Murine cytomegalovirus infection of mouse testes.
With the aim of illustrating a mechanism of cytomegalovirus (CMV) venereal transmission, we induced murine CMV infection in the mouse testes of immunologically competent mice. Using in situ cytohybridization, we were able to show that murine CMV-specific DNA was associated with spermatocytes and mature sperm. Electron microscopy studies also supported sperm infection. The virus could be reisolated from infected epididymal sperm by cocultivation with mouse embryo fibroblasts. We found no difference in either the sexual performance or the fertilization efficiency of the sperm between infected and uninfected males.
