Assessment of endocervical and endometrial damage inflicted by embryo transfer trial: a hysteroscopic evaluation

Abstract

The aim was to assess the endocervical and endometrial damage inflicted by embryo transfer trial using office hysteroscopy. Seventy-five consecutive infertile women who underwent office hysteroscopy were enrolled. Hysteroscopy was performed immediately after embryo transfer trial. The relationship between clinical perception of easiness of transfer, presence of blood on the catheter, degree of endocervical and endometrial damage was examined. In the difficult transfer group, minor and moderate endocervical lesions were noted in 35% and 24% of the cases, respectively. The respective figures for the easy transfer group were 19% and 3% (P>.05). There was a statistically significant concordance between the perceived difficulty of transfer and degree of endometrial damage (P<0.05). Of interest, in the easy transfer group, 32% of the patients had minor, 3% moderate and 65% no endometrial damage. The respective figures were 42%, 29% and 29% in the difficult transfer group. There was blood on the catheter in 25%, 56% and 71% of the easy, moderate and difficult transfer groups, respectively. There was a statistically significant concordance between the perceived difficulty of embryo transfer and presence of blood on the catheter (P<0.05). These results suggest that clinical perception of difficulty of transfer and the presence of blood on the catheter are directly associated with endometrial disruption.
