Hysteroscopy for Fertility: A Complete Guide

Hysteroscopy is a procedure in which a thin, lighted telescope (the hysteroscope) is passed through the vagina and cervix into the uterine cavity, allowing direct visualization of the endometrium (uterine lining), the tubal ostia (openings of the fallopian tubes), and any abnormalities within the cavity. The uterus is gently distended with saline or carbon dioxide to create space for viewing.

The procedure can be purely diagnostic (looking only) or operative (treating what is found). This dual capability is what makes hysteroscopy uniquely valuable in fertility medicine -- your doctor can diagnose and fix problems in one session.

Diagnostic Hysteroscopy

Diagnostic hysteroscopy involves visual inspection of the uterine cavity without any surgical intervention. It is used to evaluate the cavity when imaging tests (ultrasound, saline sonohysterogram, HSG) suggest an abnormality or when unexplained infertility or recurrent pregnancy loss warrants a closer look.

Key characteristics:

• Uses a thin hysteroscope (2.5-4mm diameter)
• Can often be performed in the outpatient clinic without anaesthesia (office hysteroscopy)
• Takes 5-15 minutes
• Provides the highest resolution view of the uterine cavity available in clinical practice
• Allows directed biopsies of suspicious areas

Operative Hysteroscopy

Operative hysteroscopy combines visualization with surgical treatment. A slightly larger hysteroscope (5-9mm) is used, equipped with working channels for instruments such as scissors, grasping forceps, electrocautery loops, or mechanical morcellators.

Key characteristics:

• Typically performed in an operating theatre under general anaesthesia or regional anaesthesia
• Takes 15-60 minutes depending on the complexity of the procedure
• Can treat polyps, submucosal fibroids, uterine septum, and intrauterine adhesions
• No abdominal incisions -- the entire procedure is performed through the cervix
• Preserves uterine wall integrity (no myometrial incision in most cases)

Office Hysteroscopy vs Operating Theatre Hysteroscopy

In Indian practice, the distinction between office and theatre hysteroscopy is important for both logistics and cost:

Office hysteroscopy (outpatient, no anaesthesia or local anaesthesia):

• Uses miniature hysteroscopes (2.5-3.5mm)
• Performed in the clinic itself
• No fasting or formal anaesthesia required
• Patient can drive home afterward
• Lower cost (typically INR 3,000-8,000)
• Limited to diagnostic procedures and very minor interventions (small polyps, directed biopsy)
• Increasingly available at major fertility centres in Indian metros

Theatre hysteroscopy (daycare or inpatient, under anaesthesia):

• Uses standard operative hysteroscopes (5-9mm)
• Performed in an operating theatre or procedure room
• Requires sedation or general anaesthesia
• Patient usually goes home the same day (daycare procedure)
• Higher cost (INR 15,000-60,000+ depending on the procedure)
• Can treat all types of intrauterine pathology

Hysteroscopy is not a routine screening test for all fertility patients. It is recommended when there is a specific clinical indication suggesting an intrauterine abnormality that may be affecting conception or implantation. The main indications include:

Endometrial Polyps

Endometrial polyps are one of the most common findings on fertility workup imaging. They are localized overgrowths of endometrial tissue that project into the uterine cavity. Polyps are found in approximately 25-32% of women undergoing fertility evaluation -- significantly higher than in the general population.

Polyps are believed to affect fertility by disrupting the endometrial surface, altering local molecular signalling, creating a physical barrier to implantation, and triggering local inflammatory responses. Hysteroscopic polypectomy (removal of polyps) is the gold standard treatment, with strong evidence supporting improved fertility outcomes after removal.

Submucosal Fibroids

Submucosal fibroids (FIGO Types 0-2) grow into or distort the uterine cavity and have the strongest negative impact on fertility among all fibroid types. Hysteroscopic myomectomy -- removal of submucosal fibroids through the hysteroscope -- is the treatment of choice, avoiding abdominal incisions and preserving the uterine wall.

Hysteroscopy is both the best diagnostic tool (direct visualization) and the best treatment method (transcervical resection) for submucosal fibroids.

Uterine Septum

A uterine septum is the most common congenital uterine anomaly, found in approximately 2-3% of the general population but in 3-5% of women with infertility and up to 15% of women with recurrent pregnancy loss. The septum is a band of fibrous or fibromuscular tissue that partially or completely divides the uterine cavity.

The septum has poor blood supply compared to normal myometrium, which may impair implantation and early placental development. Hysteroscopic septum resection (metroplasty) is a straightforward procedure that removes the septum under direct vision, restoring a normal cavity shape. Unlike older abdominal approaches (Strassman procedure), hysteroscopic metroplasty requires no uterine incision and has a short recovery time.

