Sex pheromones are not always attractive: changes induced by learning and illness in mice [PDF]
, 2014 A male-specific major urinary protein named darcin is attractive to female mice, Mus musculus, stimulates a learned attraction to volatile components of a male's urinary odour and induces spatial learning. In this article we show that darcin also induces
