The examination of urethral smears of women with different contraceptive agents shows the presence -- in 20 p. 100 of cases -- of very high rates of columnar cells compared with reference smears; with these first smears, the superficial columnar cells and bare nuclei in degeneration increase compared with underlying columnar cells. The presence of the columnar cells is followed by disappearance of the clusters of squamous cells and therefore the cytohormonal interpretation of these smears is difficult. The most frequent cellular modifications consist of squamous parakeratosis and squamous or columnar anisocytosis. Some hypothesis are given.
