ABSTRACT
OBJECTIVE: A significant cause of infertility is the inability of the embryo to implant. Endometritis is one of the major causes affecting embryo implantation. The present study addressed the diagnosis and effects of chronic endometritis (CE) treatment on pregnancy rates after in vitro fertilization (IVF). PATIENTS AND METHODS: We conducted this retrospective study on 578 infertile couples treated with IVF. In 446 couples, we performed a control hysteroscopy with biopsy before IVF. In addition, we examined the visual aspects of the hysteroscopy and the results of the endometrial biopsies, followed by antibiotic therapy if necessary. Finally, the results of IVF were compared. RESULTS: Of the 446 cases studied, we diagnosed 192 (43%) with chronic endometritis, either by direct observation or based on the histopathological result. In addition, the cases diagnosed with CE we treated with a combination of antibiotics. The group diagnosed at CE and subsequently treated with antibiotic therapy had a significantly higher pregnancy rate after IVF (43.2%) than the group without treatment (27.3%). CONCLUSIONS: Hysteroscopic examination of the uterine cavity was particularly important for the success of IVF. The initial CE diagnosis and treatment were an advantage for the cases in which we performed the IVF procedures.
