The cycles were divided into three groups based on their indexes (groups A, B, and C). Each of the groups received a different type of FSH during treatment. A cross-group comparison was then undertaken to evaluate the growth and development of the three largest follicles and the patients’ pregnancy-related indexes between the normal-response and high-response populations.Results: In the normal-response populations, the number of high-quality embryos obtained in groups A and B was significantly higher than in group C, and the FSH dosage was significantly lower than in group C (P < 0.05). There were more follicles with a diameter of 16– 18 mm found in group A than in group C on the day of hCG injection (hCG day) (P < 0.05), but there were no significant differences in the groups in other indicators. In the high-response populations, the number of oocytes retrieved and high-quality embryos obtained in group A were significantly higher than in group C (P < 0.05), and the total dosage and duration of FSH stimulation in group C were significantly higher than groups A and B (P < 0.05).Conclusion: Three different types of FSH led to comparable growth rates of the three largest follicles and clinical pregnancy rates per fresh cycle in long-protocol COH treatment.Keywords: follicle-stimulating hormone, follicle growth rate, high-quality embryos, Gn stimulation duration, follicle distribution on hCG day
