What Is Saline Infusion Sonography (SIS)?

Saline Infusion Sonography (SIS), also known as saline ultrasound, sonohysterography, or saline contrast ultrasound, is a specialised pelvic ultrasound that uses a sterile saline solution to expand the uterine cavity gently.

This allows your clinician to obtain clearer images of the uterus than a standard transvaginal ultrasound.

The procedure helps assess the shape and condition of the uterine cavity and identify abnormalities that may interfere with fertility, embryo implantation, or normal menstrual health.

Unlike more invasive procedures, an SIS scan is performed in an outpatient setting, requires no general anaesthetic, and is usually completed within 20 to 30 minutes.

Who Should Book an SIS Scan in London?

As a private gynaecology Clinic in London, we provide SIS scans for women at different stages of their fertility journey, helping them understand potential uterine concerns and make informed decisions about their next steps.

1. Women Trying to Conceive Naturally

If you have been trying to conceive naturally without success, an SIS scan can help identify uterine factors that may be affecting your fertility. It provides a clearer view of the uterine cavity compared to a standard ultrasound.

By detecting issues such as polyps, fibroids, or scar tissue, SIS helps your fertility specialist recommend the most suitable approach to support your pregnancy journey.

2. Couples Preparing for IVF or IUI

Before starting fertility treatments such as IVF or IUI, many specialists recommend checking the health of the uterine cavity. A healthy uterus provides the best possible environment for embryo implantation.

An SIS scan helps identify any abnormalities that could impact treatment success, allowing your care team to address potential concerns before beginning treatment.

3. Women with Recurrent Miscarriages

Experiencing repeated miscarriages can be emotionally challenging, and identifying the possible causes is an important step. SIS helps assess the structure of the uterus to detect abnormalities that may contribute to pregnancy loss.

The scan can reveal conditions such as a uterine septum, fibroids, or scar tissue that may require further evaluation or treatment.

4. Patients Experiencing Abnormal Uterine Bleeding

Heavy, prolonged, or irregular periods may sometimes be linked to changes inside the uterus. An SIS scan provides detailed images of the uterine lining and cavity to investigate possible causes.

It can help detect conditions such as uterine polyps, fibroids, or endometrial changes that may not always be visible during a routine ultrasound.

5. Women with Failed Embryo Implantation

If previous IVF attempts have not resulted in successful embryo implantation, an SIS scan can help investigate possible uterine-related factors. A clear assessment of the uterine cavity may reveal issues affecting implantation.

Identifying and treating these concerns can help improve fertility treatment planning and provide a better understanding of your reproductive health.

6. Patients with Suspected Uterine Abnormalities

Women with previous abnormal ultrasound results or suspected uterine conditions may benefit from a more detailed evaluation with Saline Infusion Sonography. The scan provides a closer look at the shape and structure of the uterine cavity.

At The Luna Clinic, SIS helps our specialists accurately assess uterine health and recommend personalised care based on your individual needs.

When Is Saline Infusion Sonography Recommended?

As the top IVF clinic in London, SIS is commonly used as part of fertility assessments and gynaecological investigations, helping patients receive accurate answers and the right care plan at the right time.

Before IVF Treatment

A healthy uterine cavity is essential before embryo transfer. SIS helps identify issues that could affect implantation or pregnancy success.

Before IUI Treatment

Your fertility specialist may recommend an SIS scan before intrauterine insemination to assess the uterus and optimise treatment planning.

During Fertility Testing

SIS is commonly included as part of a comprehensive fertility assessment alongside hormone testing, ovarian reserve evaluation, and pelvic ultrasound.

After Recurrent Miscarriages

The procedure helps investigate structural abnormalities that may contribute to repeated pregnancy loss.

After an Abnormal Ultrasound

If a standard ultrasound identifies an unclear finding, SIS provides better visualisation for a more accurate diagnosis.

For Heavy or Irregular Periods

Women experiencing unusual menstrual bleeding often undergo SIS to investigate possible causes within the uterine cavity.

Before Planning a Pregnancy

Some women choose an SIS scan before trying to conceive, particularly if they have a history of gynaecological conditions or previous uterine surgery.

Conditions We Detect and Diagnose with SIS Scan in London

Our fertility specialists use SIS to accurately investigate possible uterine abnormalities and provide personalised recommendations based on your results.

1. Uterine Polyps

Polyps are small growths inside the uterus that may interfere with implantation or cause abnormal bleeding.

2. Uterine Fibroids

SIS helps determine whether fibroids extend into the uterine cavity and whether they may affect fertility or pregnancy.

3. Endometrial Polyps

The procedure clearly identifies polyps arising from the endometrial lining that may require treatment.

4. Endometrial Thickening

An abnormally thick uterine lining can be evaluated more accurately using saline-enhanced imaging.

5. Uterine Septum

A uterine septum is a congenital condition that may increase the risk of miscarriage or infertility. SIS helps assess its size and location.

6. Scar Tissue (Asherman's Syndrome)

Scar tissue inside the uterus can develop after surgery or infection and may affect menstrual cycles and fertility.

7. Congenital Uterine Abnormalities

SIS helps diagnose abnormalities present from birth, including unusual uterine shapes that may impact pregnancy outcomes.

8. Other Uterine Conditions Affecting Fertility

The examination can also identify adhesions, cavity irregularities, retained tissue, and other structural abnormalities requiring further treatment.

Step-by-Step SIS Scan Process at Our Clinic in London

Your appointment is designed to be straightforward and comfortable.

The procedure usually includes:

An initial consultation and review of your medical history.
A routine transvaginal ultrasound.
Gentle placement of a small catheter into the cervix.
Slow infusion of sterile saline into the uterus.
Real-time ultrasound imaging of the uterine cavity.
Removal of the catheter and discussion of preliminary findings.

The entire appointment generally takes around 30 minutes.

Preparing for Your Saline Infusion Sonography

Preparation is simple.

Your IVF specialist clinic will usually recommend scheduling the scan shortly after your menstrual period but before ovulation. This provides the clearest images and avoids disrupting an early pregnancy.

You may also be advised to:

Inform us if you could be pregnant.
Tell us about any pelvic infections or recent symptoms.
Take pain relief beforehand if recommended.
Arrive with any previous fertility or ultrasound reports.

Recovery After an SIS Scan

Most women recover quickly and return to normal daily activities immediately after the procedure.

You may experience mild cramping or light spotting for a short time, which usually settles within a day.

Our team will explain what is normal after the scan and advise when to contact us if you experience unusual symptoms.

Understanding Your SIS Results

Following your examination, your specialist will review the images and explain the findings in clear, simple language.

Depending on the results, we may recommend:

No further treatment if the uterus appears normal
Additional fertility investigations
Hysteroscopy for further assessment
Removal of polyps or fibroids
Fertility treatment such as IVF or IUI
Personalised reproductive care based on your diagnosis

Our focus is to help you understand your options and make informed decisions about your care.

What to Expect During Your SIS Appointment at The Luna Clinic

From the moment you arrive, our team aims to make your experience as comfortable and reassuring as possible.

You’ll receive personalised care from experienced fertility professionals who take time to answer your questions, explain every stage of the procedure, and discuss your results.

How Saline Infusion Sonography Supports Fertility Treatment

A successful pregnancy often begins with a healthy uterine environment.

Saline Infusion Sonography helps fertility specialists identify conditions that could reduce implantation rates or increase miscarriage risk before treatment begins.

By detecting abnormalities early, SIS allows your care team to recommend appropriate treatment before IVF or IUI, improving treatment planning and helping create the best possible conditions for pregnancy.
