Among 1954 pregnant women who booked before the end of the 14th week of gestation the uterus was retroverted in 220 (11.2%). The incidence of bleeding in early pregnancy and spontaneous abortion was significantly higher in the retroverted group. Only three patients (1.4%) with a retroverted gravid uterus developed acute retention of urine. Patients with retroverted uteri did not have a higher incidence of previous infertility, nor any increase in the incidence of common obstetric abnormalities.
