermatozoa and ova in opposite directions. A column of tenacious mucus that occupies the lumen of the rabbit oviduct isthmus during estrus may permit sperm transport. After ovulation the mucus disappears, with subsequent efforescence of cilia, which probably assist transport of ova to the uterus.
输卵管峡部能够向相反方向输送精子和卵子。发情期占据兔输卵管峡部管腔的一列黏性黏液可能有助于精子运输。排卵后,黏液消失,随后纤毛出现,这可能有助于将卵子输送到子宫。
