Experts say that increased marital satisfaction and enhanced sexual pleasure are found to be linked with doing monotonous and dull household duties.
"By and large, the more men do around the house, the happier women are," sociologist Scott Coltrane of the University of California, Riverside, a co-author of a report published in synopsis form on the website of the Council of Contemporary Families (CCF) told AFP.
"When men do more of the housework, women's perceptions of fairness and marital satisfaction rise and the couple experience less marital conflict," the report says.
The reward for menfolk who help out around the house could be more sex.
"We sociologists generally don't go there, but therapists say there's a direct correlation" between men doing more housework and the frequency of sex, said Coltrane.
In a comment posted on the CCF website, psychologist Joshua Coleman agreed that sharing household chores "is associated with higher levels of marital satisfaction -- and sometimes more sex, too!"
"Wives report greater feelings of sexual interest and affection for husbands who participate in housework," Coleman, who is a senior fellow at the CCF, said.
In addition to doing more boring chores around the home, American men spend three times more time with their kids today than they did in 1960, the study said.
The time women spend with their children has doubled, it said, speculating that both mothers and fathers have set higher parenting standards for themselves.
But all that time spent parenting could have a negative effect on a couple's intimate relationship.
"The increase in parenting hours on the part of both husbands and wives may pose some threats to the couple relationship since many couples have increased their time with their children by eliminating or greatly reducing time for romance," Coleman wrote.
Happily, though, the phenomenon of men chipping in around the home appears to be global, Coltrane said, citing work by co-author Oriel Sullivan, a woman, who is a professor of sociology at Ben Gurion University in Israel.
"Men everywhere are doing more," said Coltrane.
"Even Italian men and Spanish men are doing more ... not huge amounts but more than they used to," he said.
The report praised American couples for the "remarkable progress" they have made in sharing out the responsibilities of working and family care.
Even if men still lag far behind women in terms of what they do around the house, they are moving in the right direction and the gains are unlikely to be reversed, the report summarized.
"Men are still only doing half as much as women do, but we see the bar inching up and we think the process is irreversible," said Coltrane.
The hard-earned gains have been made in spite of the poor social support system for working families in the United States, the report said.
"The US guarantees no paid leave for mothers in any segment of the work force, leaving it in the company of only Lesotho, Liberia, Papua New Guinea, and Swaziland," the report said, referencing a study published last month.
The full report on men and women sharing household tasks is to be presented at the CCF's annual conference next month in Chicago.
