Each cycle of IVF is a multistep process that is keyed to a patient's menstrual cycle in the beginning. First, a patient needs to take injectable hormones every day for a 10- to 12-day period, explains Dr. Eve Feinberg, a reproductive endocrinologist and infertility specialist at Northwestern University in Chicago. Those hormones prime multiple eggs to mature inside the ovary, in little fluid-filled sacs called follicles. Patients are monitored regularly, often daily. Once those follicles reach a certain size, the patient takes a different hormone that gets the eggs ready to be retrieved.
