An abnormally shaped uterus is something you are born with — but it usually announces itself years later, in ways that are easy to blame on yourself. Do any of these fit?
Have you had more than one miscarriage and been told “it’s just bad luck” without your uterus ever being imaged properly?
Did your periods never start, or start late with unusual pain, in your teens?
Do you have severe one-sided period pain that painkillers barely touch?
Were you told during a scan or delivery that your uterus is “heart-shaped“, “double” or “small” — and never given a follow-up plan?
Has a tampon never worked properly, or intercourse always been difficult, and you were embarrassed to ask why?
Are you carrying a quiet fear that your body “can’t hold a pregnancy“?
These concerns are common — and more measurable than most women are told. Congenital uterine anomalies are found in about 5.5% of all women, rising to 8% of women with infertility, 13.3% of women with a history of miscarriage, and 24.5% of women with both miscarriage and infertility (Chan et al., Human Reproduction Update 2011). In a small Indian series of women with recurrent pregnancy loss undergoing hysteroscopy, a uterine septum was the commonest finding, seen in 25% (Habib et al., IJRCOG 2019, n=40).
The good news is that the anomalies most strongly linked to miscarriage are exactly the ones a hysteroscope can reach, and evaluation is simple and outpatient. Dr. Dimple Doshi has 100+ patients treated for congenital uterine malformations [clinic to confirm], alongside a much larger septate-uterus practice, and most evaluations end with reassurance rather than surgery.
Global Stats: 5.5% — women overall with a uterine anomaly · 24.5% — women with miscarriage + infertility (both Chan 2011) · 25% — septum rate in one Indian recurrent-loss hysteroscopy series (IJRCOG 2019, n=40) · 100+ patients treated for congenital uterine malformations.
A uterine malformation — or congenital uterine anomaly — is a difference in the shape of the uterus present from birth, formed when the two müllerian ducts that build the uterus fuse incompletely in the womb. Many cause no problems at all; others contribute to painful or absent periods, miscarriage, preterm birth or infertility. Several can be treated — some with a short hysteroscopic day-care procedure.
Common examples: septate uterus (a wall dividing the cavity), bicornuate (“heart-shaped”) uterus, unicornuate (one-sided) uterus, uterus didelphys (double uterus), and müllerian agenesis (MRKH — absent or undeveloped uterus and vagina).
Many are silent — found only during a fertility work-up, a scan in pregnancy, or evaluation of recurrent pregnancy loss.
Not every anomaly needs surgery — treatment is chosen by anomaly type, symptoms and reproductive plans, not by the scan picture alone.

Uterine malformations are classified by the ASRM Müllerian Anomalies Classification (2021), which replaced the older “Class 1–6” system many websites still show. It groups anomalies into nine categories, from a completely absent uterus to complex combined anomalies. Knowing the exact type matters, because each carries a different outlook and only some benefit from treatment.
Müllerian agenesis (MRKH syndrome) — the uterus and most of the vagina are absent or undeveloped; periods never start. Ovaries are normal, so genetic motherhood is possible via surrogacy/IVF.
Cervical agenesis — the uterus forms but its cervix does not; a rare, complex anomaly.
Unicornuate uterus — one-sided (“banana-shaped”) uterus from one duct only; often with a small rudimentary horn on the other side, which can trap menstrual blood or, rarely, a pregnancy.
Uterus didelphys — a complete double uterus, usually with two cervices and often a vaginal partition.
Bicornuate uterus — a heart-shaped uterus with an indented top, from incomplete outer fusion.
Septate uterus — the outside looks normal but a fibrous wall divides the cavity; the anomaly most consistently associated with miscarriage. See septate uterus.
Longitudinal vaginal septum — a lengthwise vaginal wall, often alongside didelphys; can make tampons and intercourse difficult.
Transverse vaginal septum — a crosswise block in the vagina; presents in teens with absent visible periods but monthly pain.
Complex anomalies — combinations of the above, planned case by case.
What about the “arcuate uterus” and “T-shaped uterus” you may have read about? An arcuate uterus — a shallow dimple at the top of the cavity — is now regarded as a variant of normal, not a malformation needing correction. A T-shaped cavity is uncommon and its correction is offered only in selected fertility cases.
Kidneys are checked too — the kidneys develop alongside the müllerian ducts, and ASRM strongly recommends renal imaging with müllerian agenesis and one-sided obstructed anomalies (ASRM MAC 2021).
Most uterine malformations cause either no symptoms or problems in three areas: periods, pregnancy and intercourse. The pattern depends on whether the anomaly obstructs menstrual flow, splits the cavity, or replaces the uterus altogether. Many women discover theirs only on a scan — which is itself a reason for a structured evaluation rather than alarm.
