Same Cycle Shift from IVF with Own Oocytes to Oocyte Donation in No or Poor Response Cycles.

Our In-Vitro Fertilisation Centre is situated in a large developing country, Madagascar, with very bad roads and low income patients. Therefore we try to find ways to reduce as much as possible the number of attempts to obtain a pregnancy. Poor or no response to ovarian stimulation in In Vitro Fertilization (IVF) cycles is a great challenge. Here we describe a method whereby we shift from IVF to Oocyte Donation (OD) during the same cycle for patients whose ovaries do not respond properly to ovulation stimulation. Patients were superovulated with a long protocol agonist treatment and ultrasonically monitored for IVF/ICSI. When, at half way of the stimulation, it was clear that there was a no or poor response, gonadotropin administration was stopped and immediately replaced by estrogens; when the endometrium was considered to be sufficiently receptive, some donated oocytes from our concomitant oocyte donation (OD) program were fertilized with the patient's husband sperm and progesterone was added to the patients' treatment. After 48 hours the resulting embryos were transferred. Five poor responders patients underwent the described procedure. Three conceived, one of which aborted at 9 weeks, while the other two are ongoing. These patients signed the consent form accepting the possibility to shift from IVF to OD during the same cycle and three clinical pregnancies were obtained. OD through this technique seems more acceptable by poor responders than planned OD. This is a preliminary report and to our knowledge it is the first report of such a method.
