[QUOTE="madman, post: 194349, member: 13851"] [B]Figure 3. Possible mechanism of SARS-CoV-2 invasion in the reproductive system of infected men and the potential health impacts associated.

The immune response triggered by viral entry produces various inflammatory substances, such as cytokines, which induce OS in testicular cells, which in turn damages the DNA of developing spermatozoa.
