Ever since induced abortion was legalized in the United States, there has been a running controversy over whether induced abortion affects subsequent childbearing; for example, it has been claimed that women who terminate a pregnancy are at a greater risk of miscarrying a subsequent pregnancy or of having a low-birth-weight baby. Ten studies of the later impact of first-trimester induced abortion by vacuum aspiration (the dominant method in the United States) are examined here; they find that compared with women who carry their first pregnancy to term, women whose first pregnancy ends in induced abortion have no greater risk of bearing low-birth-weight babies, delivering prematurely or suffering spontaneous abortions in subsequent pregnancies. ⋯ In addition, some evidence from other studies links dilatation and curettage (D&C) procedures with later infertility, but most studies have found no such association. No definite conclusions can be reached about the impact of multiple induced abortions, since the results of 13 different epidemiologic studies are almost evenly divided between those that show no effect and those reporting related reproductive problems.
