If the process was directed (and you neglect to mention who your director might be, but I think I get the hint) then why lower the ovaries at all? Why not descend the testicles and leave the ovaries where they were? Of course, if the whole business evolved, it might make sense...
I don't see your point. The process of polarization involved both sexes.
My point it simply that if the human body were designed, then there would be no need for the designer to cause both ovaries and testes to descend, when he only intended to affect testes.
Both organs displaying similar properties suggests that they both evolved under the influence of the same basic adaptation.
By the way, this "process of polarization" that you mention has been part of our basic phenotype since the evolution of the flatworm. This is why you don't see organisms with a head at each end.
Incidentally, if you think that external testes are such a poor model, what makes you think that they were designed? Unless, of course, you think that they were designed by an idiot.
