Reviewer's report:
The authors tried to answer the effect of chronic endometritis on the outcome of IVF treatment and
pregnancy rate-live births.
They conducted a well organized methodology and wrote the study in a comprehensive manner.
I think this is a valuable study and reach a high scientific priority in the field of reproduction.