Intrauterine Adhesions (Asherman's Syndrome)

Asherman's syndrome is a condition in which scar tissue (adhesions) forms within the uterine cavity, partially or completely obliterating the cavity space. It most commonly occurs after uterine surgery -- particularly after dilatation and curettage (D&C) for miscarriage or retained products of conception, postpartum haemorrhage management, or repeated uterine procedures.

Symptoms include reduced menstrual flow (hypomenorrhea), absent periods (amenorrhea), recurrent miscarriage, and infertility. Hysteroscopic adhesiolysis -- the careful division of adhesions under direct vision -- is the only effective treatment. The procedure restores cavity volume and endometrial surface area, allowing implantation to occur.

Recurrent IVF Implantation Failure

When a patient has undergone multiple IVF cycles with good quality embryos but fails to achieve implantation, hysteroscopy is frequently recommended as part of the workup. The rationale is that subtle intrauterine pathology -- small polyps, mild adhesions, chronic endometritis, or minor cavity distortion -- may not be visible on standard imaging but can be identified and treated hysteroscopically.

Abnormal Findings on Imaging

Hysteroscopy is indicated to evaluate and treat abnormalities first identified on:

• Transvaginal ultrasound: Suspected polyps, irregular endometrial thickening, suspected submucosal fibroids
• Saline sonohysterogram (SIS/SHG): Filling defects, cavity irregularities, suspected adhesions
• Hysterosalpingography (HSG): Intracavitary filling defects, irregular cavity contour
• MRI: Suspected uterine septum requiring confirmation and treatment

Recurrent Pregnancy Loss

Women with two or more pregnancy losses are often evaluated with hysteroscopy to rule out structural causes. ESHRE recurrent pregnancy loss guidelines recommend assessment of the uterine cavity in the workup of recurrent miscarriage, and hysteroscopy is the most accurate method for detecting and treating intracavitary abnormalities.

Understanding what happens during hysteroscopy can help reduce anxiety about the procedure. Here is the typical sequence:

Step 1: Pre-Procedure Assessment

Before hysteroscopy, your doctor will:

• Review your medical history and imaging results
• Perform a pregnancy test (hysteroscopy must not be performed during pregnancy)
• Check for active pelvic infection (a contraindication)
• Discuss whether the procedure will be diagnostic only or potentially operative
• Determine the appropriate setting (office vs theatre) and anaesthesia plan
• Schedule the procedure -- typically in the early follicular phase (Days 6-11 of the menstrual cycle) when the endometrium is thin and visualization is optimal

Step 2: Anaesthesia and Positioning

• Office hysteroscopy: No anaesthesia or a paracervical block (local anaesthetic injected around the cervix). You remain awake throughout.
• Operative hysteroscopy: General anaesthesia (you are asleep) or spinal/regional anaesthesia. Intravenous sedation is sometimes used for simpler operative procedures.
• You are positioned in the lithotomy position (legs supported in stirrups), similar to a routine gynaecological examination.

Step 3: Cervical Preparation and Hysteroscope Insertion

The cervix is gently cleaned with an antiseptic solution. For office hysteroscopy with miniature scopes, the hysteroscope can often be passed directly through the cervix without dilatation. For operative hysteroscopy, the cervix may need gentle dilatation using graduated dilators to accommodate the larger instrument.

In some cases, a cervical ripening agent (misoprostol) is given the night before or a few hours before the procedure to soften the cervix and facilitate passage of the hysteroscope.

Step 4: Uterine Distension and Inspection

Once the hysteroscope is inside the uterine cavity, distension medium is introduced to expand the cavity and allow clear visualization:

• Normal saline: Most commonly used for diagnostic and bipolar operative hysteroscopy. Safe, inexpensive, and physiological.
• Glycine or sorbitol solutions: Used with monopolar electrosurgical instruments (less common in modern practice).
• Carbon dioxide: Occasionally used for diagnostic hysteroscopy, providing excellent visualization but not suitable for operative procedures.

The surgeon systematically inspects the entire cavity: anterior wall, posterior wall, lateral walls, fundus (top), both tubal ostia, and the endocervical canal. Any abnormalities are documented -- often with photographs or video recording.

