EBV induced loss of sperm quality
Türk 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 ...

Factors affecting sperm quality before and after mating of calopterygid damselflies. [PDF]
PLoS ONE, 2010 Damselflies (Odonata: Zygoptera) have a more complex sperm transfer system than other internally ejaculating insects. Males translocate sperm from the internal reproductive organs to the specific sperm vesicles, a small cavity on the body surface, and ...
