That hypothesis is sensible.

According to The Male Brain, by psychiatrist Louann Brizendine, males have 2.5x the space devoted to sexual drive in the hypothalamus compared to females.

By the time males reach puberty, guy’s sexual occupation and fertile female tracking circuits run in the background non-stop like an unkillable daemon process.

That’s absolutely going to divert brainpower.

Speaking personally, I feel that the experience of sexual attraction and sexual desire has been a stimulus to the development of my intelligence, not a brake upon it. If you look at great art and literature you will see it has played a crucial role there too. So no, I don't think it is a 'sensible hypothesis'.

Oh, absolutely. For a tiny percentage of creative and productive people. For the masses, however, I don't see it.
