Purpose: The aim of our study is to evaluate the factors affecting pregnancy success rate in infertile women who underwent intracytoplasmic sperm injection as an assisted reproductive technique. Materials and methods: Between January 2018 and December 2020, 325 cycles of 283 infertile patients who underwent intracytoplasmic sperm injection and a single fresh embryo transfer were included in the study. Age of patients, BMI, causes of infertility, number of collected oocytes and maturation rate, endometrial thickness on embryo transfer day, quality of embryo and transfer day were determined. In addition, anti-Müllerian Hormone, basal FSH, LH, estradiol (E2) levels and E2 and progesterone (P) levels on the day of Human Chorionic Gonadotropin (hCG) administration and pregnancy outcomes were evaluated. Results: Age of women (p=0.015), basal FSH level (p=0.005), AMH (p=0.002), number of oocytes obtained (p=0.003), number of MII oocytes (p=0.001), embryo quality (p<0.001) and embryo transfer rate on fifth day (p<0.0001) were found to be statistically significant in cycles resulting in a pregnancy (n:141) compared to nonsuccesful cycles (n:184). BMI (p=0.814), basal E2 level (p=0.411), E2 (p=0.056) and P (p=0.119) levels on hCG day, EMT (p=0.146) on ET day, oocyte maturation index (p=0.140) and total progressive motile sperm count (p=0.747) were not significantly different between the groups. When the effects of infertility causes on pregnancy succes rate were evaluated, there was no significant differences between the groups. Conclusion: The most important prognostic factors in predicting pregnancy success rate in infertile women who underwent ICSI are maternal age, embryo quality and transfer day.
