Distribution of cholinergic nerves in the oviduct wall in rabbits was investigated by a neurohistochemical method after El Badawi and Schenk. Higher density of cholinergic nerve fibres was confirmed to occur mainly in the isthmic part, but in contrast with literary data it was also found in the ampullar part of oviducts. In the basal parts of oviduct mucosa there were only few cholinergic nerve fibres unlike their density in a thick muscular tissue; this is probable to be related with its influence on oviduct motility. In the course of pregnancy, progesterone reduces the number of cholinergic nerves in rabbit oviducts, the number is largely reduced in test rabits; they indicate that the rabbit oviduct is not any ideal model to study the development of cholinergic innervation in dependence on oestrous cycle phase and pregnancy duration and that they should not be applied to changes in the functional neuromorphology of tuba uterina in woman.
