Dr Moodie I recommend that you and priveleged others who think unintended pregnancy and abortion are merely matters of 'safe sex', health education and STIs do more homework. Contraceptive failure is estimated to conribute to over 30% of unintended pregnancies. An ABS report noted that in reports of domestic violence over 40% of women were pregnant at the time. There is a strong association between unintended pregnancy and violence against women, especially in young age groups.
