The Chore Split Sets the Mood: What a New Study Says About Desire

It turns out the fastest way to cool the mood in a relationship may be an unfair chore chart. According to new research out of CU Boulder, women who do a larger share of household labor report lower sexual desire for their partner — but the effect hinges on what those women believe about gender roles. In short, the chore split sets the mood: what a new study says about desire is that fairness in the home and heat in the bedroom run on the same wiring.

The work comes from Alexandra Liepmann, a clinical graduate student in the University of Colorado Boulder Department of Psychology and Neuroscience, who led two preregistered studies with co-authors Emily J. Cross and Amy Muise. The paper, published online in April 2026 in The Journal of Sex Research, tracked nearly a thousand participants across two designs. In the first study, 163 couples completed a baseline survey and were then observed across three weeks; in the second, the team replicated the approach with 617 individuals in relationships.

To measure who does what at home, the researchers went far beyond "who does the dishes," using a 59-question scale that covered both visible tasks like cleaning and cooking and the invisible kind: encouraging a child and asking how their day went, or the social planning behind date nights and gatherings. That level of granularity matters — the mental load rarely shows up on a chore chart.

The headline finding is striking. Women who held egalitarian beliefs — that is, women who rejected traditional gender roles — reported the highest desire for their partner when chores were split evenly, and the lowest desire when they were doing more than their share. In the middle of the spectrum, nothing much changed. As Liepmann put it: "How household chores are divided up is important for women's sexual desire for their partner, especially when women want equity in their relationships."

Egalitarian beliefs flip the equation

Not every woman responded the same way, and that difference is the study's core insight, reported by the university. The researchers measured benevolent sexism — the worldview that idealizes traditional gender roles and praises women who fit the caregiver-and-homemaker mold. Women who endorsed those beliefs more strongly did not show the desire drop when labor was unequal. But the authors caution against reading that as an endorsement of traditional roles. Those apparent "benefits," they warn, work by masking the broader costs that such beliefs carry for women across relationships and society — a counterpoint worth sitting with before anyone uses the finding as a defense of the status quo.

There was one group for whom attitudes made no difference at all: mothers. Women with children who carried more of the household load reported the lowest desire regardless of their gender-role beliefs. Prior work has shown that the division of labor tends to become more gendered once couples have kids, even in partnerships that started out egalitarian, which makes the finding especially consequential for young parents. Liepmann's advice was direct: parents should be especially mindful of how household tasks are divided and how that division may be related to their sex lives.

"Couples should be having honest and open conversations about division of household chores and be aware that this has implications elsewhere in the relationship," Liepmann said in a statement to the university. She added that her team is now studying how couples actually talk about chore division, with an eye toward an intervention trial that would assign tasks intentionally to see whether equity can be engineered — and whether desire follows.

An earlier study found a similar pattern

Liepmann's team is not the first to connect the laundry pile to the bedroom. A 2022 study in the Archives of Sexual Behavior, led by Emily Harris and colleagues, surveyed more than seven hundred women partnered with men who also had young children, and found that women who did a large share of housework were significantly more likely to perceive their male partners as dependents — blurring the line between partner and another person to take care of — which in turn tracked with lower desire. That work also found perceived unfairness of the split played only a weak role, suggesting the mechanism is less about resentment over the division itself and more about what the imbalance does to how a woman sees her partner.

Both studies, according to the researchers, support the heteronormativity theory of low desire: the idea that structural gender inequities in mixed-gender relationships shape women's desire more than hormones or stress alone.

What this means for couples sharing a home

For young couples splitting a lease, the takeaway is practical rather than clinical. First, audit the invisible load: the study's 59-question scale is a reminder that "equal chores" usually means more than splitting the dishes, since planning, remembering, and emotional caretaking rarely show up on a chore chart. Second, fairness is relative to expectations — the mismatch between what partners agreed a fair split looks like and what actually happens is where desire takes the hit. Third, the parent finding deserves special attention from couples thinking about kids: labor tends to drift toward gendered patterns after children arrive, so the conversation about who does what needs to happen early, not after resentment sets in.

None of this replaces the usual suspects — stress, health, conflict — as factors in low desire. But it reframes desire as something that can live or die in the mundane details of shared life. The chore split sets the mood: what a new study says about desire amounts to a simple equation — equity in the kitchen tracks with heat in the bedroom.
