Design of the study. Prospective cohort clinical study. In the period April 2016 to April 2018, a total of 60 patients met the inclusion criteria. Patients were assigned to three groups, all based on the use of a GnRH antagonist scheme. After the oocyte recovery, each patient’s pooled FF samples from the first gentle aspiration were divided in 4 aliquots and collected in cryotubes for examination of leptin, VEGF, MMPs, and NO2/NO3 quantification
