A new Bowling Green State University study shows women who have an abortion are more likely to suffer from mental health issues.
Researchers found that terminating a pregnancy can double the risk of severe mental health problems.
According to the study, among women, one in 10 of all mental health issues is a result of abortion.
"There are, in fact, some real risks associated with abortion that should be shared with women as they are counseled prior to an abortion," said professor Priscilla Coleman, the author of the study.
The study, published in the British Journal of Psychiatry, was based on the experiences of 877,000 women, 163,831 of whom had had an abortion.
"It is imperative that women are made aware of the real risks of developing mental health problems post-abortion," Philippa Taylor, of Britain's Christian Medical Foundation, told The Daily Telegraph.
"We welcome this rigorous, extensive and most timely research," she said.