Step 5: Operative Treatment (If Indicated)

If pathology is found and operative treatment is planned:

• Polypectomy: Polyps are grasped, cut at the base, and removed using scissors, a loop electrode, or a mechanical morcellator (e.g., MyoSure, TruClear systems). The base may be cauterized to reduce recurrence.
• Myomectomy: Submucosal fibroids are resected using an electrosurgical loop (resectoscope) or mechanical morcellator. The fibroid is shaved in layers until the cavity contour is restored.
• Septum resection: The septum is incised along its midline using scissors, needle electrode, or resectoscope until the cavity assumes a normal convex fundal shape. Laparoscopic or ultrasound guidance may be used simultaneously to prevent perforation.
• Adhesiolysis: Adhesions are divided sharply using hysteroscopic scissors (preferred over electrocautery to minimize thermal damage and re-adhesion). Severe adhesions may require multiple staged procedures.

Step 6: Post-Procedure Recovery

• Office hysteroscopy: You can leave the clinic within 15-30 minutes. Mild cramping is common and usually resolves with over-the-counter pain relievers.
• Operative hysteroscopy: You are monitored in a recovery area for 1-4 hours until the effects of anaesthesia have worn off. Most patients are discharged the same day (daycare procedure).
• Light vaginal spotting or bleeding for a few days is normal.
• Antibiotics are prescribed in some cases (e.g., after adhesiolysis or in the presence of infection risk).
• Depending on the procedure, a balloon catheter or intrauterine device (IUD) may be placed temporarily after adhesiolysis to prevent re-adhesion formation.

This is one of the most debated questions in reproductive medicine, and the evidence has evolved significantly over the past decade. The core question: should all women undergoing IVF have a hysteroscopy before their first or subsequent cycle, even if imaging appears normal?

The Evidence in Favour

Several important studies have suggested a benefit:

The TROPHY Trial (2016): This randomized controlled trial published in the New England Journal of Medicine by El-Toukhy et al. found that outpatient hysteroscopy before a first IVF cycle in women with a normal ultrasound did not significantly improve live birth rates overall. However, a subgroup analysis suggested potential benefit in women where small pathologies were discovered and treated.

Cochrane Review (2019): A Cochrane systematic review by Kasius et al. examined the evidence for routine hysteroscopy before the first IVF cycle. The review concluded that hysteroscopy may improve clinical pregnancy rates (moderate-quality evidence) but called for more high-quality trials before recommending routine use.

Studies in Recurrent Implantation Failure (RIF): The evidence is stronger for hysteroscopy before repeat IVF cycles after implantation failure. A meta-analysis by Potdar et al. (2012) found that hysteroscopy in women with recurrent implantation failure revealed unsuspected intrauterine pathology in 25-50% of cases, and treatment was associated with improved pregnancy rates in subsequent cycles.

ESHRE RIF Guideline (2023): The ESHRE guideline on recurrent implantation failure recommends hysteroscopy as part of the RIF workup, noting that previously undetected uterine pathology is found in a significant proportion of RIF patients.

The Evidence Against Routine Use

The inSIGHT Trial (2016): A large Dutch randomized trial published in The Lancet by Smit et al. found that routine hysteroscopy before a first IVF cycle in women with a normal transvaginal ultrasound did not improve ongoing pregnancy rates or live birth rates. This was one of the largest and most rigorous trials on this question.

ASRM Committee Opinion: ASRM does not recommend routine hysteroscopy for all patients before a first IVF cycle. Their position is that hysteroscopy should be performed when there is a specific indication -- abnormal imaging, history of intrauterine surgery, recurrent implantation failure, or recurrent pregnancy loss.

What the Evidence Actually Means

The most balanced interpretation of the current evidence is:

1. Routine hysteroscopy before a first IVF cycle with normal imaging is not supported by the strongest evidence. The inSIGHT trial and ASRM guidelines do not recommend it as standard practice.

1. Hysteroscopy is clearly indicated before IVF when imaging is abnormal -- suspected polyps, fibroids, septum, adhesions, or irregular cavity contour. There is no debate about this.

1. Hysteroscopy before repeat IVF after implantation failure is supported -- unsuspected pathology is found in 25-50% of RIF cases, and treatment improves outcomes.

1. Office hysteroscopy can detect subtle pathology missed by imaging -- small polyps (less than 1 cm), mild adhesions, chronic endometritis (when combined with biopsy), and minor cavity irregularities. Studies show that up to 40% of women with a "normal" ultrasound may have findings on hysteroscopy.

1. When pathology is found and treated, IVF outcomes improve -- this is well established for polyps, submucosal fibroids, and adhesions.

The fertility impact of hysteroscopy depends entirely on what is found and treated. Here are the evidence-based outcomes for the most common hysteroscopic procedures:

After Hysteroscopic Polypectomy

Endometrial polyps are the most common finding and polypectomy the most common hysteroscopic procedure in fertility patients.

