It’s not necessarily always a result of the virus itself, but things like the Zika virus can influence testicular tissue and germ cells, as ZIKV replicates in those cells: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6159993/
But as for a minor case of influenza or the common cold, I would be wary about the rising temperature in the body due to the immune response. That can impact sperm production and integrity.
