Hysteroscopy for Asherman's Syndrome:
What Nobody Told Me

If you've recently been diagnosed with Asherman's syndrome and your doctor has recommended a hysteroscopy, you've probably done what most of us do: fallen down a research rabbit hole at 11pm, emerged more confused, and woken up no less anxious. This article is my attempt to be the friend I needed back then — the one who'd already been through it and would tell you the parts the medical team forgot to mention.

This isn't medical advice. It's lived experience, backed by research I wish I'd had. Your specialist is the right person to guide your treatment. But you deserve to walk into that procedure room informed, not blindsided.

What hysteroscopy actually is

A hysteroscope is essentially a very slender camera — about the width of a pen — fitted with a light source and passed through your vagina and cervix into your uterus. It allows a surgeon to see the inside of your uterine cavity in real time on a monitor. No incisions. No stitches. Just a carefully guided instrument that goes the way nature already made.

That visual access is the whole point: Asherman's syndrome is defined by intrauterine adhesions — bands of scar tissue that form after the uterine walls are damaged and then, as they heal, stick to each other. You can't feel them. A standard ultrasound often misses them. A hysteroscope is the gold-standard tool for both diagnosing how severe they are and, when equipped with the right instruments, removing them.

Diagnostic vs operative hysteroscopy — not the same thing

This distinction confused me enormously, and it matters for managing your expectations:

• Diagnostic hysteroscopy is a "look inside" procedure. The scope goes in, the surgeon maps the adhesions, grades their severity, and comes out. Nothing is treated. You may have this first if your doctor needs to stage your Asherman's before deciding on a treatment plan — or sometimes the diagnosis and treatment happen in a single combined procedure.
• Operative hysteroscopy (specifically hysteroscopic adhesiolysis) is the treatment step. Fine scissors, a resectoscope, or laser energy are passed alongside or through the hysteroscope to cut, divide, and remove the scar tissue. This is what most people mean when they say they're "having a hysteroscopy for Asherman's."

Some surgeons stage these as separate visits; others do both in one anaesthetic. Ask your surgeon explicitly which you're having and why, so you aren't expecting to wake up "fixed" after what was always only a diagnostic procedure.

What adhesiolysis involves

The word "adhesiolysis" sounds formidable. It simply means the lysis — the breaking down — of adhesions. During operative hysteroscopy for Asherman's syndrome, your surgeon uses specialised micro-instruments passed alongside the camera to systematically divide the scar bands. Think of it like carefully cutting the threads that are holding your uterine walls together where they shouldn't be touching.

The goal is to restore the uterine cavity to as close to its natural, open shape as possible. Filmy, thin adhesions (mild Asherman's) come apart relatively easily. Dense, fibrous adhesions — the kind found in severe Asherman's where more than two-thirds of the cavity is affected — require more time, more skill, and often more than one procedure. According to the Cleveland Clinic, most patients regain their periods after up to three hysteroscopic procedures.

One thing that helped me understand the stakes: adhesions are graded mild, moderate, or severe based on how much of the cavity is affected and what kind of scar tissue it is. Your outcome is strongly tied to your starting point. Research published in the Journal of Human Reproductive Sciences found pregnancy rates of 53.8% in mild cases versus 9.5% in severe cases — a wide range that underscores why no two journeys with Asherman's are the same.

Before the procedure: what to expect at pre-op

Your pre-operative appointment exists for your safety and for the surgeon's preparation. Here's what mine covered — and what I'd encourage you to bring up if it isn't mentioned:

Write your questions down. Genuinely. You will forget them the moment you walk into the room. I asked my specialist about success rates, how long she expected the procedure to take, what she'd do if the adhesions were more severe than expected, and what the post-operative protocol looked like. Every answer mattered to how I prepared emotionally.

The day itself: what it's really like

Operative hysteroscopy for Asherman's syndrome typically takes between 30 minutes and 90 minutes depending on adhesion severity, though you should budget a full day for hospital admission, anaesthesia preparation, the procedure, and recovery room time.

For most Asherman's patients, the procedure is performed under general anaesthesia. You will be unconscious. You will feel nothing during it. This was actually one of the things I found reassuring once I understood it — the fear of pain during the procedure is almost always unfounded for operative adhesiolysis.

What you will feel before you go under is the IV going in, the cold of the operating suite, and a strange bureaucratic calm — a lot of forms, a lot of asking your name and date of birth, and then very quickly, nothing. Then you wake up in recovery feeling groggy, possibly nauseous, with cramping that ranges from mild period pain to something considerably stronger depending on what was done.

The fluid used to distend the uterine cavity during the procedure (usually saline or glycine solution) can cause bloating that lasts a day or two. This is normal. The cramping often peaks in the first few hours and then settles into something more manageable.

Immediately after: what's normal, what's not

In the hours following your procedure, expect:

• Cramping — similar to moderate period pain, occasionally stronger
• Light to moderate spotting or bleeding, sometimes with small clots
• Watery or pink discharge (this is the distension fluid clearing)
• Nausea from anaesthesia
• Fatigue and emotional fragility — this is completely normal and often underestimated

Contact your surgical team promptly if you experience: heavy bleeding (soaking more than one pad per hour), fever above 38°C, foul-smelling discharge, severe unrelenting pain, or feeling faint.

Recovery week: what to avoid, what helps

The first week is the one that matters most for both physical healing and for the fragile new uterine lining that's trying to form where scar tissue used to be. Here's the general guidance most specialists give — yours may vary:

• Avoid intercourse for at least 4–6 weeks, or as directed by your surgeon
• No tampons — pads only during any bleeding
• No swimming pools, hot tubs, or baths (showers are fine)
• Reduce strenuous exercise for the first week; gentle walking is encouraged
• Rest genuinely — if you can take a few days off work, take them
• Anti-inflammatories like ibuprofen typically help with cramping (confirm with your doctor given your full medication picture)
• Heat packs on the lower abdomen are deeply comforting and perfectly safe

Follow-up: the estrogen protocol and barrier methods

This is the part that often gets the least explanation but is arguably the most important part of Asherman's treatment. Removing adhesions is step one. Keeping them from coming back is the ongoing work.

Most specialists prescribe a course of oestrogen (estrogen) after hysteroscopic adhesiolysis — typically oral or patch-form oestrogen for 4–8 weeks, sometimes with progesterone added in the second half to induce a withdrawal bleed. The hormone support serves two purposes: it encourages the endometrium to regrow over the raw surfaces left after adhesion removal, and it helps suppress the inflammatory response that drives new scar formation.

Some surgeons also place a uterine balloon or intrauterine catheter inside the uterus at the time of surgery — a physical barrier to keep the walls apart while the lining heals. It's typically removed within a week at a follow-up appointment. This step can feel undignified and uncomfortable, but it meaningfully reduces re-adhesion rates.

As the Cleveland Clinic notes, your provider may also schedule a follow-up hysteroscopy 4–8 weeks later to check for early new adhesions while they're still thin and easy to divide — a "second-look" procedure that many specialists consider standard of care for moderate and severe cases.

Recurrence: the honest truth

Adhesions can come back. This is the hardest thing to say, but you need to know it going in. Research published in the Journal of Human Reproductive Sciences found that 63.3% of patients required a second-look hysteroscopy after their first procedure, and 6 of those 38 went on to need a third. That's not failure — that's the nature of scar tissue biology.

Re-adhesion is more common in severe cases and in patients where the underlying cause hasn't been addressed (infection, for example). The likelihood of adhesions reforming is also why the post-operative hormone protocol and barrier methods are not optional add-ons — they're integral parts of treatment.

If you do need a second or third procedure, it isn't a sign that your surgery failed or that your body is working against you. It's a sign that Asherman's is a condition that requires sustained management, not a single fix.

Success rates and managing expectations

The research gives us meaningful data, and it also reminds us that outcomes are not guarantees. According to Cleveland Clinic, post-treatment pregnancy rates vary widely by adhesion severity:

• Mild Asherman's: approximately 60.7% pregnancy rate after treatment
• Moderate Asherman's: approximately 53.4%
• Severe Asherman's: approximately 25%

The study published in the Journal of Human Reproductive Sciences similarly found that patients whose endometrial echo pattern normalised after treatment had a 54.5% pregnancy rate — compared to 10.5% in those whose echo pattern remained abnormal. In other words: the quality of the restoration matters as much as the act of operating.

What helps me hold these statistics is this: they are population data. They describe averages across people with different severities, different ages, different co-existing factors. Your individual path — with the right specialist, the right post-operative protocol, and the right follow-up care — is yours, not the average.

What I wish I'd packed and done differently

Practical, unglamorous, but genuinely useful:

What I'd do differently: I'd track everything from day one. My cycle changes, my lining measurements at ultrasound, how I was feeling emotionally — it all matters when you're trying to see whether you're improving. I kept mental notes when I should have been keeping actual records. You'll make better decisions, have better conversations with your specialist, and feel far less like the information is slipping away from you.

And if you want to understand the bigger picture — what Asherman's is doing to your hormones, how to read your own scan reports, how to advocate for yourself at appointments — the Complete Guide covers everything I wished existed when I started this journey.