• A randomized controlled trial by Perez-Medina et al. (2005) demonstrated that hysteroscopic polypectomy before IUI doubled the pregnancy rate compared to diagnostic hysteroscopy alone (63% vs 28%)
• IVF pregnancy rates improve after polypectomy, with studies reporting clinical pregnancy rates of 40-65% per transfer after removal of polyps larger than 1 cm
• Polyps smaller than 1 cm are more controversial -- some studies suggest they do not significantly affect IVF outcomes, while others recommend removal of all polyps in the fertility context
• Recurrence rates for polyps are approximately 15-30% over 2-3 years

After Hysteroscopic Myomectomy

Submucosal fibroid removal has well-established fertility benefits:

• Pregnancy rates after hysteroscopic myomectomy range from 40-70% depending on fibroid type, size, and whether the fibroid was the sole fertility factor
• FIGO Type 0 fibroids (entirely intracavitary) show the best post-surgical fertility outcomes, with pregnancy rates up to 57%
• FIGO Type 1 fibroids (more than 50% intracavitary) show pregnancy rates of approximately 43%
• FIGO Type 2 fibroids (less than 50% intracavitary) have lower pregnancy rates (approximately 25%) and may require staged procedures
• IVF live birth rates improve significantly after removal of submucosal fibroids that were distorting the cavity

After Hysteroscopic Septum Resection

The evidence for septum resection and fertility outcomes has been the subject of significant recent debate:

• The TRUST trial (2021), a randomized controlled trial published in the New England Journal of Medicine, found that hysteroscopic septum resection did not improve live birth rates compared to expectant management in women with a septate uterus and a history of subfertility, miscarriage, or preterm birth
• This challenged decades of observational data suggesting major benefits from septoplasty
• Despite the TRUST trial, many reproductive surgeons continue to recommend septum resection for patients with recurrent pregnancy loss and a significant septum, noting limitations in the trial design
• ASRM and ESHRE guidelines now recommend shared decision-making rather than routine septum resection, acknowledging the uncertain evidence
• When performed, septum resection is associated with pregnancy rates of 50-70% in observational studies, though these outcomes may partly reflect selection bias

After Hysteroscopic Adhesiolysis (Asherman's Syndrome)

Outcomes after adhesiolysis depend heavily on the severity of adhesions:

• Mild adhesions: Pregnancy rates of 70-80% after treatment, with miscarriage rates similar to the general population
• Moderate adhesions: Pregnancy rates of 50-60%, with some ongoing risk of re-adhesion and recurrent loss
• Severe adhesions (complete cavity obliteration): Pregnancy rates of 20-40%, often requiring multiple staged procedures. Re-adhesion rates are high (25-50%) and ongoing endometrial thinning may limit outcomes
• IVF success after adhesiolysis depends on the degree of endometrial recovery -- a post-treatment endometrial thickness of 7mm or greater is associated with better outcomes

Hysteroscopy costs in India vary significantly based on the type of procedure, the city, the facility, and whether additional procedures are performed.

Diagnostic Hysteroscopy

Operative Hysteroscopy

What Affects the Cost?

• Anaesthesia type: Office hysteroscopy without anaesthesia is cheapest. General anaesthesia adds INR 5,000-15,000.
• Facility type: Fertility centre daycare procedure rooms are typically less expensive than full hospital operating theatres.
• Procedure complexity: Simple polypectomy is faster and cheaper than complex myomectomy or severe adhesiolysis.
• Equipment used: Mechanical morcellation systems (MyoSure, TruClear) are newer and may cost more than traditional resectoscope techniques.
• Hospital stay: Most hysteroscopic procedures are daycare. If an overnight stay is needed (uncommon), hospital charges increase.
• Combined procedures: Hysteroscopy combined with laparoscopy (hysteroscopy + laparoscopy for a complete fertility assessment) costs INR 40,000-1,00,000 depending on the city and hospital.

Additional Costs to Consider

• Pre-operative tests: Blood work, ECG, anaesthesia assessment -- INR 2,000-5,000
• Histopathology: Tissue sent for examination after polypectomy or biopsy -- INR 1,000-3,000
• Post-operative medications: Antibiotics, hormones (estrogen therapy after adhesiolysis) -- INR 500-2,000
• Follow-up hysteroscopy: Required in some cases, especially after adhesiolysis -- adds the cost of a second procedure

Hysteroscopy is a safe procedure with a low overall complication rate, but like all surgical procedures, it carries some risks. Understanding these helps you have an informed discussion with your doctor.

