Abstract:		"Female rats were exposed to odors from females that went through a birth cycle of pregnancy, birth and lactation. The estrous cycle was shortened by odors from pregnant rats and lengthened by odors from lactating rats and their pups. Changes in estrous cycle length were accompanied by changes in the length of the luteal phase (metestrus-early diestrus). A log survivor plot demonstrated that variation in cycle length was the result of different rates of ovulation within the population under each condition. Neither pregnancy nor lactation odors affected the intensity or timing of the lordosis reflex. These odors could modulate fertility and coordinate birth cycles within a group of rats"
