Role of miRNA polymorphisms on male and female infertility and recurrent implantation failure

Abstract Purpose MiRNAs regulate gene expression, impacting reproductive health, such as infertility and implantation failure. This study investigated the association between miRNA polymorphisms and male infertility (azoospermia, oligospermia), female infertility (endometriosis), and recurrent implantation failure in IVF. Methods In order to find relevant articles, a search was conducted in PubMed, WOS, Scopus, and the Cochrane Library databases using Mesh terms and Entry terms with the keywords (miRNA OR microRNA polymorphism) AND (abortion OR miscarriage OR infertility OR sterility OR pregnancy loss OR implantation failure). Results The study revealed miRNA polymorphisms linked to a higher risk of male and female infertility and repeated implantation failure in IVF. These results underscore the significance of genetic variations in miRNAs in developing reproductive issues and the promise of personalized treatment strategies guided by genetic profiles. Conclusion These results provide valuable insights into the genetic basis of infertility and emphasize the need for further research to develop targeted diagnostic tools and therapies. Understanding the role of miRNA polymorphisms in reproductive health has significant implications for improving outcomes for couples struggling with infertility. By elucidating the genetic factors contributing to infertility, this study paves the way for personalized approaches to diagnosis and treatment, ultimately enhancing reproductive care.
