>and there’s a difference between merely being stressed and a systemic stress response that would affect the sperm production (which, by the way, doesn’t occur just during sex but before). According to the way the research was described, this mechanism acts outside of the genetic code, so it isn’t a matter of when sperm is produced. These particles can latch on to the gamete long after the gamete is produced. For example they can be present along the lining or interstitial fluids in the epididymis, where sperm passes through from the testes during reproduction.
