MODIFICATION OF THE DIRECTION OF UTERINE CONTRACTIONS BY INTRA-UTERINE DEVICES IN THE EWE

in Reproduction

Summary.

The direction of uterine contractions in vivo was studied in oestrous ewes by recording the motility of exteriorized uteri on cine film. In eight control ewes, 58% of 1156 contractions moved towards the oviduct, while 16% moved towards the cervix. In eight ewes with a plastic spiral in the lumen of one horn, only 17% of 927 contractions moved towards the oviduct; 70% of the contractions moved towards the cervix. The effect of the IUD on the direction of uterine contractions may explain inhibition of sperm transport and ovum fertilization in `IUD' ewes.
