Chronic endometritis is associated with implantation failure and repeated miscarriages, and antimicrobial therapy has been shown to be effective. We experienced a case of successful conception after intrauterine lavage for residual menstrual blood and chronic endometritis. The patient was a 36-year-old woman who had undergone radical trachelectomy for stage IB1 cervical cancer at 26 years old and delivered a live infant 2 years later but had subsequently suffered repeated miscarriages and secondary infertility. One pregnancy was achieved through five cycles of intrauterine insemination (IUI), but it ended in miscarriage. Given that we detected residual menstrual blood due to cervical stenosis, and hysteroscopy and an endometrial biopsy revealed chronic endometritis, implantation failure due to deterioration of the intrauterine environment was suspected. Prior to IUI, intrauterine lavage was performed in the follicular phase, which resulted in two consecutive successful conceptions: the first miscarried at 6 weeks, and the second resulted in a stillbirth due to premature rupture of the membranes at 16 weeks. Uterine lavage may improve the intrauterine environment by physically removing residual menstrual blood and inflammatory mediators, thereby improving conception rates.}, pages = {4--9}, title = {月経血貯留および慢性子宮内膜炎に対する子宮内洗浄を行い妊娠成立し得た一例}, volume = {11}, year = {2022} }