Period problems — periods that never start (see absent periods), severe period pain (especially one-sided, from an obstructed horn), or irregular bleeding.
Pregnancy problems — recurrent miscarriage, second-trimester loss, breech position, preterm birth, or difficulty conceiving.
Intercourse or tampon difficulty — from a vaginal septum.
No symptoms at all — an incidental finding; not every anomaly needs anything more than documentation.
In teenagers — cyclical monthly pain without visible periods is a classic obstructed-anomaly story; evaluation belongs with adolescent gynaecology.
Seek immediate care — go to an emergency department or call Vardaan Hospital now — if: a teenager has severe cyclical lower-abdominal pain with absent or scant periods and a growing lower-abdominal mass (an obstructed anomaly with trapped blood) · a woman with a known unicornuate uterus or rudimentary horn has a positive pregnancy test with severe abdominal pain or fainting (possible horn pregnancy — a rupture risk handled like an ectopic pregnancy) · any pregnant woman with a known anomaly has bleeding, leaking fluid or regular pains before 37 weeks.
A uterine malformation is diagnosed with imaging that shows both the inside and the outside of the uterus — the outer contour is what separates a septate from a bicornuate uterus, and the two are managed differently. Evaluation is stepwise: examination, ultrasound (ideally 3D), MRI for complex cases, and hysteroscopy with laparoscopy when surgery is planned.
Physical examination — including the vaginal canal (septa are found by examination alone in many cases).
Ultrasound, preferably 3D — the workhorse test: maps the cavity and the outer contour in one sitting.
Pelvic MRI — for complex, obstructed or agenesis cases and pre-surgical planning.
HSG (hysterosalpingography) — outlines the cavity and tubes during a fertility work-up, but cannot see the outer contour, so it never stands alone.
Hysteroscopy — direct view of the cavity, as an office procedure without admission.
Diagnostic laparoscopy — shows the outer shape directly; combined with hysteroscopy in one anaesthetic when correction is planned in the same sitting.
Kidney imaging — ultrasound of the renal tract whenever agenesis or a one-sided obstructed anomaly is found (ASRM MAC 2021).
Treatment of a uterine malformation depends on the type and on what it is actually causing. A septum can be divided hysteroscopically in a day-care procedure; obstructing vaginal septa are excised; MRKH is managed with vaginal creation when the woman chooses; and several anomalies — bicornuate, didelphys, unicornuate, arcuate — are usually not operated on at all, but managed through pregnancy care.
Septate uterus — hysteroscopic septal resection: the wall is divided through the cervix, no cuts, no stitches, same-day discharge, short recovery. Dr. Doshi’s practice includes 3,000+ patients treated for septate uterus [clinic to confirm] — details on the septate uterus page.
The honest trade-off most pages omit: the randomised TRUST trial (80 women, Hum Reprod 2021) found no improvement in live birth after septum resection (31% vs 35% with no surgery) and advised against routine resection. Careful case selection — rather than operating on every septum — is therefore the standard Dr. Doshi applies. [REVIEWER: state your selection criteria here in one or two sentences — e.g. recurrent second-trimester loss, septum size, prior obstetric history — do not publish without this.]
Transverse or longitudinal vaginal septum — surgical excision, relieving obstruction and making intercourse and delivery possible.
Obstructed rudimentary horn — 3D laparoscopic removal of the horn to end trapped-blood pain and remove the horn-pregnancy risk.
T-shaped uterus — hysteroscopic expansion metroplasty in selected fertility cases only; evidence is limited and this is decided case by case.
Usually no surgery: bicornuate, didelphys and unicornuate uteri are not “repaired” as a routine — the operation (abdominal metroplasty) is major, rarely justified, and these anomalies are instead managed with attentive pregnancy care. Arcuate uterus needs no treatment at all.
Davydov vaginoplasty is a laparoscopic operation that creates a functional vagina for women with MRKH syndrome, in whom the uterus and upper vagina did not develop. The pelvic lining (peritoneum) is mobilised to form the new vaginal canal. It is one option alongside non-surgical dilator programmes, which international practice recommends trying first for most women.
Who it is for — women with müllerian agenesis (MRKH) who want a functional vagina, when a supervised dilator programme has not succeeded or is not acceptable.
How it is done — laparoscopically, with a short hospital stay; a mould and dilation schedule follow while the new canal matures. [REVIEWER: confirm your technique, stay and after-care schedule.]
What it does not change — MRKH does not affect the ovaries; hormones are normal, and genetic children are possible through IVF with surrogacy. Timing of surgery is the woman’s choice, not an emergency.
