The authors demonstrated that these mice, lacking serotonin, did not distinguish between sexual partners, mounting male and female mice with seemingly equal fervor. Not only that, the mice showed the same scent preferences for male and female mice and vocalized for male and female mice equally. When the serotonin in these animals was replaced, they preferred female mice over male mice. The authors concluded that serotonin regulates sexual preference in mammals.
