OBJECTIVE: To evaluate the efficacy of semi natural cycle as option of treatment for the patients who have a poor prognosis to controlled ovarian hyperstimulation (COH). PATIENTS AND METHODS: Prospective study. Sixty-six patients with an ovulatory cycle who presented either altered ovarian status (AOS) or implantation failure (IMF) and had carried out a total of 133 semi natural IVF cycles were included. Once follicular dominance was established, the growth of this follicule was controlled by administration of the GnRH antagonist with exogenous gonadotrophins. RESULTS: Groups AOS (n = 47) and IMF (n = 19) were similar with regard to oocyte pickup rate (81.2% and 81.1%), the oocyte recovery rate (61.4% and 64.8%) and clinical pregnancies per oocyte pickups rate (15.4% and 16.6%), respectively. CONCLUSIONS: The semi natural cycle appears as option of treatment for patients who have a poor prognosis for successful in vitro fertilization.
