BACKGROUND The long-term safety of surgical abortion in the first trimester is well established. Despite the increasing use of medical abortion (abortion by means of medication), limited information is available regarding the effects of this procedure on subsequent pregnancies. METHODS We identified all women living in Denmark who had undergone an abortion for nonmedical reasons between 1999 and 2004 and obtained information regarding subsequent pregnancies from national registries. Risks of…

Repeated medical abortions and the risk of preterm birth in the subsequent pregnancy

A history of multiple first trimester mifepristone-induced abortions is not associated with a higher risk of preterm delivery among singleton births in the first subsequent pregnancy.

PREGNANCY OUTCOME FOLLOWING ABORTION

The risk of caesarean was found to be increased in women with previous two or three spontaneous abortions exposing the women to the morbidity associated with the C-section.

Is induced abortion a risk factor in subsequent pregnancy?

The rate of preterm births increases with the number of preceding abortions and symptoms associated with prematurity are more common, and the rate of small-for-gestational-age newborns was not affected.

Authors’ reply

It is shown that medical abortion has no additional short term adverse events or complications in adolescents compared with adults, and offering a choice of medical or surgical abortion is not likely to increase the risk of preterm delivery in subsequent pregnancies.

Immediate complications and subsequent reproductive outcome after medical abortion: hospital based cross sectional study

Medical abortion using Mifepristone and Misoprostol is a reliable and safe method of termination of early pregnancy (up to 7 weeks period of gestation) and these findings are relevant while counseling patients for medical abortion.

Is induced abortion with misoprostol a risk factor for late abortion or preterm delivery in subsequent pregnancies?

Frequency and Risk Factors for Repeat Abortions After Surgical Compared With Medical Termination of Pregnancy

The risk of repeat abortion is associated with various sociodemographic characteristics, and decreased with age, among women living in rural areas, and when intrauterine devices or sterilization were planned for future contraception.

Induced abortion and low birthweight in the following pregnancy.

A positive association between one or more first trimester induced abortions and the risk of low birthweight in subsequent singleton term live births when the interpregnancy interval is longer than 6 months is suggested.

Induced abortion and risk of subsequent miscarriage.

Induced abortion by vacuum aspiration is associated with an increased risk of first-trimester miscarriage in the subsequent pregnancy.

Risk of spontaneous abortion following induced abortion is only increased with short interpregnancy interval.

Overall the study did not show an increased risk of spontaneous abortion following one or more induced abortions, except for women with a short interpregnancy interval between an induced abortion and a subsequent pregnancy.

An increased risk of ectopic pregnancy after induced abortion is shown in this study, using data from a case-control study conducted in Milan, Italy.

Mifepristone-induced early abortion and outcome of subsequent wanted pregnancy.

It is suggested that one early abortion induced by mifepristone in nulliparous women has no adverse effects on the outcome of a subsequent pregnancy.

Induced Abortion as a Risk Factor for Subsequent Fetal Loss

A case‐control study with 331 cases of first spontaneous abortion and 993 controls with no previous spontaneousabortion and a normal pregnancy at the same period of pregnancy reports the relation between past induced abortions and subsequent fetal loss is still unclear.
