From Christian Post:

Clarke Forsythe, senior counsel at Americans United for Life, told The Christian Post that this study was important for it added to many other studies that had similar results.

“I think this new study is important, not because it alone will shift the debate, but because it adds to a growing body of data,” said Forsythe. “I think it is important because educating the public, and doctors and women on the risks of abortion is critically important.”

According to Forsythe of AUL, there are over 130 studies from the 1960s to the present that have shown a link between preterm birth and abortion.

With the addition of this latest study to the list, Forsythe told CP that he believed the body of evidence weighs against the rationale that was behind the 1973 Supreme Court decision Roe v. Wade.
“Because the risks address both the Supreme Court’s rationale for abortion (that women have come to rely on abortion as a backup to failed contraception) and the myth in public opinion that legal abortion is a ‘necessary evil,'” said Forsythe.
