A Patient’s Story
Leila, 33, had been trying to conceive for a year. Every month felt like a new negotiation with hope. Her blood tests were fine, her partner’s results were reassuring, but one question kept coming back: are her fallopian tubes open?
She wanted an answer that was clear, practical, and delivered with privacy. At LSDC Healthcare in Central London, her consultant explained HyCoSy, a scan that checks tubal patency using ultrasound. Leila’s biggest worry was discomfort. Her consultant set expectations honestly, talked through pain relief options, and explained what the test can and cannot prove. Leila left feeling informed, not overwhelmed.
What Is HyCoSy?
HyCoSy stands for hysterosalpingo contrast sonography. It is an ultrasound-based test used to assess:
The uterine cavity
Whether the fallopian tubes appear open (this is called tubal patency)
A small amount of sterile fluid, contrast, or foam is introduced through the cervix, and ultrasound is used to track how it moves through the uterus and tubes. The aim is to provide clinically useful information without surgery.
If you are searching for HyCoSy London private, you are usually looking for a fertility investigation that is:
Consultant-led
Efficient and targeted
Focused on clear next steps
Why HyCoSy Is Used in Fertility Care
HyCoSy is commonly considered when pregnancy has not happened despite regular attempts, or when there is a history that suggests tubal factors might play a role.
A consultant may recommend HyCoSy when there is concern about:
Previous pelvic infection
Endometriosis
Prior pelvic or abdominal surgery
Ectopic pregnancy history
Recurrent miscarriage where cavity and tubal assessment is relevant
Unexplained difficulty conceiving
HyCoSy is one part of fertility assessment. It is most useful when interpreted alongside your history, hormone tests, ovulation pattern, and semen analysis.
What HyCoSy Can and Cannot Tell You
What it can help assess
HyCoSy can provide information about:
Whether tubes appear patent or possibly blocked
Whether there is spasm or slow flow that needs cautious interpretation
The shape of the uterine cavity, which may suggest polyps, fibroids, or other cavity issues
What it cannot guarantee
HyCoSy cannot promise pregnancy, and it cannot fully explain all fertility problems. A tube may appear open yet still not function optimally. Fertility is multi-factorial, and imaging is just one piece of the puzzle.
HyCoSy vs HSG vs Laparoscopy
There are several ways to assess tubes. The best choice depends on your clinical context.
HyCoSy
Ultrasound-based
No ionising radiation
Provides real-time imaging under specialist interpretation
HSG
X-ray based tubal test
Uses contrast with imaging under fluoroscopy
May be recommended in specific settings depending on access and clinical need
Laparoscopy with dye
Surgical procedure under anaesthesia
Can directly visualise pelvis and assess endometriosis or adhesions
Usually reserved for specific indications, not as a first test
A consultant-led approach helps match the investigation to the decision that needs to be made next.
What Happens During a HyCoSy Appointment
A typical HyCoSy process includes:
Review of your history, cycles, and fertility goals
A pelvic ultrasound assessment first
Gentle placement of a speculum
A thin catheter passed through the cervix
Introduction of fluid, contrast, or foam while ultrasound tracks flow
Discussion of findings and what they mean
The procedure is usually brief, but the value comes from the interpretation and the plan afterwards.
What It Feels Like
Most women describe:
Period-like cramping
Pressure during catheter placement
Brief stronger cramping when the fluid is introduced
Discomfort varies. Factors include cervical sensitivity, anxiety, previous procedures, and underlying pelvic pain conditions.
Comfort support may include:
Taking simple pain relief beforehand if clinically suitable
A slow, communicated pace with continuous consent
Pausing if cramps escalate
You are not expected to tolerate severe pain. A well-run clinic adapts the plan.
Timing in Your Cycle
HyCoSy is usually scheduled at a specific time in the menstrual cycle to:
Improve visibility
Reduce the chance of performing the test during pregnancy
Your consultant will advise based on your cycle pattern and clinical indication.
Who Should Not Have HyCoSy
HyCoSy may be postponed or avoided if there is:
Possible or confirmed pregnancy
Suspected pelvic infection
Unexplained fever or significant pelvic tenderness
Heavy bleeding on the day that obscures imaging
Your clinician will also check relevant allergies and medical history based on the specific contrast approach used.
Results and What Happens Next
A useful HyCoSy appointment ends with clarity. Possible outcomes include:
Tubes appear open, and the next step focuses on other fertility factors
One or both tubes appear possibly blocked, and further evaluation is discussed
The uterine cavity suggests a lesion such as a polyp or submucosal fibroid, and targeted investigation is considered
Findings are uncertain due to spasm or technical limits, and a repeat or alternative test is discussed
The point is not to label you with a result. The point is to decide the next best step with minimal delay and maximum sense.
Safety and Aftercare
HyCoSy is widely used and generally safe, but it is still a medical procedure.
After the test you may have:
Mild cramping for a short period
Light spotting
A watery discharge
Seek urgent medical care if you develop:
Fever or chills
Worsening pelvic pain that does not settle
Heavy bleeding
Feeling faint or unwell
