Cosmic inflation doesn't make your balls or penis bigger, if that's what you are thinking.

I object to their description of organs migrating.
The testicles don't descend. At the time they were close to the kidneys, the embryo was only 10mm long. What happened was that the tissue between them and the heart grew much more than that between them and the pubis.
It's sort of like cosmic inflation. Things get farther apart without moving.
Well, for most people the testicles do descend in the relative sense. For some people one or both testicles don't descend and they end up with just one ball in their scrutum, or no balls outside their body wall at all.
