Analyzing them, regarding either concentration or genetic/epigenetic status can provide helpful information about disorders, response to treatments, estimation of success rates, etc. Moreover, since they are presented in body fluids, evaluation of the aforementioned items would be achieved by less/non-invasive methods. In human reproduction field, it is required to have biomarkers for prediction of assisted reproduction techniques (ART) outcome, as well as some non-invasive procedures for genetic/epigenetic assessments. cfDNA is an appropriate candidate for providing the both approaches in ART. Recently, scientists attempted to investigate its application in distinct fields of reproductive medicine that resulted in discovering its applicability for biomarker and genetic/epigenetic analyses. However, due to some limitations, it has not reached to clinical administration yet. In this article, we have reviewed the current reported data with respect to advantages and limitations of cfDNA utilization in three fields of ART, reproduction of male and female, as well as in vitro developed embryos. This systematic review aims to verify the efficacy of acarbose monotherapy in treating obese or overweight patients without diabetes. In the study, we conducted a systematic search of the Pub-Med, EMBASE, Cochrane and Science Citation Index Expanded databases in search of clinical trials on acarbose treatment, overweight and obesity. The crucial inclusion criteria were as follows (1) patients were diagnosed as overweight or obese (BMI ≥ 25kg/m ); (2) randomized controlled trials (RCTs); (3) patients had undergone acarbose monotherapy or placebo control; (4) acarbose treatment had been carried out for at least 3 months. Exclusion criteria were as follows (1) patients diagnosed with diabetes mellitus (DM); (2) patients had received
