Background: Assisted reproductive technology (ART) helps infertility treatment. In this study, the researchers tried to find several prognostic factors for ART success. Methods: Data of 189 couples that had undergone ART at Qadir-Mother and Child hospital, were retrospectively explored. Cycles were classified as succeeded/failed and female/male/combined causes. Three classes of ovarian response based on the number of retrieved oocytes were determined. Duration of ovarian stimulation, dosages of gonadotropins, and sperm parameters were evaluated. Chi square, t-test and Pearson correlation were used for the analysis. Results: Couples with male factor infertility had a higher success rate. Female age had a negative correlation with follicle count (r =-0. 25), retrieved oocytes (r =-0. 25), fertilized oocytes (r=-0. 2), and clinical pregnancy (r =-0. 21). Female age was negatively correlated with AMH, although not significant. The fertilization rate had a reverse correlation with the basal FSH (r =-0. 22, P= 0. 01) and LH (r=-0. 18, P= 0. 05). Finally, ART success rate was positively correlated with the number of follicles before (r = 0. 18, P = 0. 05) and after retrieval (r = 0. 15, P = 0. 05) and fertilized oocyte (r = 0. 23, P = 0. 01). Conclusions: Female age, the number of mature follicles before retrieval, the number of retrieved oocyte, and fertilized oocytes are predictive factors in ART outcomes.
