Sex preference and species specificity of rodent (Mus musculus and Microtus arvalis pheromones.

The behavioural response to the sex pheromones in the externally voided urine of field voles (Microtus arvalis) and laboratory mice (CFLP, CBA strains) although specific for species showed no strain specificity. Bladder urine (free of accessory sex-gland secretions) and the preputial glands of CFLP and CBA mice contain sex attractants. Ether extracts made of blood of male CFLP mice attracted CFLP female mice.
