[The effect of urine from castrated male or female guinea pigs and rats on the estrous cycle of guinea pigs and rats, respectively]. 1976

L Jesel, and D Chateau, and C Aron

A 24-hour reduced cycle duration was observed in 5-day cyclic female rats exposed to the odor of urine from male or female castrated rats. A decrease in the duration of the period of vaginal closure, ranging from 2 to 5 days, was observed in female guinea pigs exposed to the odor of urine from male or female castrated guinea pigs. The pheromonal activity of urine in both species was concluded to be no dependent upon the gonadal function.
