 Patients who have undergone in vitro fertilization IVF and produced four or less follicles or had four or less oocytes eggs retrieved are often referred to as poor responders. We will refer to these patients from this point forward as low responders to avoid using a potentially offensive label. We are currently using 2 different IVF medication protocols in our practice to treat low responder patients with infertility: the Microdose Leuprolide protocol and the Luteal Phase Ganirelix protocol. We would like to conduct a randomized-controlled trial and randomize patients to one treatment group or the other to determine which medication protocol is more effective in treating infertility in this group of patients.
