title: A new method for continuous recording of oviductal pressure variations in unrestrained gilts.
abstract: A new method using two intraluminally placed ultra-miniature pressure sensors placed in the same isthmus of the oviduct has been developed for continuous monitoring of oviductal pressure variations during the oestrous cycle in unrestrained gilts. Each test animal was followed for 48 h during which recordings were made at frequent intervals. By using two points of registration, directions of pressure waves could be determined. This technique allows for the determination of the base pressure in the oviduct and how it varies during the oestrous cycle. Effects of different stimuli and the effect of narcosis on oviductal activity can also be directly studied.
