Assisted reproductive technology (ART) helps infertility treatment. In this study, the researchers tried to find several prognostic factors for ART success.
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.
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).
Female age, the number of mature follicles before retrieval, the number of retrieved oocyte, and fertilized oocytes are predictive factors in ART outcomes.
