Abstract

We aim to retrospectively evaluate the role of increasing the gonadotropin daily dose from 450 IU/day to 300 IU twice a day on IVF-ET outcome in poor responder patients. All consecutive women admitted to our IVF unit and underwent COH consisting of daily gonadotropin dose of 450 IU, followed by an IVF cycle using 300 IU twice a day, were included. Ovarian stimulation characteristics, number of oocytes retrieved, number of embryo transferred and pregnancy rate was assessed. Twenty-three patients undergoing both cycles were evaluated. While there was no between-group difference in the duration of COH, number of 2PN embryos, fertilization rate and number of embryos transferred, patients receiving daily gonadotropin 300 IU twice a day achieved a significantly higher peak estradiol levels (3350.39 ± 2364.26 vs. 2223.74 ± 1299.91; p <.03, respectively), and yielded significantly higher number of follicles >15 mm in diameter on day of hCG administration (3.2 ± 2.4 vs 1.8 ± 1; p <.03, respectively) and higher number of oocytes retrieved (3.48 ± 2.54 vs 1.87 ± 1.1; p <.02, respectively) with an acceptable live birth rate (5%). To conclude, in poor responders undergoing COH a daily gonadotropin dose of 450 IU, increasing the dose to 300 IU twice daily may result in higher oocyte yield, with the possible improvement in IVF outcome.
