Male common marmosets smell female fertility

Males can thus distinguish between cycle phases

Scientists from the University of Leipzig and the Max Planck Institute for Evolutionary Anthropology found that male common marmosets are able to detect the fertile phase of females based on changes in their body odor. Using a combination of chemical analyses and a behavioral test they found that female common marmosets release various substances that produce a specific smell during their fertile phase and that males can perceive these olfactory changes.
