Pheromone exposure decreased offspring death and chromosomal abnormalities by twofold.](https://www.sciencedaily.com/releases/2022/05/220519132743.htm) > Exposure of female roundworms to male pheromones slowed down the aging of the females' egg cells, resulting in healthier offspring. > > Not only did the exposure decrease embryonic death by more than twofold, it also decreased chromosomal abnormalities in surviving offspring by more than twofold. Under the microscope, egg cells also looked younger and healthier, rather than tiny and misshapen, which is common with aging. > > When conditions are not conducive to reproduction, female animals will spend resources and energy maintaining their overall body health, including muscles, neurons, intestines and other nonreproductive organs. Sensing male pheromones triggers downstream signaling from the nervous system to the rest of the body, causing the female animals to shift their energy and resources to increasing reproductive health instead. The result? Better eggs but faster decay of the body.
