Table 1. Baseline demographic and clinical characteristics of participants in the DGC and MC groups Values are presented as mean±standard deviation for continuous variables and as number (percentage) for categorical variables. Significant differences were observed in female age, male age, and AMH levels (p<0.05). No statistically significant differences were found between groups in BMI, infertility type, duration of infertility, AFC, or causes of infertility. Sample size: DGC group (n=59), MC group (n=60). Abbreviations: DGC=Density Gradient Centrifugation, MC=Microfluidic
