The overarching objective of this research is to generate clinical evidence to argue the benefits of long acting stimulation protocol compared to the daily stimulation protocol in poor ovarian responder bologna' criteria patients after controlled ovarian stimulation. Reduction in the proportion of subjects with progesterone \> 1.1 ng/ml on the day of triggering (day + 13) in the experimental group compared to the control group is expected.
Each patient will receive a first visit for infertility where will be collected subject history and baseline information, and meet all the inclusion / exclusion criteria. Eligible patients who agreed to participate will be randomized to either long acting standard COS with corifollitropin alpha or standard COS with daily FSH in a fixed GnRH antagonist protocol. All patients will be allowed to participate in the study only once and a written informed consent will be obtained from all, following consultation and before the initiation of the treatment. The endocrine profile of all the patients will be evaluated by analysis of serum progesterone, 17b-estradiol (E2), FSH and LH at different time points: basal condition, during stimulation, at the hCG day and at pick-up. Transvaginal follicular aspiration will be performed by ultrasound guidance 36 hours after hCG administration. The day of pick up oocytes will be fertilized with partner's semen; after 3-5 days, on the base of its evolution, embryo will be transferred. 14 days after embryo-transfer a preg-nancy test will be performed. Follow up in case of obtained pregnancy will be done until 20 weeks of gestation and considered as ongoing pregnancy. The entire duration of the study is 24 months, the follow up of the last patients enrolled will be 6 months.
