Hysterosalpingography (HSG / Tubal X-ray): checking your fallopian tubes as part of a fertility work-up in Turkey
Two fears bring most women to an HSG: that the test itself will be unbearable, and that "blocked tubes" will close the door on having a child. Both are usually overstated. A hysterosalpingography is a short X-ray test that shows whether your fallopian tubes are open and outlines the shape of your uterus, and a result that looks like a blockage is often a temporary spasm rather than a true obstruction. At the practice of Associate Professor Dr. Cengiz Andan in Turkey, we treat the HSG not as an isolated test but as one clear step in a fertility plan, and we read every result in the full context of your history. For women travelling from abroad, we explain the process from start to finish, plainly and based on evidence.
At a glance
- What it is: Hysterosalpingography (HSG), also called a tubal X-ray, checks whether the fallopian tubes are open and outlines the uterine cavity.
- Why it matters: Tubal factors are a major cause of female infertility, so the HSG is a core part of the fertility work-up.
- Fertility bonus: The flushing during HSG, especially with oil-based contrast, can modestly raise pregnancy chances in unexplained subfertility.
- In Turkey: The test takes about 5 to 10 minutes and is done as an outpatient procedure, with a short stay of 2 to 3 days enough for travellers.
- Starting from abroad: You can begin remotely with a review of your history and reports; your results are prepared in English for your home doctor.
What exactly is an HSG, and what does it show?
A hysterosalpingography (HSG), often called a tubal X-ray or uterine dye test, is an X-ray examination that shows whether your fallopian tubes are open and what the inside of your uterus looks like. During the test a contrast medium is passed gently through the cervix, and as it fills the cavity and spills out of the tubes, an X-ray captures the path. Two questions are answered at once: is the uterine cavity normal in shape, and can fluid pass freely through each tube. This is different from a routine pelvic ultrasound, which looks at the ovaries and uterine wall but cannot reliably tell whether the tubes are open.
Why is an HSG part of the fertility work-up?
Open fallopian tubes are essential for natural conception, which is why checking them is one of the first steps when a couple cannot conceive. Infertility affects roughly 10-15 % of women of reproductive age, and a tubal factor accounts for a significant share — by many estimates around 25-30 % of female infertility. An HSG is the usual first-line test for tubal patency because it is quick, widely available, and gives information that a scan alone cannot. Where the tubes look open, attention can shift sooner to other parts of the work-up.

When in your cycle is an HSG done, and how do you prepare?
An HSG is timed for the first half of the cycle, usually between day 5 and day 10, after bleeding has stopped but before ovulation. This window avoids disturbing an early pregnancy and gives the clearest images. Preparation is simple: a mild painkiller about an hour beforehand reduces cramping, and you should mention any allergy to iodine or contrast media. The test is not done if there is a chance of pregnancy or an active pelvic infection.
What actually happens during the procedure?
The procedure itself is short, typically lasting only about 5 to 10 minutes from start to finish. You lie on an X-ray table, a speculum is placed as for a smear, and a thin catheter is passed through the cervix to introduce the contrast. As the dye flows, a few X-ray images are taken showing the cavity and the tubes filling and spilling. Most women go home the same day and return to normal activity quickly.
Does an HSG hurt?
Most women feel cramping similar to strong period pain during the few minutes the dye is flowing, rather than the severe pain they often fear. The discomfort usually settles within minutes of the test ending, and a simple painkiller beforehand makes a clear difference. We talk you through each step as it happens and keep the catheter and contrast volume to the minimum needed, because a calm, unhurried test is far more comfortable. Light spotting for a day or two afterwards is normal.
How accurate is an HSG — and what can it miss?
