The amount of hours a woman works does not predict whether or not she will want to have sex. 

That’s what a study by DeLamater and Hyde said a decade or so ago.  They found that whether or not a woman was at home, worked 20 hours or less, 40 hours, or even 60 hours a week, work had a negligible effect on how much sex they had. 

They said the real culprit to low sexual desire was fatigue, and whether or not the woman liked her job. 

This was reprinted recently in the news but I feel the article can leave the wrong impression.

Fatigue is the number one cause of low sexual desire in women.  But to say that no matter how many hours of work you’ve done you’ll still want to have sex as long as you like your job just doesn’t make practical sense.

Long job hours and fatigue are so closely interwoven; I don’t think they can truly be separated.
