FIGURE 1 Schematic representation of the two stimulation protocols. The control group maintained the same dose of rFSH for at least 2 days after starting a GnRH antagonist. The step-up group received an additional dose of 75 IU of rFSH for at least 2 days after starting a GnRH antagonist. Propst. Increasing rFSH with a GnRH antagonist. Fertil Steril 2006.
