Abstract: | "The effects of donor age on the effectiveness of puberty-influencing urinary chemosignals in wild house mice was tested in a series of 3 experiments. The chemosignal from male mice that accelerates puberty was present in the urine from about the time of puberty and throughout the normal lifespan, but declined about 1 year of age. Oestrous females released a substance in their urine that accelerates puberty in young females. This substance remained effective from first oestrus until over 1 year of age, although older females were in oestrus less frequently than younger mice. Females that are pregnant or lactating released a puberty-accelerating substance in their urine regardless of age. Production and release of the puberty-delaying chemosignal by grouped females was initiated before puberty and continued throughout the lifespan of the mouse" |
