Simulated Physiological Oocyte Maturation (SPOM) mimics in vitro the physiological events of oocyte maturation. The system uses cAMP modulators in two steps (pre IVM and IVM) and has presented promising results that are arousing the curiosity of IVF programs in different animal species, generating several papers, adaptations, and controversies worldwide. This study systematically analyses the data in the literature on the use of SPOM and compares the outcomes to the original paper (Albuz et al. Hum. Rep., 25: 2999–3011 2010), classifying them into success or failure. The PubMed, Scopus, and Google Scholar databases were searched and 22 studies were included, from which data on 26 experiments were extracted and evaluated via descriptive statistical analysis. Only experiments that assessed the blastocyst rate (BR) were considered for the success parameter, i.e. success (increase in BR) or failure …
