Abstract

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.
