31 women (average age, 26 years) were administered a modified low dosage gestagen contraceptive, containing .3 of norethisterone for an average period of 10.6 months. Changes in the ultrastructure of the endometrium were studied throughout this period. Changes in both parts of the ultrastructure, the fibrose and epithelial parts, were revealed in comparison to material taken before use of the preparation. Changes in the stromata cells were particularly of a gestagenic character. Epithelial cells also demonstrated a particularly gestagenic stimulation.
