A study of 576 pregnant women, whose previous pregnancy had been terminated by legally induced abortion, has shown that the rate of pregnancy and delivery complications could not be correlated with the interval between the abortion and the subsequent pregnancy, nor with the gestational age at the time of abortion, nor the number of previous induced abortions. Neither was the abortion technique found to correlate with the frequency of complications in a subsequent pregnancy. It was found, however, that more infants with a birth weight below 2 501 grams were born to women whose cervical canal during abortion had been dilated more than 12 mm, and by women who had been submitted to récurettage. The latter group also demonstrated a higher frequency of retained placenta or placental tissue.
一项针对576名曾因合法人工流产而终止前次妊娠的孕妇的研究表明，妊娠和分娩并发症的发生率与人工流产和随后妊娠之间的间隔时间、人工流产时的孕周以及既往人工流产的次数均无关联。人工流产技术也与随后妊娠并发症的发生率无关。然而，研究发现，人工流产时宫颈管扩张超过12毫米的女性以及接受刮宫术的女性所分娩的出生体重低于2501克的婴儿更多。后一组还表现出胎盘或胎盘组织残留的频率更高。
