EBV induced loss of sperm quality

open access: yesTürk Üroloji Dergisi/Turkish Journal of Urology, 2021
To analyze the presence of Epstein-Barr-virus (EBV) in sperm samples from patients diagnosed with some impairment of the fertility parameters evaluated using seminogram and to observe if there is any difference with the normozoospermic samples. We hypothesize that an EBV infection is responsible for the upregulation of the miRNA 199-3p, which binds to ...
