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… Expand
Repeated medical abortions and the risk of preterm birth in the subsequent pregnancy
TLDR
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. Expand
PREGNANCY OUTCOME FOLLOWING ABORTION
The previous two or three induced were spontaneous abortion will carry a risk of preterm, ectopic pregnancy. This is to study is to evaluate the outcome of pregnancy with history of previousExpand
Is induced abortion a risk factor in subsequent pregnancy?
TLDR
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. Expand
Authors’ reply
We showed that medical abortion has no additional short term adverse events or complications in adolescents compared with adults. Thus medical abortion can be used as an alternative to surgicalExpand
Teen Pregnancy: Are Pregnancies following an Elective Termination Associated with Increased Risk for Adverse Perinatal Outcomes?
TLDR
Having a prior abortion may improve the health of a pregnancy though adverse outcomes do not differ between the 2 groups, compared with adolescent women who had just delivered and did not have a priorabortion. Expand
Immediate complications and subsequent reproductive outcome after medical abortion: hospital based cross sectional study
TLDR
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. Expand
Medical termination of pregnancy during the second versus the first trimester and its effects on subsequent pregnancy.
TLDR
Second-trimester MTOP among primigravid women did not increase the risks of preterm birth, low birth weight, SGA infants or placental complications in subsequent pregnancy compared with first- trimesterMTOP, and the data are of value when counseling women undergoing second- Trimester TOP. Expand
Is induced abortion with misoprostol a risk factor for late abortion or preterm delivery in subsequent pregnancies?
TLDR
Results provide some reassurance that induced abortion with misoprostol during the first or second trimester of pregnancy is safe for subsequent pregnancies. Expand
Frequency and Risk Factors for Repeat Abortions After Surgical Compared With Medical Termination of Pregnancy
TLDR
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. Expand
Mifepristone-induced abortion and vaginal bleeding in subsequent pregnancy.
TLDR
One previous mifepristone-induced abortion increased the risk of vaginal bleeding in early gestation period of subsequent pregnancy compared with no abortion, especially if abortion occurred before 7 weeks of gestation and was followed by a curettage or complications. Expand

Induced abortion and low birthweight in the following pregnancy.
TLDR
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. Expand
Induced abortion and risk of subsequent miscarriage.
TLDR
Induced abortion by vacuum aspiration is associated with an increased risk of first-trimester miscarriage in the subsequent pregnancy. Expand
Risk of ectopic pregnancy and previous induced abortion.
TLDR
It is suggested that induced abortion may be a risk factor for ectopicregnancy for women with no previous ectopic pregnancy, particularly in the case of women who have had several induced abortions. Expand
Risk of spontaneous abortion following induced abortion is only increased with short interpregnancy interval.
TLDR
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. Expand
Induced abortions and risk of ectopic pregnancy.
TLDR
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. Expand
Induced abortion and subsequent pregnancy duration.
TLDR
The study showed an increase in preterm and post-term pregnancies after induced abortions, whereas increased risk of preterm delivery was seen mainly when interpregnancy intervals were longer than 12 months. Expand

TLDR
A pregnancy-based cohort study in Shanghai, China with recruitment from 15 general hospitals from November 1993 to March 1998 found that previous first trimester induced abortion did not significantly increase the risk of low birth weight or preterm birth. Expand
The effect of pregnancy termination on future reproduction.
TLDR
In conclusion, except for the association between pregnancies following dilatation and evacuation procedures and premature delivery and low birthweight, no significantly increased risk of adverse reproductive health has been observed following induced abortion. Expand
The Relation Between Induced Abortion and Ectopic Pregnancy
TLDR
There is no evidence that having one or more induced abortions increases a woman's risk of having an ectopic pregnancy, and the odds ratio remained the same after adjusting for selected confounding variables. Expand
Mifepristone-induced early abortion and outcome of subsequent wanted pregnancy.
TLDR
It is suggested that one early abortion induced by mifepristone in nulliparous women has no adverse effects on the outcome of a subsequent pregnancy. Expand
