Significant differences were observed in age, weight, BMI, basal follicle-stimulating hormone (bFSH), basal progesterone, AMH, AFC, fasting blood glucose, fasting insulin, HOMA-IR, protocol composition, Gn initial dose, Gn duration, and total Gn usage between the two groups (p < 0.05). No statistical significance was observed in the infertility type, infertility duration, polycystic ovary syndrome (PCOS) composition, basal luteinizing hormone (LH) level, estrogen (E2), prolactin (PRL), testosterone (T), and progesterone (P) (p > 0.05).
