Abstract

We aim to assess the in vitro fertilization-embryo transfer (IVF-ET) outcome in patients receiving an extremely high 450 daily dose (IU) of gonadotropins during controlled ovarian hyperstimulation (COH) for IVF. Moreover, in those who failed to conceive while using 450 daily dose (IU) of gonadotropins, we aim to evaluate whether increasing the daily dose gonadotropins to 600IU will improve IVF outcome. All consecutive women, admitted to our IVF unit and underwent COH consisting of daily gonadotropin dose of 450IU were included. Ovarian stimulation characteristics, number of oocytes retrieved, number of embryo transferred and pregnancy rate were assessed. Nine-hundred one consecutive IVF cycles were evaluated. While there was no between-group difference in the duration of COH, patients who conceived were significantly younger, yielded higher number of oocytes retrieved and embryos transferred and had significantly lower cancellations. In a sub-Analysis, including only those patients who failed to conceive while using 450 daily dose (IU) of gonadotropins, and who underwent a subsequent IVF cycle attempt with the used of 600IU daily dose of gonadotropins, no improvements in COH characteristics or cancellation rates were observed with increasing the daily gonadotropin dose to 600IU. To conclude, in poor responders undergoing COH with an extremely high daily gonadotropin dose (450IU), the most important factors that predict IVF success are female age and the number of oocytes retrieved. Moreover, patients who failed to conceive on a daily gonadotropin dose of 450IU will not benefit from increasing the dose to 600IU and should therefore consider the options of egg donation or adoption.
