Abstract：Objective To evaluate the correlation between blood staining on the embryo transfer catheter and the outcome in fresh IVF/ICSI cycles .Methods Retrospective analysis was performed on the data about patients who under-went fresh long protocol IVF/ICSI cycle in a single IVF center .The cycles were grouped into three according to a semi-quantitative system for recording the amount of blood on the transfer catheter .The demographic data , implantation rate , and clinical pregnancy rate were noted and compared .Results A total of 2 601 cycles were examined , among which 1 754 cycles were without blood staining on the catheter during ET , while the other 847 cycles were associated with blood staining.The implantation rate (IR) and clinical pregnancy rate (CPR) in the group without blood staining were signifi-cantly higher than the group with blood staining ( 34.8% vs 30.7%, P=0.002; and 54.1% vs 47.6%, P value =0.013).However, there was no significant difference was found in IR or CPR among different groups of bloody staining degree.Conclusion Blood staining on the embryo transfer catheter may reduce the embryo implantation and clinical pregnancy rate.However, the degree of bloody staining may not worsen the clinical outcome .
