Abstract
In contrast to unscented stud males, stud males anointed with a commercial perfume failed to protect implantation in food-deprived females. It is suggested that the failure of perfumed stud males to protect pregnancy in their coital partners is due to the masking effect of the perfume on the stud male-originating olfactory cue which stimulates luteotrophic activity in females. The results are also consistent with the view that the newly inseminated female mouse identifies the stud male as an individual through a pheromonal cue and this is involved in the protective effect on implantation in the food-deprived female.
