Ectopic Pregnancy - What Increases Your Risk
Factors that can increase
your risk of having an
ectopic pregnancy include:1
Medical treatments and procedures that can increase your risk of having an ectopic pregnancy include:
- Previous fallopian tube surgery to treat
infertility or to reverse a
- A tubal ligation failure.
In rare cases when pregnancy happens after a sterilization surgery, there is a
higher-than-usual risk that the pregnancy is ectopic.
progestin-only birth control failure, such as progestin-only pills, or a pregnancy that
happens with an
intrauterine device (IUD) in place.2
- Treatment with
assisted reproductive technology (ART), such as
in vitro fertilization (IVF).2 This may result from the flushing of the fertilized egg into
a damaged fallopian tube after it is transferred to the uterus.
Infection after any kind of surgery done on the uterus or fallopian tubes. This
can lead to scar tissue.
Ectopic pregnancy has been linked to the use of medicine
used to make the ovary release multiple eggs (superovulation). Experts do not yet know whether this
is because many women using it already have fallopian tube damage or because of
the medicine itself.1
If you become pregnant and are at high risk for ectopic pregnancy, you will
be closely watched. Doctors do not always agree about which risk factors are
serious enough to watch closely. But research suggests that risk is serious
enough if you have had a tubal surgery or an ectopic pregnancy before, had DES
exposure before birth, have known fallopian tube problems, or have a pregnancy
with an intrauterine device (IUD) in place.1
