A normal pregnancy is not possible after a hysterectomy. Without a uterus, there is no place for a fertilized egg to implant and grow into a baby. However, in extraordinarily rare cases, an ectopic pregnancy can occur after a hysterectomy if the ovaries were left in place. Only about 108 such cases have ever been documented in the entire medical literature, making this one of the rarest events in reproductive medicine.
Why Pregnancy Can’t Happen Normally
A hysterectomy removes the uterus, which is where a pregnancy develops. Without it, even if your ovaries still release eggs each month, there is no womb lining for an embryo to attach to and no protected space for a fetus to grow. The surgery also disconnects the path that sperm would normally travel from the vagina, through the cervix, and into the uterus to reach an egg.
If your ovaries were also removed during the surgery (a procedure called an oophorectomy), your body stops producing eggs entirely. This eliminates any theoretical possibility of conception. If your ovaries were preserved, they may continue to release eggs on a roughly monthly cycle, but those eggs are simply reabsorbed by the body with nowhere to go.
The Rare Exception: Ectopic Pregnancy
In a very small number of documented cases, sperm have found a way into the abdominal cavity after a hysterectomy and fertilized an egg released by a remaining ovary. This results in an ectopic pregnancy, where the embryo implants somewhere outside the uterus, typically on a remaining fallopian tube, on abdominal tissue, or on the ovary itself. These pregnancies are never viable. They cannot produce a baby and are considered medical emergencies because of the risk of life-threatening internal bleeding.
How does sperm get through? In some cases, a small channel forms between the top of the vagina (where it was surgically closed) and the abdominal cavity. This can happen through a fistula, which is a tiny tunnel of tissue that develops during healing. In other cases, the cervical remnant left behind after a partial hysterectomy retains an open passage, allowing sperm to pass through.
Supracervical vs. Total Hysterectomy
The type of hysterectomy you had matters when it comes to this rare risk. A supracervical (also called partial or subtotal) hysterectomy removes the upper portion of the uterus but leaves the cervix in place. A total hysterectomy removes both the uterus and cervix.
Of the 108 documented post-hysterectomy ectopic pregnancies, 34 occurred in patients who had a supracervical hysterectomy and 74 occurred after a total hysterectomy. While more total cases exist overall (likely because total hysterectomies are performed far more often), the supracervical procedure carries a distinct concern. During laparoscopic supracervical hysterectomy, surgeons typically cauterize the remaining cervical canal to seal it shut. Research has shown this technique sometimes fails to fully close the canal, leaving a potential pathway for sperm. Cases have been documented where the cervical canal remained open despite cauterization.
With total hysterectomy, the risk is even lower because the vaginal cuff is typically sealed and separated from the pelvic cavity by additional tissue layers. Still, late-developing fistulas can form, which explains why ectopic pregnancies have been reported even years after a total hysterectomy. Notably, ectopic pregnancies after supracervical hysterectomy are more likely to occur long after the surgery rather than in the period immediately surrounding it.
Warning Signs to Recognize
Because most people (and even some doctors) assume pregnancy is impossible after a hysterectomy, ectopic pregnancies in this situation are often diagnosed late. If you have had a hysterectomy but still have one or both ovaries, be aware that unexplained abdominal or pelvic pain could, in very rare circumstances, be related to an ectopic pregnancy. Other signs include vaginal bleeding, dizziness, shoulder pain, or feeling faint.
A positive pregnancy test after a hysterectomy should always be taken seriously and evaluated immediately. These pregnancies can rupture blood vessels and cause dangerous internal bleeding. Early detection through blood tests and imaging makes treatment much safer.
Options for Having a Biological Child
If you have had a hysterectomy but your ovaries are intact and functioning, you still have biological eggs. This means you can potentially have a genetically related child through gestational surrogacy. In this process, your ovaries are stimulated to produce eggs, which are retrieved, fertilized through IVF, and the resulting embryos are transferred to a surrogate who carries the pregnancy. Even in complex situations where ovaries have been moved to a different position in the body during cancer treatment, successful egg retrieval and surrogacy have been documented.
If your ovaries were removed along with your uterus, using donor eggs with a gestational surrogate is another path to parenthood. The growing availability of surrogacy programs and egg donation has made biological family building after hysterectomy more accessible than it was even a decade ago, though costs and legal considerations vary significantly by location.
