Background & Objective: The study aims to explore the correlations among the counts of mature oocytes, endometrial receptivity, and fertilization rates in in fresh embryo transfer cycles. Materials & Methods: This cross-sectional study involved 136 women who candidates for IVF/ICSI cycles. Based on clinical pregnancy rates, all patients meeting the inclusion criteria were categorized into pregnant and non-pregnant groups. The patients were further classified into three categories according to the count of mature oocytes, the Fertilization Rates (FR), and the endometrial thickness. Results: Fifty-five of the study populations achieved successful pregnancies, 40.4%. The study identified significant differences between the clinical pregnancy rates and the retrieved oocyte counts, mature oocyte counts, Endometrial Thickness (ET), and FR (P<0.05). Mature oocyte count was positively improved IVF/ICSI outcomes (P<0.05). Notably, a strong correlation was identified between FR and IVF/ICSI outcomes (r= -0.796, P<0.001), and between the ET and IVF/ICSI outcomes (r= -0.195, P<0.05) Conclusion: The study revealed the notably impacts of oocytes quality on the clinical and paraclinical outcomes of assisted reproductive technology.
