A new study finds that men married to women with higher incomes are more likely to use erectile dysfunction medications than their male breadwinning counterparts.
Researchers from Washington University in St. Louis's Olin Business School, along with colleagues in Denmark, looked at more than 200,000 married couples in Denmark from 1997 to 2006. Wives who outearned their husbands were also more likely to suffer from insomnia and to take anti-anxiety medications. However, these effects didn't hold true for unmarried couples or for men who had earned less than their wives before marriage.
Findings appear in the Personality and Social Psychology Bulletin.
Another study published in the journal Sex Roles last year finds that macho men whose partners earn more than they do have worse romantic relationships, in part because the difference in income is a strain for them. Conversely, men who are not so traditional in their masculinity do not place as much importance on the difference in income and, as a result, appear to have better-quality relationships with their female partner, the researchers said.
