After one ectopic pregnancy, the chance of it happening again ranges from 10% to 27%, depending on the underlying cause, how the first one was treated, and overall tubal health. That’s a meaningful increase over the general population risk of about 2%, but it also means the majority of women who try again will have a normal pregnancy.
How Recurrence Risk Compares to the General Population
Ectopic pregnancy occurs in roughly 2% of all pregnancies. Once you’ve had one, your risk of a second jumps to somewhere between 10% and 20% in most estimates, with some studies placing the upper bound closer to 27%. The wide range reflects how much individual factors matter: a woman whose ectopic was caused by a one-time event (like an early infection that’s since been treated) faces different odds than someone with chronic tubal damage.
These numbers can feel alarming, but it’s worth flipping them around. Even at the high end, roughly 3 out of 4 subsequent pregnancies will implant normally. At the low end, 9 out of 10 will.
What Happens Inside the Fallopian Tube
The inner lining of the fallopian tubes is covered in tiny, hair-like structures called cilia. Their job is to sweep the fertilized egg toward the uterus in the days after ovulation. When the cilia are damaged or not beating properly, the egg can stall and implant inside the tube instead.
Research has shown that elevated levels of progesterone can slow or even paralyze these cilia. In lab studies, moderate increases in progesterone reduced ciliary activity to about 63% of normal, and at higher concentrations, 50% to 70% of the cilia stopped moving entirely. Infections (particularly chlamydia), prior pelvic surgery, and endometriosis can also cause scarring or inflammation that narrows the tube or disrupts the lining. If the underlying condition that caused the first ectopic pregnancy is still present, recurrence becomes more likely.
How Treatment of the First Ectopic Affects Your Odds
There are two main surgical approaches after an ectopic pregnancy: removing the entire affected tube, or making an incision to remove the pregnancy while leaving the tube intact. The tube-sparing approach carries a recurrence rate of about 10.9%, though this difference compared to full tube removal hasn’t proven statistically significant in meta-analyses. Keeping the tube does preserve a natural pathway for future conception, which matters if the other tube is damaged or absent.
The choice between these two options is one of the most important decisions affecting both your fertility and your recurrence risk, and it depends heavily on the health of your other tube and your reproductive plans.
The Risk of a Third Ectopic After Two
For women who have had two ectopic pregnancies, the risk of a third depends dramatically on how the second one was managed. When the second ectopic was treated with medication or surgery, the rate of a third ectopic was 18.2% and 13.8%, respectively. But when the second ectopic resolved on its own without intervention (expectant management), the risk of a third climbed to 50%.
The pattern was even more striking when both ectopics occurred in the same tube. In those cases, active treatment brought the recurrence rate to about 25.7%, while expectant management was associated with a 60% chance of yet another ectopic. This strongly suggests that leaving a repeat ectopic untreated can allow persistent tubal damage to worsen.
IVF as a Way to Bypass Tubal Risk
In vitro fertilization (IVF) places the embryo directly into the uterus, skipping the fallopian tubes altogether. For women with a history of recurrent ectopic pregnancies, IVF brings the ectopic rate back down to about 2.4%, which is essentially the same as the 2.1% rate seen in women with no ectopic history at all.
Interestingly, women with just one prior ectopic who underwent IVF still had a 6.8% ectopic rate. The likely explanation is that many women who’ve had only a single ectopic still have a partially functioning but damaged tube, and an embryo transferred to the uterus can occasionally migrate into that tube. Women with recurrent ectopics are more likely to have had both tubes removed or fully treated, leaving no tubal pathway for the embryo to wander into.
Within IVF cycles, the type of prior surgery also mattered. Among women with a single prior ectopic, those who had undergone tube-sparing surgery had an 8.4% ectopic rate with IVF, compared to 6.2% for those whose tube was removed. For women with recurrent ectopics, the rates were lower overall: 4.4% after tube-sparing surgery and 2.3% after tube removal.
Fertility Outlook After an Ectopic Pregnancy
The broader picture for future fertility is more reassuring than many people expect. Between 60% and 70% of women become pregnant within two years of treatment for an ectopic pregnancy. Live birth rates range from about 50% to 65%, with some estimates reaching as high as 80% for women without other underlying fertility issues. These numbers come from large cohorts of 300 to 2,000 women across North America and Europe.
The variability in outcomes comes down to tubal health, age, the treatment approach used, and whether there are additional fertility factors at play. Women who retain at least one healthy tube generally have the best chances of conceiving naturally. For those with significant tubal damage on both sides, IVF offers a reliable alternative that effectively neutralizes the elevated ectopic risk.
Early Monitoring in Your Next Pregnancy
If you become pregnant after a prior ectopic, your care team will typically want to confirm the pregnancy’s location early, usually through a combination of blood hormone level checks and an early ultrasound around six weeks. The goal is to verify that the pregnancy is developing inside the uterus before it would cause symptoms if it were ectopic. Knowing your history, most providers will schedule these checks proactively rather than waiting for you to report symptoms.
Symptoms to be aware of in early pregnancy include one-sided pelvic pain, vaginal bleeding, and shoulder tip pain (which can signal internal bleeding). These don’t automatically mean another ectopic, but they do warrant prompt evaluation. The earlier an ectopic is caught, the more treatment options are available and the better the outcome for preserving future fertility.