An HSG is a reliable screening test for tubal patency, but it is not perfect, and understanding its limits prevents unnecessary worry. Pooled data from over 4,000 women put its sensitivity at about 65 % and specificity at about 83 % when compared with laparoscopy. Its real strength is ruling blockage out: when an HSG shows open tubes, there is only around a 5 % chance they are truly blocked, giving a negative predictive value near 94 %. The weakness is false alarms — if the test suggests a blocked tube, there is roughly a 60 % chance the tube is actually open, because the muscle at the tube opening can briefly spasm. It can also miss problems outside its view, such as pelvic adhesions, a hydrosalpinx (around 10 %), or some uterine abnormalities, where its sensitivity is closer to 70 %.
| Aspect | HSG performance |
|---|---|
| Detecting open tubes | Strong, NPV around 94 % |
| Confirming a true blockage | Weaker, spasm causes false alarms |
| Sensitivity for tubal disease | Around 65 % |
| Pelvic adhesions / endometriosis | Often missed |

HSG, HyCoSy or laparoscopy — which tubal test is right?
Several tests can check the fallopian tubes, and they are complementary rather than interchangeable. HSG uses X-ray and contrast; HyCoSy (saline-and-foam ultrasound) avoids radiation and also shows the ovaries and uterine wall; laparoscopy looks directly inside the pelvis and is the reference standard but needs anaesthesia. As a rule, HSG or HyCoSy is the first step, and laparoscopy is reserved for when results are unclear or pelvic disease such as endometriosis is suspected. The right choice depends on your history and what else needs checking.
| Test | What it assesses | Note |
|---|---|---|
| HSG (tubal X-ray) | Tube patency, cavity shape | First-line, uses X-ray |
| HyCoSy (ultrasound) | Tubes plus ovaries, uterus | No radiation |
| Laparoscopy | Direct view of pelvis | Reference standard, needs surgery |
Can the HSG itself help you get pregnant?
One of the lesser-known benefits of an HSG is that the act of flushing the tubes can modestly improve fertility for a few months afterwards. In women with unexplained subfertility, flushing with oil-based contrast led to ongoing pregnancy in about 39.7 % of cases versus 29.1 % with water-based contrast, and a five-year follow-up showed higher live birth rates (around 74.8 % versus 67.3 %). This effect is real but specific: it has been shown mainly in unexplained subfertility, not in women of advanced age, with ovulation disorders, or at high risk of tubal disease. We discuss whether oil-based flushing is appropriate for you, rather than presenting it as a treatment for everyone.

What do the results mean: open, blocked, or an abnormal cavity?
HSG results fall into a few clear patterns, and each points to a different next step rather than a fixed conclusion. Open (patent) tubes with a normal cavity are reassuring and move the focus elsewhere in the work-up. A blocked tube needs careful interpretation, since a proximal blockage is often spasm and may be re-checked, while a distal blockage with a swollen tube (hydrosalpinx) is more meaningful. An irregular cavity outline can suggest polyps, fibroids, a septum, or adhesions, usually confirmed with another test.
| Result | What it usually means |
|---|---|
| Both tubes open, normal cavity | Reassuring, look elsewhere |
| Proximal blockage | Often spasm, may re-check |
| Distal blockage / hydrosalpinx | More significant, needs review |
| Irregular cavity | Suggests polyp, fibroid or septum |
Is an HSG safe? Radiation and risks explained
An HSG is considered a safe outpatient test, and its risks are low and manageable. The radiation dose is small — around 2.7 mGy, well within accepted limits and far below the level that would concern a future pregnancy. The main risk is pelvic infection, which occurs in roughly 1-3 % of cases and is reduced by avoiding the test during active infection; an allergic reaction to contrast is rare. Because results can occasionally be falsely abnormal, a single finding is always read together with your history rather than acted on alone.

Our approach to the HSG and your fertility work-up
We see the HSG as one step in a plan, not a verdict, and we build the work-up around that idea. We time the test to your cycle, keep it gentle and brief, and read every result in the context of your full history rather than in isolation. Where the flushing effect of oil-based contrast may help, we discuss it openly; where a result looks like a blockage, we check whether it is simply spasm before drawing conclusions. We keep the same physician with you from the first remote review through to any treatment, so nothing is lost between hand-offs. This work draws on Associate Professor Dr. Cengiz Andan's background in advanced laparoscopic and minimally invasive gynaecology, built over 18 years and more than 2,000 procedures, including over 500 endometriosis surgeries.
