Sperm Mesoderm Specific Transcript Gene Methylation Status in Infertile Patients: A Systematic Review and Meta-Analysis.
Purpose: The mesoderm specific transcription (MEST) gene is a paternally expressed imprinted gene that appears to play a role in embryo survival. The latest meta-analysis on MEST methylation pattern in spermatozoa of infertile patients found higher methylation in spermatozoa from infertile patients than fertile controls. To provide an updated and comprehensive systematic review and meta-analysis on the MEST gene methylation pattern in patients with abnormal sperm parameters compared to men with normal parameters.
Materials and methods: This meta-analysis was registered in PROSPERO (CRD42023397056) and performed following 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 MEST gene methylation in spermatozoa from patients with infertility or abnormalities in one or more sperm parameters compared to fertile or normozoospermic men were included.
Results: Of 354 abstracts evaluated for eligibility, only 6 studies were included in the quantitative synthesis, involving a total of 301 patients and 163 controls. Our analysis showed significantly higher levels of MEST gene methylation in patients compared with controls (standard mean difference [SMD] 2.150, 95% confidence interval [CI] 0.377, 3.922; p=0.017), although there was significant heterogeneity between studies (Q-value=239.90, p<0.001; I²=97.91%). No significant evidence of publication bias was found, although one study was sensitive enough to skew the results, leading to a loss of significance (SMD 1.543, 95% CI -0.300, 3.387; p=0.101). In meta-regression analysis, we found that the results were independent of both ages (p=0.6519) and sperm concentration (p=0.2360).
Conclusions: Sperm DNA methylation may be associated with epigenetic risk in assisted reproductive techniques (ART). The MEST gene could be included in the genetic panel of prospective studies aimed at identifying the most representative and cost-effective genes to be analyzed in couples undergoing ART.
