The Vandenbergh effect is a phenomenon reported in 1975, in which an early induction of the first estrous cycle in prepubertal female mice as a result of exposure to the pheromone-laden urine of a sexually mature (dominant) male mouse. Physiologically, the exposure to male urine induces the release of GnRH, which provokes the first estrus. The Vandenbergh effect has also been seen with exposure to adult female mice. When an immature female mouse is exposed to the urine of mature female mouse, estrus is delayed in the prepubertal female. In this situation, GnRH is inhibited and therefore delays puberty in the juvenile female mouse.[1]
