Uterine Septum: Diagnosis, Surgery, and Fertility Outcomes | Damien Fertility Partners
A uterine septum is the most common congenital uterine anomaly, affecting approximately 1 in 45 women. Its prevalence rises to roughly 15% among patients with recurrent pregnancy loss — a rate high enough to make uterine evaluation a standard part of any thorough fertility workup, particularly after two or more miscarriages or failed IVF cycles.
Patients who receive this diagnosis typically have two immediate questions: what does it mean for their chances of pregnancy, and whether surgical correction changes those odds. The answer to both is grounded in a substantial body of clinical evidence. Research consistently shows that untreated uterine septa are associated with miscarriage rates of 40–65%, and that hysteroscopic resection significantly reduces that risk — in some cohorts reducing recurrent miscarriage from 10.9% to 2.0% post-surgery.
Damien Fertility Partners has provided reproductive care across New Jersey since 1989, with offices in Shrewsbury (Monmouth County), Newark (Essex County), and Jersey City (Hudson County). Our in-house surgical team performs hysteroscopic septum resection directly — patients are not referred out. Every surgical case is managed by the same ABOG board-certified reproductive endocrinologist who conducts the diagnostic evaluation and oversees the treatment plan.
Uterine Septum
A uterine septum is a band of fibrous tissue that partially or completely divides the uterine cavity. It forms during fetal development when the Müllerian ducts — the structures that fuse to create the uterus — fail to fully reabsorb the central dividing wall. The resulting tissue is typically fibrous and poorly vascularized, which is the core reason it impairs implantation and early pregnancy.
Septa are classified by extent. A partial septum extends partway into the uterine cavity. A complete septum reaches the cervix and fully divides the uterine interior. The degree of division influences both the severity of reproductive impact and the complexity of surgical correction.
A uterine septum differs from a bicornuate uterus, a distinction that matters for diagnosis and treatment. A bicornuate uterus involves a physical indentation of the outer fundal surface, while a septum presents with a normal external uterine contour. Standard 2D ultrasound may not reliably differentiate the two. Accurate classification requires 3D ultrasound or hysteroscopy, and in some cases both.
Reproductive Impact of an Untreated Septum
The primary clinical risks associated with a uterine septum are implantation failure and pregnancy loss. An embryo implanting on or near the septum may not receive adequate blood supply from the underlying tissue, which elevates the risk of early miscarriage. Research has linked untreated septa to miscarriage rates between 40% and 65% — substantially above the general population baseline.
The American Society for Reproductive Medicine addresses uterine anomalies in its clinical guidelines on recurrent pregnancy loss, recognizing uterine septa as a correctable structural factor in patients with two or more pregnancy losses.
Beyond miscarriage, a septum may increase the risk of preterm labor, abnormal fetal positioning, and, in some cases, difficulty conceiving at all. Not every patient with a septum will experience these outcomes — many conceive and carry without complication — but the diagnosis warrants clinical attention when reproductive history includes loss or failed implantation.
Diagnosis: Imaging and Hysteroscopy
Transvaginal ultrasound. This is typically the first imaging step and can raise clinical suspicion for a uterine abnormality. It is insufficient on its own for definitive classification.
3D ultrasound. Three-dimensional ultrasound provides a coronal view of the uterine cavity that 2D imaging cannot, allowing providers to assess both the internal contour and the external fundal shape. This view is critical for distinguishing a septum from a bicornuate uterus before proceeding to surgery.
Hysteroscopy. A hysteroscope — a thin camera inserted through the cervix — provides direct visualization of the uterine cavity. Hysteroscopy is the gold standard for confirming a septum diagnosis and is typically performed as both a diagnostic and surgical procedure in the same setting when a septum is confirmed.
Our team performs all uterine evaluations in-house, including 3D ultrasound and diagnostic hysteroscopy. Patients receive results reviewed by the same physician managing their care — there is no handoff to an outside imaging center or surgical facility.
Hysteroscopic Septum Resection
The standard treatment for a uterine septum is hysteroscopic septum resection (also called hysteroscopic metroplasty). It is a minimally invasive outpatient procedure. A hysteroscope and small surgical instruments are used to remove or trim the fibrous septal tissue, restoring a single unified uterine cavity.
Most patients return home the same day. Mild cramping is the most commonly reported side effect. Full uterine healing typically requires one to three months, after which most physicians clear patients to attempt conception or proceed with embryo transfer.
Our in-house surgical team — including Dr. Nina Seigelstein, who performs minimally invasive gynecologic surgical evaluation — handles these procedures directly. Patients undergoing hysteroscopic resection do not need to be referred to an outside surgical center.
Research Outcomes
Clinical evidence for hysteroscopic septum resection is consistent across multiple study designs. One large retrospective study found miscarriage rates fell from 35.6% before surgery to 14.8% afterward. Recurrent miscarriage dropped from 10.9% to 2.0% in the same cohort. Live birth rates nearly doubled — rising from 17.8% to 36.6% following surgical correction.
