KembaraXtra-Psychology – Bruce Effect
The Bruce effect refers to a phenomenon observed in mice in which a recently mated female fails to maintain pregnancy when exposed to the scent of an unfamiliar male. The effect is triggered by pheromones present in the urine of the strange male, which disrupt prolactin secretion and prevent implantation of the fertilized ovum. It was first described by British reproductive biologist Hilda Margaret Bruce in 1959. This phenomenon illustrates the powerful role of olfactory cues and pheromonal communication in reproductive biology.P
