我们发现，生殖成熟的配偶海七鳃鳗释放胆汁酸，作为一个有效的性信息素，诱导偏好和排卵的女性七鳃鳗搜索行为。分泌的胆汁酸7 α，12 α，24-三羟基-5 α-胆烷-3-酮24-硫酸盐相对于已知的脊椎动物类固醇信息素以高得多的量释放，并且可能通过鳃分泌。因此，这种鱼类的配偶通过分泌一种可以在长距离内起作用的信息素来向雌性发出其生殖状态和位置的信号。
We show that reproductively mature mate sea lampreys release a bile acid that acts as a potent sex pheromone, inducing preference and searching behavior in ovulated female lampreys. The secreted bile acid 7alpha,12alpha,24-trihydroxy-5alpha-cholan-3-one 24-sulfate was released in much higher amounts relative to known vertebrate steroid pheromones and may be secreted through the gills. Hence, the mate of this fish species signals both its reproductive status and location to females by secreting a pheromone that can act over long distances.
