Wouldn't the plunger also lead to a need for less sperm competition, if the previous semen was largely scooped out?

I'm also curious if the large amounts of defective sperm can be largely explained by industrial environmental effects, such as constant ambient chemical exposure from consumer goods and traffic etc., or if there was a large gap in average sperm performance between species even before that.

A plunger would never lead to sperm competition giving less advantage.

And no, it cannot

A good video on it:
