The goal of treatment
Before walking through the options, it's worth being clear about what treatment is trying to achieve. There are four distinct goals — and understanding each one helps you evaluate the protocol your surgeon proposes.
Treatment is generally recommended for women who have symptoms (absent or reduced periods, pelvic pain, recurrent miscarriage) or fertility goals. For women who are asymptomatic and not trying to conceive, monitoring alone may be appropriate — this is worth discussing with your specialist.
Hysteroscopic adhesiolysis — the main treatment
Hysteroscopic adhesiolysis is the gold standard treatment for intrauterine adhesions. There is no equivalent medical or pharmaceutical alternative — adhesions that are blocking or distorting the cavity must be physically removed.
What it is
A hysteroscope — a thin, lighted telescope — is passed through the cervix into the uterine cavity. The surgeon views the cavity directly on a monitor. Adhesions are then cut, vaporised, or divided under direct vision, gradually opening and restoring the cavity's normal shape.
Surgical techniques
| Instrument | Mechanism | Considerations |
|---|---|---|
| Microscissors (sharp dissection) | Mechanical cutting — adhesions are physically divided with cold scissors | Preferred method. No heat applied to surrounding tissue, so the risk of further endometrial damage is minimised. Particularly important for thin linings. |
| Bipolar electrosurgery | Electrical energy cuts and simultaneously coagulates | Fast and effective for denser adhesions; some heat spread to adjacent endometrium. Skill of the surgeon matters enormously. |
| Laser (Nd:YAG or KTP) | Focused light energy vaporises adhesion tissue | Precise but expensive and less widely available. Used in specialist centres. |
What to expect on the day
- Usually performed as day surgery — you go home the same day
- General anaesthetic is most common, though local or regional anaesthesia is used in some centres
- The procedure typically takes 30–60 minutes depending on the extent of adhesions
- Mild to moderate cramping is normal for 24–48 hours afterwards; most women take over-the-counter pain relief
- Light spotting for a few days to a week is common
- You will usually be back to desk work within a day or two; more physical work may take longer
How many procedures will you need?
This is one of the most important things to understand going in: most women with moderate to severe Asherman's will require more than one procedure. Adhesions reform as the raw surfaces heal — this is not a failure of the surgery; it's the biology of uterine wound healing.
- Minimal adhesions: ~3% recurrence after a single procedure
- Moderate adhesions: ~21.6% recurrence — most women need 2 procedures
- Severe adhesions: ~50% recurrence — multiple procedures are the rule, not the exception
- Most women with mild-moderate Asherman's achieve adequate cavity restoration within 1–3 procedures
A surgeon who tells you one procedure will definitively fix severe Asherman's may be underselling the complexity. A surgeon who presents a clear, step-by-step plan — first procedure, second-look hysteroscopy, further treatment if needed — is thinking about your case realistically.
Post-surgical adhesion prevention
What happens in the days and weeks after surgery may be as important as the surgery itself. The raw surfaces left where adhesions were removed will attempt to heal — and in doing so, will try to fuse back together. Post-surgical barriers are the physical interventions designed to keep the walls apart while that healing happens.
Physical barriers
| Method | How it works | Duration in place | Notes |
|---|---|---|---|
| Foley catheter balloon | A Foley catheter is inserted and the balloon inflated inside the uterine cavity, physically holding the walls apart | 3–7 days | Most widely used; inexpensive and accessible. Requires antibiotics while in place to prevent infection. Mildly uncomfortable to wear. |
| Uterine balloon stent | Purpose-built inflatable stent designed specifically for the uterine cavity; more anatomically shaped than a Foley | 5–7 days | Better anatomical fit than a Foley; used in specialist Asherman's centres. Some evidence of better adhesion prevention rates. |
| Cook balloon | Similar balloon stent principle; specific commercial device | 5–7 days | Similar profile to uterine balloon stent; choice often depends on surgeon preference and centre availability. |
| Intrauterine device (IUD) | Copper or hormonal IUD used as a mechanical spacer inside the cavity | Weeks to months | Some controversy in the literature. The Mirena IUD adds local progestogen which may aid lining; copper IUD acts as a spacer only. Evidence weaker than balloon methods for preventing re-adhesion. |
| Anti-adhesion barriers | Oxidised regenerated cellulose (Interceed) or hyaluronic acid gels (e.g. Seprafilm, Hyalobarrier) placed directly on the raw surfaces at the time of surgery | Absorbed over days | Applied at surgery, not inserted afterwards. Hyaluronic acid gel (Hyalobarrier) has the strongest evidence base for reducing re-adhesion. Used alongside, not instead of, mechanical barriers. |
Antibiotics
A course of antibiotics is routinely prescribed while any physical barrier is in place. The barrier disrupts the normal environment of the uterus and increases infection risk; antibiotics are protective — not optional.
Hormonal therapy after surgery
Oestrogen is the primary driver of endometrial growth. After surgery has removed adhesions and created fresh surfaces, oestrogen therapy is used to stimulate rapid and substantial regrowth of the uterine lining before those surfaces can scar over again. This is not optional — it is a core part of the treatment protocol.
Why standard doses aren't enough
A normal physiological oestrogen level may be insufficient to drive regrowth in a damaged endometrium. The cells have reduced receptivity, the blood supply may be impaired, and competing scar tissue is present. Supraphysiological doses — higher than the body would naturally produce — provide a strong, sustained stimulus to what remains of the functional endometrium. The analogy is volume: if the signal isn't loud enough, it won't be heard.
Post-surgical hormone protocols
| Approach | Oestrogen type | Typical dose | Duration | Progesterone |
|---|---|---|---|---|
| Standard protocol | Oestradiol valerate (oral) | 4 mg/day | 4–6 weeks | Added in final 10–14 days to trigger withdrawal bleed |
| High-dose protocol | Oestradiol valerate or oestradiol (oral or transdermal) | 6–8 mg/day | 6 weeks | Added in final 14 days; micronised progesterone preferred |
| Combined oral contraceptive pill | Various synthetic oestrogens | Standard OCP dose | One or more cycles | Combined within pill formulation |
Progesterone — what to expect
Micronised progesterone (e.g. Utrogestan) is generally preferred over synthetic progestins for post-surgical protocols, particularly in women trying to conceive. Synthetic progestins can be sufficient but may have more side effects. Your specialist will prescribe based on your clinical picture and local availability.
The follow-up hysteroscopy (second-look)
A follow-up hysteroscopy — sometimes called a second-look procedure — should be part of your treatment plan from the beginning, not an afterthought. It is performed 4–8 weeks after the initial surgery.
Why it matters
- Assesses how well the cavity has healed and how much the lining has regenerated
- Identifies any new adhesions that have formed — while they are still thin and filmy and far easier to treat than dense, established adhesions
- Provides an objective benchmark: the same surgeon, the same technique, comparing two images over time
- Allows any further treatment to happen before significant re-scarring occurs
Early re-adhesion, caught at a second-look procedure, can often be divided with minimal force using a simple instrument, sometimes even without anaesthesia. Left until symptoms return months later, those same adhesions may have matured into dense, fibrotic bands that require a full surgical procedure.
Monitoring your lining — ultrasound
Between procedures, a transvaginal ultrasound in the follicular phase (around days 10–12 of your cycle, or in the equivalent week if your cycle is irregular) is the primary non-invasive way to track how your endometrium is responding to treatment.
What you're looking for
| Measurement | What it means | Target range |
|---|---|---|
| Endometrial thickness | The depth of the entire endometrial stripe, measured in millimetres at its thickest point | ≥8mm is generally considered adequate for receptivity; ≥6mm is the lower acceptable threshold for transfer in IVF |
| Pattern: triple-line | The classic "three-line" appearance on ultrasound — a central echogenic line flanked by two hypoechoic layers — indicating healthy, layered endometrium responding to oestrogen | This pattern is a positive sign; its presence alongside adequate thickness is reassuring |
| Subendometrial blood flow | Blood flow signals within or around the endometrium on Doppler ultrasound — a proxy for uterine perfusion | Presence of subendometrial flow is positive; absent or minimal flow may indicate ongoing perfusion issues |
An endometrial thickness below 6mm — particularly if it was previously thicker — warrants a conversation with your specialist about adjusting the hormonal protocol or considering further investigation. A lining consistently below 7mm despite oestrogen therapy is sometimes called a "thin endometrium" and may require additional interventions (covered in Chapter 5).
Track your measurements at each scan. Watching the numbers improve — even incrementally — is one of the most tangible markers of recovery, and it gives you something concrete to discuss with your care team.
What does success look like?
It's worth being honest here. Outcomes in Asherman's vary significantly by severity, and complete restoration is not guaranteed for everyone. What is consistent in the literature is that the majority of women see meaningful improvement.
Menstrual outcomes
- Mild Asherman's: the large majority of women restore normal menstruation after one or two procedures
- Moderate cases: most women see improvement, though it may take 2–3 treatment cycles
- Severe cases: restoration is possible but less reliable; some women have permanent reduction in flow even after successful surgery
Pregnancy outcomes after treatment
| Severity | Pregnancy rate post-treatment | Source |
|---|---|---|
| Mild | ~60.7% | Cleveland Clinic data; composite of multiple studies |
| Moderate | ~53.4% | Cleveland Clinic data; composite of multiple studies |
| Severe | ~25% | Cleveland Clinic data; composite of multiple studies |
These numbers are meaningful but imperfect. They represent outcomes across varied populations, with varying surgical quality and post-operative protocols. Individual results depend heavily on the skill of the surgeon, the completeness of the post-surgical protocol, the baseline extent of adhesions, and other fertility factors.
Success also needs to be defined on your terms. For some women, the goal is a normal period and reduced pain — and that is achieved in the majority of mild-moderate cases. For women whose goal is pregnancy, the road may be longer and the outcome less certain — particularly in severe cases. Knowing this going in does not make the journey less worth taking; it makes it more navigable.
"Success looked different than I expected. It wasn't one dramatic moment. It was a slow accumulation of small improvements — a slightly heavier bleed, a better scan, a specialist who looked genuinely pleased with the picture."
How to find the right surgeon
This is one of the most important decisions you will make in your Asherman's journey — and one that nobody really prepares you for. You are not just finding a gynaecologist. You are finding someone with a specific sub-specialisation, a specific philosophy about post-operative care, and ideally, a volume of experience that most general OB/GYNs simply won't have.
Asherman's is rare. Many gynaecologists will see only a handful of cases in their entire career. The skills required for optimal hysteroscopic adhesiolysis — particularly for moderate to severe disease — are genuinely advanced. Where you are treated, and by whom, materially affects your outcome. That's not said to frighten you. It's said so you feel empowered to be selective.
"I didn't know I was allowed to choose. I thought you just went to whoever your gynaecologist referred you to. It took me a long time to realise that finding a surgeon who genuinely specialised in intrauterine adhesions was both possible and worth the effort."
— Daniella
What to look for in a surgeon
Green flags — signals you are in the right place
- High volume of hysteroscopic procedures. Ask directly: how many hysteroscopies do you perform per year, and how many of those are for Asherman's specifically? A surgeon who sees this regularly will have a comfort with complexity that someone who treats it occasionally simply won't.
- A clear post-operative protocol they can describe without hesitation. Removing adhesions is only half the job. How they manage the cavity afterward — hormone therapy, adhesion barriers, second-look timing — is just as important. If they're vague, that's informative.
- Experience across all grades of severity. Mild Asherman's is far more straightforward than severe. If your case is moderate or severe, you want someone who has treated severe cases many times — not someone whose experience is concentrated at the mild end.
- Willingness to discuss realistic expectations. A surgeon who tells you what you want to hear is not always telling you the truth. Someone who gives you an honest, staged picture — including the likelihood of needing more than one procedure — is treating you as an adult and being realistic about the condition.
- Affiliations with fertility or reproductive surgery programs. Surgeons who work closely with IVF units or reproductive endocrinologists tend to have sharper skills in uterine cavity restoration, because restoring the cavity for implantation is something they think about constantly.
- No dismissiveness. "It's fine, we just cut the bands" is not an adequate summary of treatment planning for anything beyond the most trivial adhesions. You want someone who takes the complexity seriously.
Red flags — signals to pause and consider a second opinion
- They cannot tell you how many Asherman's cases they have treated
- They describe no specific post-operative adhesion prevention plan
- They tell you one procedure will definitely fix it (for moderate or severe cases)
- They do not plan a second-look hysteroscopy to assess the result
- They have not recommended post-surgical oestrogen therapy
- They seem unfamiliar with adhesion prevention barriers or dismiss them without explanation
- You feel rushed, dismissed, or like your questions are inconvenient
Where to look
Finding a specialist is harder than it should be, but these are the most reliable starting points:
| Resource | What it offers |
|---|---|
| International Asherman's Association (IAA) | Maintains a directory of recommended specialists worldwide — this is the single best starting point. ashermans.org |
| Online Asherman's communities | Facebook groups (Asherman's Syndrome Support, Asherman's Syndrome Sisters) are active communities where real patients share which surgeons they have been treated by, their outcomes, and honest assessments. Invaluable, with the caveat that individual experiences vary. |
| Reproductive surgery or fertility clinics | Clinics with a dedicated reproductive surgery program — separate from their IVF unit — are more likely to have hysteroscopy specialists on staff. Worth asking any IVF clinic you are considering who they refer intrauterine adhesion cases to. |
| Academic or teaching hospitals | Major university-affiliated hospitals often have gynaecological endoscopy programs with higher surgical volume and more complex case exposure than private practice settings. |
| Your country's MIGS (minimally invasive gynaecologic surgery) society | Most countries have a professional body for minimally invasive gynaecological surgery — members tend to have stronger hysteroscopy credentials than the general OB/GYN population. |
Getting a second opinion — and why you should
A second opinion is not a sign of distrust or rudeness. It is a medically reasonable step for any significant diagnosis, and for Asherman's — where treatment complexity, surgical skill, and post-operative protocol all materially affect outcome — it is more than reasonable. It is often essential.
If you have been diagnosed with moderate or severe Asherman's, or if your first surgeon's plan doesn't include a full post-operative protocol, seek a second opinion from a centre that sees intrauterine adhesions regularly. The difference in approach can be striking. You are entitled to this.
Preparing for your first consultation
When you find someone you want to see, bring everything. All your scans. All your reports. The original hysteroscopy report if you have it (the one that first identified or caused the adhesions). Your menstrual history before and after the event that caused your Asherman's. A written timeline if it helps — it almost always does.
Bring someone with you if you can. It is extremely difficult to absorb complex clinical information and formulate good questions simultaneously when it is your own body being discussed. A second set of ears matters.
And bring the questions from the next section. Ask all of them. A surgeon who is good at this will welcome the questions — they are a sign of an engaged patient who is going to take the post-operative protocol seriously.
Questions to ask your surgeon
Walking into a consultation with these questions prepared changes the dynamic. You are not a passive recipient of a procedure. You are choosing a treatment team and a protocol that will significantly affect your outcome.
- How many Asherman's cases have you treated in the past year? Do you have a dedicated interest in intrauterine adhesions?
- What surgical technique do you use? Do you prefer sharp dissection (scissors), energy-based methods, or both — and why?
- What adhesion prevention method will you use after surgery, and for how long? Will you use any anti-adhesion barriers at the time of surgery?
- What is your hormone protocol post-surgery — what dose of oestrogen, for how long, and what progesterone will you add?
- Will we do a second-look hysteroscopy? At what interval after surgery?
- Based on my grade of Asherman's, how many procedures do you anticipate I may need?
- What does success look like for someone with my severity — what outcomes should I realistically expect?
- What are the recurrence rates in your patients with my grade of adhesions?
