Data on the amount of uroepithelial squamous cells released into the fluid of urethral expulsions were obtained in a 37-year-old multipara by daily five consecutive repeated applications of the digital stimulation technique, carried out over the period of one and a half of her menstrual cycle. During the secretory phase of the cycle the rate of the cellular component was far higher than during the proliferative phase. These quantitative biometrically analysed data provide a complementary picture to the qualitative cytological changes of uroepithelial squamous cells occurring during the menstrual cycle that have been reported so far.
