Abstract
A total of 55 infertile females candidate for ICSI for the 1st time or had history of previous failed ICSI were enrolled after fulfilling certain inclusion and exclusion criteria. A premenstrual hysteroscopic examination was performed for all participants one cycle prior to ICSI cycle to assess endometrial glandular openings and vascularity, cervical canal, tubal ostia and endometrial polyp. A new hysteroscopic scoring system of 8 points had been formulated giving 3 points for normal tubal ostia, 2 points for normal cervical canal, another 2 points for the absence of endometrial polyps and 1 point for good endometrium. Hysteroscopic score was calculated depending of the weight of each positive hysteroscopic finding in affecting clinical pregnancy and implantation rates.
The aim of the study was to assessthe role of hystroscopic scoring of uterine cavity and endometrium in prediction of endometrial receptivity and implantation prior to ICSI cycles.
Our results showed that for each assessed hysteroscopic finding clinical pregnancy rates were higher in females with negative findings and females with higher hysteroscopic score (6/8-8/8) had statistically significant higher implantation rates and clinical pregnancy rates than patients with lower score (<6/8). And we recommend hysteroscopic examination prior to involvement in ART for diagnosis and treatment of uterine abnormalities using our hysteroscopic scoring system.
