ABSTRACT
Intra cytoplasmic sperm injection [ICSI], is a procedure adopted worldwide as the ultimate micro-assisted fertilization approach due to its clinical success.The objective of this study was to assess the value of using Chromohystroscopy modality in infertility workup after failed ICSI procedures in evaluating uterine receptivity and detect any signs of chronic endometritis by a less invasive method. Prospective cohort study. A total of 50 infertile patients recruited from the infertility clinic in El-Shatby University Hospital, Faculty of Medicine, Alexandria University. Cases were allocated into two groups. The first group includes cases that had a foiled trial of intracytoplasmic sperm injection. The second group includes control cases from patients seeking for fertility treatment with no previous history of intracytoplasmic sperm injection and with no history of anatomic uterine abnormalities. The selected sample size was found to be 50 women, and were randomly selected and allocated in two groups each group was 25 women after fulfilling the inclusion criteria.There was a statically significant increase in the incidence of endometritis among the study group 68%in comparison to 16% in the control group .In this study. Endometrial dyeing with methylene blue at hysteroscopy improves the detection of chronic endometritis
