BACKGROUND: The usefulness of determination of endometrial thickness and pattern by ultrasound for pregnancy prediction has been confirmed as well as questioned in the literature. In an effort to help clarify this controversial issue and to find the relation between endometrial thickness and pattern and pregnancy rates, this study was undertaken. METHODS: This was a cross-sectional study. One thousand and thirty infertile couples with ovulatory factor infertility that underwent 1,030 cycles of induction of ovulation were included in this study. All patients charts were reviewed for endometrial thickness «7, 7-14 and (GREATER THAN)14 mm) and pattern (triline versus homogenous) on the time ofHCG administration. Age, duration of infertility and number of follicles were evaluated in all patients. Treatment outcome was clinical pregnancy rate. The SPSS 10 software and chi-square t-test and ANOVA were applied for statistical analysis. P(LESS THAN)0.05 was determined as statistical significant. RESULTS: The overal1 pregnancy rate was 25.8% (266 from 1030). There was no statistically significant difference in pregnancy rates in three groups of endometrial thickness «7, 7-14, (GREATER THAN)14 mm) and two groups of endometrial patterns (trilene and homogenous). CONCLUSIONS: This study showed that there is no significant relation between endometrial thickness and pattern and pregnancy rate. Further studies are recommended