Additional data report postoperative pregnancy rates of approximately 42–45% and live birth rates of roughly 36.7%. Individual outcomes vary by age, diagnosis, and whether additional fertility factors are present. Evidence consistently supports septum resection as an intervention that meaningfully improves reproductive outcomes for patients with a confirmed diagnosis and relevant clinical history.
For patients proceeding to IVF after resection, our 2023 SART-reported live-birth rate for women under 35 was 81.8% per new patient, with a 100% elective single-embryo transfer (eSET) rate in that age group. Clinic-to-clinic comparisons should be interpreted with caution due to differences in patient populations. Full outcomes data is available on the SART website and our success rates page.
The Physicians Managing Surgical Care
Dr. Miguel Damien founded the practice in 1989 — originally as East Coast IVF, establishing New Jersey’s first successful IVF program in Monmouth and Ocean County. A Dartmouth Medical School graduate, he completed his OB/GYN residency and REI fellowships at Harvard Medical School and the University of Connecticut. Board-certified in REI by ABOG and fluent in Spanish, he has been named a Castle Connolly Top Doctor in the NY Metro Area six times (2005, 2007, 2008, 2010, 2017, 2018).
Dr. Barry Perlman is an ABOG board-certified REI specialist and Fellow of the American College of Obstetricians and Gynecologists (ACOG). A published researcher on endocrine disruptors and fertility, he has been named a Castle Connolly Top Doctor five times. He joined our practice in 2023 and offers both in-person and virtual consultations.
Dr. Nina Seigelstein performs minimally invasive gynecologic surgical evaluation and procedures in-house. Patients with uterine anomalies are not referred out for surgical care.
IVF After Septum Resection
For patients who do not conceive naturally following surgical correction, IVF remains the next clinical step. Our embryology lab holds accreditation from the College of American Pathologists (CAP), the FDA, and the NJ State Department of Health — all with zero deficiencies. The lab is directed by Klaus Wiemer, PhD, HCLD, with over 40 years of clinical embryology experience and more than 80 peer-reviewed publications.
The lab uses CHLOE by Fairtility, an AI-powered embryo monitoring system integrated into embryoscope time-lapse incubators. CHLOE tracks embryo development continuously and non-invasively, providing real-time data to support embryo selection decisions. For patients with a history of implantation failure, preimplantation genetic testing (PGT-A) — which screens embryos for chromosomal abnormalities before transfer — may also be clinically indicated. Our IVF treatment page provides a full overview of the cycle process.
Frequently Asked Questions
1. Can I get pregnant naturally if I have a uterine septum?
Yes — many women with a uterine septum conceive naturally. However, a septum elevates the risk of miscarriage, failed implantation, and preterm labor. The American Society for Reproductive Medicine includes uterine septum evaluation in its guidelines for patients with recurrent pregnancy loss. If you’ve had two or more miscarriages or failed IVF cycles, a uterine evaluation is a clinically appropriate next step.
2. Is a uterine septum the same as a bicornuate uterus?
No. A bicornuate uterus involves a physical indentation of the outer uterine fundus, while a uterine septum presents with a normal external contour and an internal fibrous division. Standard 2D ultrasound may not reliably distinguish the two — accurate diagnosis requires 3D ultrasound or hysteroscopy, both of which we perform in-house.
3. How much does hysteroscopic septum resection improve pregnancy outcomes?
Evidence consistently shows meaningful improvement. One large retrospective study found miscarriage rates fell from 35.6% to 14.8% after surgery, recurrent miscarriage dropped from 10.9% to 2.0%, and live birth rates nearly doubled — from 17.8% to 36.6%. Individual outcomes vary by age and additional fertility factors; your physician will discuss what the data means for your specific clinical picture.
4. How long does recovery take after hysteroscopic septum resection?
Most patients recover within a few days, with mild cramping as the most common complaint. Full uterine healing typically takes one to three months. Most physicians clear patients to attempt conception after that interval, though timing is individualized based on the extent of the resection and overall clinical picture.
5. Does Damien Fertility Partners perform the surgery on-site?
Yes. Our in-house surgical team — including Dr. Nina Seigelstein — performs hysteroscopic septum resection directly. Patients are not referred to an outside surgical center. This keeps care coordinated under the same team managing your fertility evaluation and treatment plan.
6. What comes next if I don’t conceive after septum resection?
For patients who do not conceive naturally following surgical correction, IVF is typically the next recommended step. Our IVF treatment page outlines the full cycle process. Preimplantation genetic testing (PGT-A) may be indicated for patients with a history of recurrent pregnancy loss. Our CHLOE-equipped embryology lab and CAP-accredited facilities support every stage of that process in-house.
