But there are fears about the financial and social impact of herbivores. Their low levels of spending and lack of interest in sex invoke two of Japan's biggest problems: its lackluster economy and declining birthrate. Herbivores like to be friends with women — but for many, that's as far as it goes.

In the streets of Harajuku, Alex Fujita explains why he is not interested in taking it any further.

"Nowadays, women have more education and enjoy working. Women are scary now," he says.

And, of course, there is a name, too, for the economically empowered working Japanese women who know what they want: the carnivore women. With herbivore boys and carnivore girls, it seems the land of samurai, sumo wrestlers and geisha girls is remaking its gender landscape anew.

Abstract

Xenoestrogens are endocrine-disrupting chemicals that mimic the action of endogenous estrogen hormones. Effects of xenoestrogen on aquatic wildlife are well documented, whereas the experimental evidence for impairment of reproductive behavior and physiology in mammals after exposure to xenoestrogens has been debated. The strongest arguments against such studies have been that the route, time course, and intensity of exposure did not simulate environmental exposure and that the chemicals tested have additional nonestrogenic toxic effects, hindering generalization of actual xenoestrogenic effects. Here we show that environmental-like exposure to the pure estrogen 17alpha-ethinylestradiol during development alters reproductive behavior and physiology in adult female Sprague-Dawley rats. We simulated environmental exposure by giving low doses (0.4 and 0.004 microg/kg.d) of 17alpha-ethinylestradiol orally to pregnant females from conception to weaning of the pups, which continued to receive the treatment until puberty. We studied the sexual behavior, estrous cycle, and estradiol plasma levels of intact female rats when they reached 3 months of age. Exposure to the higher dose strongly affected female sexual behavior and physiology, with suppression of lordosis and the estrous cycle and enhanced aggression toward males. The lower dose disrupted appetitive components of sexual behavior that influence the rate of copulation. Estradiol plasma levels were not affected by the treatment. Our study revealed that exposure to low oral doses of a pure estrogen during development alters female sexual behavior and physiology. These results suggest potential risks of reproductive failure from xenoestrogen exposure in realistic ecological conditions.
