Abstract:		"Pheromones could promote hormone secretions and regulate sexual behavior. It was unclear whether multiparous pheromone could induce variations in puberty. The aim was to ascertain whether pheromone in urine of multiparous females induced central precocious puberty (CPP) in juvenile C57BL/6J females. The precocious puberty was examined by vaginal smear, lordosis reaction, HE stain, and ELISA analysis. Results suggested that the first vaginal opening and the first estrus were significantly earlier. The time interval of the first vaginal opening and estrus was significantly shortened. It was interesting that the first estrus was significantly correlated with the first vaginal opening and the time interval of the first estrus. In the first estrus, female lordosis reaction, the number of mature follicles, and the weight of the ovary and uterus significantly increased. The level of luteinizing hormones also significantly increased. Thus, multiparous pheromone can regulate sex hormone to induce CPP in juvenile C57BL/6J females"
