After adjusting for confounding factors (including female age, number of oocytes retrieved, infertility etiology, AFC, insemination method, BMI, baseline FSH, AMH, total Gn dosage, and endometrial thickness), the CLBR per oocyte retrieval cycle was significantly lower in the GnRH-A protocol compared with the GnRH-a protocol (odds ratio (OR) = 0.63, 95% confidence interval (CI): 0.464–0.856, P = 0.030). This evidence concerns the gene AMH and Infertility.
