La hormona es la prolactina, que al parecer estimula el sentido del olfato. Los científicos han observado que en las primeras fases de la gestación y poco después del parto, las hembras de ratón presentan nuevas células en el centro cerebral del olfato, el bulbo elfatorio. Los autores creen que este incremento se deba a la prolactina, y dado que las hembras de los mamíferos utilizan el olfato para reconocer a sus crías, consideran que la hormona tiene un papel importante en las relaciones afectivas.
Pero también se ha visto que desempeña un papel importante en el orgasmo femenino y masculino, y se ha comprobado que inyectar a ratones machos y hembras infusiones de prolactina provocan un aumento de células en el bulbo olfatorio.
