Diet may counteract or substitute for chemical cues that influence sexual maturation. Male California voles, Microtus californicus, for instance, are inhibited in their sexual development by odors from their mothers or unrelated females. This effect is eliminated if the regular diet is enriched with fresh lettuce. In young females, uterus growth is stimulated by the odor of males but, in the absence of males, fresh lettuce added to the diet can accomplish the same effect (Rissman and Johnston, 1986). This can be seen as another case of adaptive redundancy of cues for an important function. 

Exposing young male prairie deer mice, Peromyscus maniculatus, to soiled bedding from adult male conspecifics retards the growth of their testes and seminal vesicles. Male, but not female, urine applied to the nose has the same effect. Removal of the olfactory lobes at the age of 3 weeks blocks this effect (Lawton, 1979). The reproductive development of male California voles, M. californicus, is suppressed hy chemical cues from the mother (Rissman etah, 1984).