Why women travel to Turkey for fertility evaluation
Turkey has become a established destination for fertility care because it combines experienced specialists, modern imaging, and short waiting times in one place. For something as time-sensitive as a fertility work-up, being able to complete the test and discuss the results without months of waiting is a real advantage. The practice of Associate Professor Dr. Cengiz Andan focuses on fertility-oriented, organ-preserving care, with the continuity of one responsible physician guiding the whole process.
Your home country or Turkey — what actually differs?
The honest difference between having your work-up at home or in Turkey is about access and cost, not quality. The same imaging technique and the same international guidelines apply, so the standard is comparable; what changes is shorter waiting, continuity with one physician, and a lower price driven by exchange rates and operating costs rather than corners cut. For many women the deciding factor is simply being able to complete the evaluation in days rather than waiting months for separate appointments.
| Aspect | Your home country | Turkey |
|---|---|---|
| Test quality / standard | Very high | Very high |
| Waiting time | Often long | Usually short |
| Single-physician continuity | Variable | Consistent |
| Cost | Higher | Lower |
After your HSG: results, records and care from home
An HSG rarely causes problems afterwards, and good handover matters as much as the test itself. Mild cramping and light spotting for a day or two are normal, while fever or severe pain are not expected and should be reported. If any concern arises after you return home, we stay reachable and will coordinate with your local doctor so distance never leaves you unsupported. Before you leave, we provide a full English-language report with your HSG images and findings to give directly to your physician, which keeps any onward fertility care seamless.
Planning your visit and follow-up from home
Most of the pathway can begin before you travel. The usual sequence is a remote review of your history and any previous reports, a short visit to Turkey of about 2 to 3 days for the test and a results discussion, and then follow-up handled remotely with your local doctor kept informed. Because an HSG is a brief outpatient test, the time away from home is minimal, and any treatment that the results point to can be planned as a clear next step.
A second opinion before more tests or treatment
A second opinion is often the most useful step when you have been told your tubes are blocked or that IVF is your only option. When you share your HSG images and reports, we review them, check whether an apparent blockage might simply be spasm, and set out the realistic options with you. These reviews run as a paid online consultation and let you clarify your situation before travelling; they do not replace an in-person assessment. You can make first contact easily through the form or WhatsApp, and any related second-opinion topics are explained here in plain terms rather than as separate links.
Frequently Asked Questions
Usually not, as the test is done without general anaesthesia and most women feel well enough to leave on their own. If sedation is used or you feel crampy, it is sensible to have someone with you.
In most cases you can try in the same cycle once any spotting settles. Because tubal flushing may briefly improve fertility, your doctor will advise on timing for your situation.
Light spotting and a watery discharge for a day or two are common and harmless. Heavy bleeding, fever, or severe pain are not expected and should be reported.
An HSG is a short outpatient test, so short flights are usually fine within a day. For longer flights your doctor will give individual guidance based on your recovery.
Most medications can be continued, and a mild painkiller is often advised an hour before. Tell your doctor about any allergies, especially to iodine or contrast media.
Not necessarily. A blockage on HSG can be a temporary spasm rather than a true obstruction, and further tests or surgery may restore an option for natural conception, so results are interpreted in context.
Yes. HSG is a standard part of the fertility work-up regardless of whether you have been pregnant before.
A pelvic ultrasound looks at the ovaries and uterine wall, while HSG specifically shows whether the fallopian tubes are open and outlines the uterine cavity. They give different, complementary information.
Planned treatment abroad is often not covered automatically, and rules vary by country and policy. It is best to ask your insurer directly and request any pre-approval in advance.
Yes. Reviewing your history and previous reports and planning the work-up is done remotely; travel is only needed for the test itself and any treatment that follows.
Most HSGs are done without anaesthesia, using a mild painkiller beforehand. Light sedation can be arranged for anxious patients or sensitive cases.
You receive a full English-language report with the HSG images and findings to give to your local physician for continuous care.
