Hysteroscopy: when a 15-minute procedure changes everything that follows

A hysteroscopy lets a fertility specialist see the inside of your uterus directly, with a fine-bore camera passed through the cervix. Most patients hear about it after an imaging finding – a polyp on a scan, a suspected septum, an unexplained recurrent failure. Here is what it actually does.

What a hysteroscopy is, exactly

A 3 mm to 5 mm camera (a hysteroscope) is passed through the cervix into the uterine cavity. Saline distends the cavity so the walls separate and the surgeon can see clearly. Diagnostic-only hysteroscopies take 5 to 10 minutes and can be done in clinic without anaesthesia. Operative hysteroscopies, where a polyp or septum is removed, typically need light sedation and run 20 to 40 minutes.

What it finds that imaging misses

Endometrial polyps, submucosal fibroids, intrauterine adhesions (Asherman syndrome), uterine septa, retained products of conception, and chronic endometritis. Each of these can prevent implantation or cause recurrent loss while remaining invisible or ambiguous on routine ultrasound. A 3D ultrasound or saline-infusion sono-HSG closes some of this gap, but hysteroscopy remains the gold standard.

When fertility specialists actually order it

After a finding on ultrasound or saline-infusion sono. Before IVF in patients with prior failed cycles or thin endometrial lining. After two or more pregnancy losses. Sometimes as part of a “see and treat” workup before a first IVF transfer when something looked off on imaging. Increasingly rarely as a routine pre-IVF step in normal cavities, where the evidence does not support universal screening.

What recovery looks like

Mild cramping and light spotting for one or two days. Most patients return to normal activity within 24 hours. Operative hysteroscopies for polyp or septum removal carry small risks of infection or uterine perforation, both rare in experienced hands.

Questions worth asking your doctor

• Why are you recommending hysteroscopy now, and what specifically are you looking for?
• Is this diagnostic-only, or should we plan for “see and treat” if you find something?
• How likely is it that what we find will change our treatment plan?
• What is your perforation rate and your operative complication rate?
• How long should we wait after hysteroscopy before our next transfer?
