Few studies have been done to see if an abortion affects the woman psychologically, or mentally. Those that have been done give contradictory results. One study looked at 13.000 women who had become pregnant even though they did not want to. The study found that having an induced abortion does not increase the risk of getting mental health problems; the group that was compared were women who also did not want to have a baby, but who did not have an abortion. Other studies showed similar results: women who had an abortion did better in school or at work after the abortion. Another study showed that women who had an abortion had a higher self-esteem and felt better than those who did not.
