[Correlation in the guinea pig between the appearance of vaginal leukocyte changes and mating]

The AA. have carried out researches on the cronological relation between leukocytarian flow and male acceptance. They have used colpocitological tests brought on twice a day on 41 female guinea pigs. On the basis of their results the Authors can state that in this species the period of male acceptance is covered within 14 hours every cycle. In about 50% of subjects the period starts with vaginal opening and probably the mating precedes the leukocytarian flow.
