Female mice do not avoid mating with unhealthy males

A male’s attractiveness lies not only in his physical appearance. This is true for people as well as for animals. Scent plays an important role for many creatures when it comes to choosing a mating partner. Female mice show preferences for the scent of healthy males and yet surprisingly they choose unhealthy males just as often as mating partners, scientists report. Mating choice is therefore not based solely on odor.
