Simultaneous recordings of the intra‐uterine and intra‐vaginal pressures were carried out in 24 women in early pregnancy. At rest the uterine pressure was slightly higher than the vaginal pressure. Body position and physical efforts resulting in increased intra‐abdominal pressure had no essential effect on the utero‐vaginal pressure difference. This would seem to be an important mechanism for protection of the ovum during pregnancy.
