THE EFFECT OF AN INTRA-UTERINE SUTURE ON FERTILITY IN THE RAT

Abstract
A nylon suture inserted into one uterine horn prevented implantation in the same horn in 60.7% of rats. In the remainder which showed implantations in the treated horn, the number of implantation sites was significantly lower than in control horns. Some of these embryos were underdeveloped or dying. Histologically it could be shown that in some rats implantations occur even if the suture passes through the lumen of the horn. The leucocytic infiltration of the endometrium was associated with prevention of implantation, but it occurred, albeit to a lesser extent, also in rats with implantations in treated horns.
