Reviewer's report:
I read with great interest the manuscript, which falls within the aim of this Journal. In my honest opinion,
the topic is interesting enough to attract the readers' attention. Nevertheless, authors should clarify some
points and improve the discussion, as suggested below.
Authors should consider the following recommendations:
- Manuscript should be further revised in order to correct some typos and improve style.
- I would suggest to stress novel pieces of evidence about chronic endometritis, including the impaired
inflammatory state of the endometrium (IISE), referring to: PMID: 31710184: PMID: 32802019.
