释放到环境中的雌激素内分泌干扰化学品有可能影响动物行为。本研究探讨了血浆性腺类固醇水平与行为之间的关系，以及外源激素干扰对筑巢雄性三棘鱼行为的影响。血浆性腺类固醇浓度与筑巢和攻击行为的水平：雌二醇水平呈负相关的求爱行为，而11-酮睾酮水平呈负相关的筑巢行为。暴露于环境相关浓度的内分泌干扰物的雄性三棘鱼的行为与对照雄性的行为不同。对照组雄性动物随着时间的推移增加了对活雄性同种动物的攻击性反应，而暴露于炔雌醇的雄性动物则降低了攻击性反应。这项研究提供了进一步的证据，表明环境中低水平的内分泌干扰化学物质可能对动物行为产生微妙而重要的影响。(C)2001年，动物行为研究协会。
Oestrogenic endocrine-disrupting chemicals released into the environment have the potential to affect animal behaviour. This study examined the relationship between plasma levels of gonadal steroids and behaviour and the effects of exogenous hormonal perturbation on the behaviour of nesting male three-spined stickleback. Plasma gonadal steroid concentrations were related to levels of nesting and aggressive behaviours: levels of oestradiol were negatively related to courtship behaviours while levels of 11-ketotestosterone were negatively related to nesting behaviours. The behaviour of male three-spined stickleback exposed to environmentally relevant concentrations of an endocrine disrupter differed from the behaviour of control males. Control males increased their aggressive response to a live male conspecific over time, while males exposed to ethinyl oestradiol decreased their aggressive response. This study offers further evidence that low levels of endocrine-disrupting chemicals in the environment may exert subtle yet important effects on animal behaviour.