Common Minor Side Effects (Not True Complications)

• Cramping: Mild to moderate uterine cramping during and after the procedure, especially with office hysteroscopy. Usually resolves within 24 hours.
• Light bleeding: Spotting or light vaginal bleeding for 2-7 days after the procedure. This is normal.
• Vasovagal reaction: Lightheadedness or brief fainting during office hysteroscopy (occurs in approximately 1-2% of office procedures). Managed by stopping the procedure briefly and positioning the patient appropriately.

Uncommon Complications (1-5% of Operative Cases)

• Uterine perforation: The hysteroscope or surgical instrument passes through the uterine wall. This is the most significant risk of hysteroscopy, occurring in approximately 0.5-1.5% of operative procedures. Most perforations are small, cause no lasting damage, and heal without intervention. If a perforation occurs during electrosurgical resection, laparoscopy may be performed to check for internal organ injury.
• Cervical laceration: Tearing of the cervix during dilatation, occurring in fewer than 1% of procedures. Usually repaired with a suture at the time.
• Bleeding requiring intervention: While some bleeding is normal, excessive bleeding requiring additional treatment (cauterization, balloon tamponade, or rarely transfusion) occurs in approximately 1-2% of myomectomy procedures.

Rare Complications (Less Than 1%)

• Fluid overload: Excessive absorption of distension medium into the bloodstream. More common with non-electrolyte solutions (glycine, sorbitol) used with monopolar instruments. Monitored closely during the procedure by tracking fluid deficit. Modern use of normal saline with bipolar instruments has significantly reduced this risk.
• Infection: Post-procedure endometritis occurs in fewer than 1% of cases. Treated with antibiotics. Prophylactic antibiotics are given for some procedures.
• Intrauterine adhesion formation: Paradoxically, hysteroscopic surgery can sometimes lead to adhesion formation, particularly after resection of opposing wall fibroids or extensive endometrial surgery. Strategies to prevent this include barrier gels, estrogen therapy, and temporary intrauterine devices.
• Thermal injury: Damage to surrounding tissue from electrosurgical instruments. Minimized by experienced surgeons using appropriate power settings and techniques.

Anaesthesia Risks

When general anaesthesia is used, standard anaesthetic risks apply (allergic reactions, respiratory complications). These are very rare in healthy patients undergoing short procedures.

Recovery after hysteroscopy is generally quick, but the timeline varies based on the type of procedure performed.

After Diagnostic Hysteroscopy (Office)

• Day of procedure: Resume normal activities immediately. Mild cramping and spotting expected.
• Days 1-2: Any cramping typically resolves. Light spotting may continue.
• Fertility: No delay to fertility treatment. IVF or IUI can proceed in the same or next cycle.

After Simple Operative Hysteroscopy (Polypectomy, Minor Adhesiolysis)

• Day of procedure: Rest at home after discharge from daycare. Mild cramping managed with paracetamol or ibuprofen.
• Days 1-3: Return to desk work and normal daily activities. Avoid strenuous exercise.
• Days 3-7: Spotting usually resolves. Resume all normal activities.
• Fertility: Most specialists recommend waiting one menstrual cycle (approximately 4-6 weeks) before attempting conception or starting an IVF cycle, allowing the endometrium to regenerate fully.

After Complex Operative Hysteroscopy (Myomectomy, Septum Resection, Severe Adhesiolysis)

• Day of procedure: Rest at home after daycare discharge. Pain medications as prescribed.
• Days 1-5: Gradually resume normal activities. Avoid heavy lifting, vigorous exercise, and sexual intercourse.
• Week 1-2: Most women feel fully recovered. Bleeding typically stops within 7-10 days.
• Fertility after myomectomy: Wait 2-3 months before attempting conception. No waiting period for caesarean delivery concerns (unlike abdominal myomectomy) since there is no uterine wall incision.
• Fertility after septum resection: Wait 1-2 months. Some specialists allow earlier attempts.
• Fertility after severe adhesiolysis: Wait 2-3 months. A follow-up hysteroscopy at 4-8 weeks is often recommended to check for re-adhesion before attempting conception.

When to Contact Your Doctor After Hysteroscopy

Seek medical attention if you experience:

• Heavy bleeding (soaking more than one pad per hour for more than 2 hours)
• Fever above 38 degrees Celsius (100.4 degrees Fahrenheit)
• Severe abdominal pain not relieved by prescribed medications
• Foul-smelling vaginal discharge (suggesting infection)
• Inability to urinate
