Pain curbs sex drive in female mice, but not in males

Pain from inflammation greatly reduced sexual motivation in female mice in heat — but had no such effect on male mice, a study concludes. “We know from other studies that women’s sexual desire is far more dependent on context than men’s — but whether this is due to biological or social/cultural factors, such as upbringing and media influence, isn’t known,” says a corresponding author of the study. “Our finding that female mice, too, show pain-inhibited sexual desire suggests there may be an evolutionary biology explanation for these effects in humans — and not simply a sociocultural one.”
