Specifically, either genetic deletion (P2X7 knockout mice) or subchronic pharmacological inhibition of the receptor produces a decrease of whole-body energy expenditure and, concurrently, an increase of carbohydrate oxidation. As further evidence, lipid accumulation, increased fat mass distribution, and weight gain are reported in P2X7-depleted mice. Conversely, the stimulation of P2X7 enhances energy expenditure. Altogether, this knowledge supports the role of P2X7 signaling in the fight against obesity and insulin resistance, as well as in the promotion of adaptive thermogenesis.Objective To examine whether the Stop GnRH-agonist combined with multiple-dose GnRH-antagonist protocol may improve conventional IVF/intracytoplasmic sperm injection (ICSI) cycle in poor ovarian response (POR) patients. Design Cohort historical, proof of concept study. Setting Tertiary, University affiliated Medical Center. Patient(s) Thirty POR patients, defined according to the Bologna criteria, who underwent a subsequent Stop GnRH-agonist combined with multiple-dose GnRH-antagonist controlled ovarian hyperstimulation (COH) protocol, within 3 months of the previous failed conventional IVF/ICSI cycle, were included. For the purposes of this study, we eliminated a bias in this selection by including only "genuine" poor responder patients, defined as those who yielded up to 3 oocytes following COH with a minimal gonadotropin daily dose of 300 IU. Main Outcome Measure(s) Number of oocytes retrieved, number of top-quality embryos, COH variables. Result(s) The Stop GnRH-agonist combined with multiple-dose GnRH-antagonist COH protocol revealed significantly higher numbers of follicles >13 mm on the day of hCG administration, higher numbers of oocytes retrieved, and top-quality embryos (TQE) with an acceptable clinical pregnancy rate (16.6%). Moreover, as
