Table 5 The Gonadotropin ratio range of hMG:rFSH of 0.3ā€“0.6 was the most predictive of the optimal live birth rate (LBR): (LBR of 55.4% vs. 41.4%; pā€‰=ā€‰0.010, 95% CI 0.176, 1.311)

From: hMG addition affects the change in progesterone level during IVF stimulation and LBR: a retrospective cohort study
