Getting pregnant without fallopian tubes is extremely unlikely to happen naturally, but it is possible through in vitro fertilization (IVF). The fallopian tubes are where egg meets sperm, so removing both eliminates the natural path to conception. IVF bypasses the tubes entirely by fertilizing eggs outside the body and placing embryos directly into the uterus.
Why Fallopian Tubes Matter for Natural Conception
Your fallopian tubes are the bridge between your ovaries and your uterus. Each month, an egg leaves one ovary and travels through the tube, where it can meet sperm and become fertilized. The fertilized egg then continues down into the uterus to implant. Without this passageway, sperm and egg have no way to find each other inside your body.
If only one tube has been removed (a unilateral salpingectomy), you can still get pregnant naturally as long as the remaining tube is functioning. The single tube can even pick up eggs released from the ovary on the opposite side in some cases. But if both tubes are gone, natural conception becomes nearly impossible.
Rare Cases of Natural Pregnancy After Tube Removal
A systematic review searching nearly 2,000 published studies found only four documented cases of spontaneous pregnancy after both fallopian tubes were completely removed. All four pregnancies implanted normally inside the uterus, and all occurred in women whose tubes had been removed for medical reasons like infection or ectopic pregnancy, not for sterilization. No cases of spontaneous pregnancy were found in women who had both tubes removed specifically as a form of birth control.
The handful of cases that exist likely involved a tiny remnant of tubal tissue near the uterus, creating just enough of a channel for sperm to reach an egg. But with odds this low, doctors treat bilateral salpingectomy as essentially permanent. If you’ve had both tubes removed and want to become pregnant, IVF is the realistic path forward.
How IVF Works Without Fallopian Tubes
IVF was originally developed for exactly this situation. The procedure collects eggs directly from your ovaries, fertilizes them with sperm in a lab, and then transfers the resulting embryo into your uterus. The fallopian tubes are never part of the equation.
Before starting a cycle, you’ll go through screening that typically includes ovarian reserve testing (to see how many eggs your ovaries can produce), a semen analysis for your partner, infectious disease screening, and a uterine exam. Once these are complete, a single IVF cycle takes about two to three weeks and follows a predictable sequence:
- Ovarian stimulation: Fertility medications prompt your ovaries to produce multiple mature eggs over one to two weeks.
- Egg retrieval: A minor procedure collects eggs from your ovaries, timed about 34 to 36 hours after a final trigger shot.
- Fertilization: Eggs and sperm are combined in a lab dish. In some cases, a single sperm is injected directly into each egg.
- Embryo transfer: Two to six days after retrieval, one or more embryos are placed into your uterus through a thin catheter.
IVF Success Rates After Tube Removal
Having your tubes removed before IVF doesn’t hurt your chances. In fact, it can help. When tubes are removed because they’re damaged or filled with fluid (a condition called hydrosalpinx), IVF outcomes actually improve. In one clinical trial of 204 patients, the delivery rate was 28.6% for women who had salpingectomy before IVF compared to just 16.3% for those who kept their damaged tubes. Across multiple trials, the ongoing pregnancy rate after tube removal was about 34%, roughly double the rate seen in women who still had their damaged tubes during IVF.
This happens because fluid from damaged tubes can leak into the uterus and interfere with embryo implantation. Removing the tubes eliminates that problem. If your tubes were removed because they were healthy and you chose sterilization, your IVF odds depend on the same factors as anyone else: your age, egg quality, and overall reproductive health.
Ectopic Pregnancy Risk Still Exists
Even without fallopian tubes, a small risk of ectopic pregnancy remains during IVF. A tiny section of each tube, the part embedded in the uterine wall, is left behind during surgery. An embryo can occasionally implant in this residual tissue. This type of ectopic pregnancy, called an interstitial pregnancy, is rare in the general population but occurs in roughly 1% of IVF pregnancies. Because this area has a rich blood supply, a pregnancy there carries a higher risk of rupture and serious bleeding, making early monitoring important.
Your fertility clinic will schedule an early ultrasound, typically around six weeks, to confirm the embryo has implanted in the correct location inside the uterus. Symptoms like sharp one-sided pelvic pain or unusual bleeding before that scan should be reported right away.
