All plastics are endocrine disruptors [a], though the an easy filter is softer = worse. If anything food related is in contact with plastic there will be plastic in the food. The pH and temperature of the food have a big impact on plastic leaching.

And sperm quality mostly affect fertility. The egg and the body if the woman is incredibly effective at selecting quality sperm and rejecting bad sperm. There are multiple guidance systems for sperm which selects for good quality [b].

Plastic is generally defined by its mechanical and thermal properties and a dominance of polymers. There’s are lots and lots of different chemicals used as plastics today and they have wildly different chemical properties. It seems incredible to state that “all plastics” are endocrine disruptors. Many plastics are essentially chemically inert in a biological sense. In some ways DNA itself can be seen as a plastic being a biopolymer if it were handled properly and in enough quantity. As an uneducated layman my intuition, and the links you provide, is that the additives and monomers added to plastic to modulate their mechanical and chemical behaviors are most likely to be the chemically reactive part that can be disruptive to our biology. I didn’t find a reference to a single plastic in your references. This applies to the leaching comment as well - I suspect you mean ph and temp increase the leaching of the additives from the plastic.

Am I right?

plasticizers are a component of plastic, characterizing one ingredient in plastic as an 'additive' in order to shift the blame from plastic to plastic ingredients doesn't change the basic fact that plastics are endocrine disruptors because they leach plasticizer into food.

To be fair, DNA absolutely disrupts all kinds of biological processes - that's why viruses do anything, for example. And random nonsense DNA that you'd see if someone was using it as a plastic would probably uncover new and exciting failure modes that existing biological systems haven't had to deal with before because nothing natural produces pure DNA in absurd enough quantities to make plastic bottles out of.
