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.
