I don't believe this is so, if by "coercion" one means the legal definition of using physical or extreme psychological harm for the purpose of forcing someone to act against their will.

"My husband/boyfriend says he'll leave me if I don't get an abortion" doesn't fit the legal definition of coercion.

However,  "my husband beat the #### out of me and threatened to kill me" if I didn't an abortion -- yes, that's actual coercion.

Given that there are 3000 abortions a day and hardly any reports of actual coercion,  I think the case is weak that women are genuinely forced into having abortions.
