It is now well established that female goldfish release unmodified and metabolized sex hormones to the water and that some of these compounds function as potent sex pheromones detected by the male's olfactory sense. In goldfish, both olfactory pheromonal receptors and their corresponding hormonal receptors appear to be transmembrane-domain receptors coupled with G proteins. Recent studies of other teleost fish indicate that fish commonly use `hormonal-pheromones.' Taken together, these data suggest that fish pheromone systems may have evolved as a consequence of a chance expression of hormone receptor molecules on olfactory receptor cells. Isolation and identification of olfactory and hormonal receptors may be the next step in resolving this question.
现已充分证实，雌性金鱼会将未修饰和经过代谢的性激素释放到水中，并且其中一些化合物可作为由雄性嗅觉检测到的强效性信息素发挥作用。在金鱼中，嗅觉信息素受体及其相应的激素受体似乎都是与G蛋白偶联的跨膜结构域受体。最近对其他硬骨鱼的研究表明，鱼类通常会使用“激素信息素”。综合这些数据表明，鱼类信息素系统可能是由于激素受体分子在嗅觉受体细胞上的偶然表达而进化而来的。分离和鉴定嗅觉受体和激素受体可能是解决这个问题的下一步。
