A University of Otago study revealed that sensory cues from the opposite sex, such as smells, can affect aging and health in animals, showing reduced fertility and increased mortality in male mice exposed to female odors. This underscores the significant impact of sensory experiences on long-term health and aging processes.Lead author Associate Professor Mike Garratt, of the Department of Anatomy, says research has previously shown interactions with the opposite sex can speed up aging.
The researchers found males exposed to female olfactory cues, or chemical smell signals, from middle to old age had reduced fertility later in life. Males exposed to female odors in conjunction with mating also showed an increased mortality rate.It is not known why these effects occurred, but Associate Professor Garratt says the results highlight how sensory perception of mates may be an important driver of life-history trade-offs in mammals.
