Multifactorial stepwise regression analysis showed that female age (0.95 [0.92–0.97], P = 0.000), decreased ovarian reserve (0.27 [0.19-0.38]), P = 0.000), endometriosis (0.81 [0.56-0.86], P = 0.000), antral follicle count (1.09 [1.06-1.12], P = 0.000), basal follicle-stimulating hormone (0.90 [0.85-0.96], P = 0.001), Anti-Mullerian hormone (1.19 [1.13–1.26], P= 0.000) and luteinizing hormone on trigger day (0.73 [0.66–0.80], P= 0.000), were independent factors for the occurrence of different ovarian responses during ovarian hyperstimulation. This evidence concerns the gene AMH and endometriosis.