Emotional support matters — the diagnosis usually arrives in the teens; counselling is part of care, and consultations are private and unhurried.
Yes — most women with a uterine malformation can become pregnant, and many carry without complications. The anomaly type sets the risk: septate uteri raise miscarriage risk, unicornuate and didelphys pregnancies need closer monitoring for preterm birth and breech position, and MRKH requires surrogacy. What changes outcomes is knowing the anomaly before or early in pregnancy.
Septate uterus — the strongest link with miscarriage; whether to divide it first is a counselled decision (see B6), especially with recurrent pregnancy loss.
Bicornuate / didelphys / unicornuate — usually conceive normally; pregnancy is followed as a high-risk pregnancy with cervical-length monitoring for preterm risk and planning for breech, where a C-section delivery may be advised.
After a loss — structured miscarriage management includes imaging the uterus before the next attempt.
Trouble conceiving — anomalies coexist with other factors; a full infertility evaluation avoids blaming the anomaly for everything, and IVF planning accounts for the cavity shape.
For insurance and mediclaim paperwork, congenital uterine malformations are coded under ICD-10 Q51. Indian hospitals and insurers use ICD-10 for diagnosis; American CPT procedure codes sometimes listed online are not used for billing in India.
Q51.0 — Agenesis and aplasia of uterus (includes MRKH)
Q51.1 — Doubling of uterus with doubling of cervix and vagina (didelphys)
Q51.2 — Other doubling of uterus (septate)
Q51.3 — Bicornuate uterus · Q51.4 — Unicornuate uterus · Q51.8 — Other malformations · Q51.9 — Unspecified.
Ans. About 5.5% of women have a congenital uterine anomaly. The figure rises to 8% among women with infertility and 24.5% among women with both miscarriage and infertility (Chan 2011) — which is why imaging the uterus is a standard part of recurrent-loss evaluation.
Ans. Neither anything you did nor, in most cases, inherited. The uterus forms from two ducts fusing before your own birth; a malformation is an accident of that fusion. Most cases are sporadic, and routine genetic testing is not needed for the common anomalies.
Ans. A septate uterus looks normal outside but has an internal wall; a bicornuate uterus has an indented, heart-shaped outer contour. The distinction changes treatment — a septum can be divided hysteroscopically, a bicornuate uterus is not routinely operated — so imaging must show the outer contour (3D ultrasound or MRI).
Ans. No. The randomised TRUST trial found no improvement in live birth after routine septum resection (31% vs 35% without surgery). Resection is now a selected-case decision — discussed individually when losses recur or other factors point to the septum — not an automatic response to the finding.
Ans. An arcuate uterus — a shallow dimple at the top of the cavity — is considered a normal variant in the current ASRM classification. It is not an established cause of miscarriage and does not need correction. If you were offered surgery for an arcuate uterus, a second opinion is reasonable.
Ans. Absent periods with normal breast development can indicate müllerian agenesis (MRKH) or an obstruction such as a transverse vaginal septum — especially if there is monthly pain without bleeding. Both are diagnosed with examination and MRI, and both have effective management. See a gynaecologist rather than waiting.
Ans. Often suspected, yes — but a routine 2D scan can miss or mislabel anomalies. 3D ultrasound shows the cavity and outer contour together and is the preferred first-line test; MRI is added for complex cases. A scan done during pregnancy may be the first clue and deserves a dedicated follow-up scan afterwards.
Ans. Worsening monthly cramps with no visible period, a lower-abdominal mass, or pain that started soon after breast development. Trapped menstrual blood needs timely surgical drainage to relieve pain and protect fertility — this is one situation where waiting is harmful.
Ans. Not automatically. Many women with anomalies deliver vaginally. A C-section is planned for the usual obstetric reasons — breech position (more common with anomalies), a vaginal septum in the way, or previous uterine surgery such as an abdominal metroplasty.
Ans. Most unicornuate pregnancies do well with monitoring for preterm birth and growth. The specific danger is a pregnancy implanting in a rudimentary horn, which can rupture — why the horn is often removed laparoscopically when found, and why early scans matter in every pregnancy with a known anomaly.
Ans. Yes. A functional vagina can be created — first-line with a supervised dilator programme, or surgically (laparoscopic Davydov vaginoplasty). Ovaries are normal in MRKH, so genetic children are possible through IVF with surrogacy. Counselling and unhurried, private consultations are part of treatment.
Ans. After any second miscarriage; if periods never started by 15–16; for severe one-sided period pain; if a scan or delivery note mentioned an unusual uterus shape; or before fertility treatment. Seek emergency care for the situations in the red box above — obstructed monthly pain in a teen, or pregnancy pain with a known horn.
