INTRODUCTION: The aim of this study is to provide an updated and comprehensive systematic review on the effects of resveratrol (RSV) in male infertility and sperm preservation. EVIDENCE ACQUISITION: This systematic review followed the MOOSE guidelines for Meta-analyses and Systematic Reviews of Observational Studies and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P). Only original articles evaluating the effect of RSV on human spermatozoa in vivo or in vitro were included. EVIDENCE SYNTHESIS: Of the 1806 abstracts evaluated for eligibility, only 12 studies were included in the qualitative synthesis, of which three were prospective in-vivo studies and nine were in -vitro studies. Out of three human studies on RSV, only two studies administered RSV alone, one of them reported a positive impact and the other reported no significant impact on semen parameters. Overall, the in -vitro studies have reported the ability of RSV to protect spermatozoa against damage due to freeze-thaw cycles during cryopreservation. Other in -vitro studies have reported positive effects of RSV in fresh samples and protective effects in cell lines. CONCLUSIONS: Available in-vivo studies are controversial with regard to the effect of RSV in improving semen parameters. In -vitro studies support the use of RSV before sperm cryopreservation. Further well-designed prospective studies on large sample sizes are needed to fully understand the role of RSV in the treatment of male infertility in vivo.

Abstract

INTRODUCTION: The aim of this study is to provide an updated and comprehensive systematic review on the effects of resveratrol (RSV) in male infertility and sperm preservation. EVIDENCE ACQUISITION: This systematic review followed the MOOSE guidelines for Meta-analyses and Systematic Reviews of Observational Studies and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P). Only original articles evaluating the effect of RSV on human spermatozoa in vivo or in vitro were included. EVIDENCE SYNTHESIS: Of the 1806 abstracts evaluated for eligibility, only 12 studies were included in the qualitative synthesis, of which three were prospective in-vivo studies and nine were in -vitro studies. Out of three human studies on RSV, only two studies administered RSV alone, one of them reported a positive impact and the other reported no significant impact on semen parameters. Overall, the in -vitro studies have reported the ability of RSV to protect spermatozoa against damage due to freeze-thaw cycles during cryopreservation. Other in -vitro studies have reported positive effects of RSV in fresh samples and protective effects in cell lines. CONCLUSIONS: Available in-vivo studies are controversial with regard to the effect of RSV in improving semen parameters. In -vitro studies support the use of RSV before sperm cryopreservation. Further well-designed prospective studies on large sample sizes are needed to fully understand the role of RSV in the treatment of male infertility in vivo.
