British universities have found that a high IQ is an advantage for men who want to get married, but a hindrance for women.

Why do you think this is? In the article, one quote postulates that intelligent women don't find men "interesting." It's not that -- it's that most men don't want to compete with a mate of higher intellect at home, or that women want to make sure that their husbands are as bright (or brighter) than they, and for women with high IQ's, that narrows the pool considerably.
