Male odors that influence the preference of female mice: roles of urinary and preputial factors. 1988

Female mice preferred to investigate the odor of normal male urine to that of either castrated or preputialectomized male urine. Females showed no particular preferences in two-choice tests among castrated, castrated-preputialectomized and preputialectomized male urine. These results suggest that both urinary and preputial factors of males are involved in female attraction. In an experiment with urine mixtures, females preferred a mixture of urine from preputialectomized males and castrated males to a mixture of urine from preputialectomized males and castrated-preputialectomized males. This strongly suggests that the urinary factor is androgen-dependent, while the preputial factor is possibly androgen-independent. Further experiments demonstrated the possibility that the preputial odorous factor involved in female attraction is increased or newly formed after excretion of the secretion.
