Pregnancy may result from rape. The rate varies between settings and depends particularly on the extent to which non-barrier contraceptives are being used. A study of adolescents in Ethiopia found that among those who reported being raped, 17% became pregnant after the rape, a figure which is similar to the 15–18% reported by rape crisis centres in Mexico. A longitudinal study in the United States of over 4000 women followed for 3 years found that the national rape related pregnancy rate was 5.0% per rape among victims aged 12–45 years, producing over 32,000 pregnancies nationally among women from rape each year. Experience of coerced sex at an early age reduces a woman’s ability to see her sexuality as something over which she has control.
