HSG (Hysterosalpingography) is a widely used fertility imaging test that evaluates two critical factors for natural conception and treatment planning:
whether the fallopian tubes are open, and
whether the uterine cavity has a normal shape.
For many patients exploring Cyprus IVF, IVF in North Cyprus, or a Cyprus fertility clinic, HSG is often one of the first investigations recommended—especially when pregnancy has not occurred after regular attempts or when infertility has no clear explanation.
HSG is an X-ray–based test performed using a special contrast fluid. During the procedure:
A thin catheter is placed through the cervix.
Contrast dye is gently introduced into the uterus.
X-ray images track how the dye fills the uterine cavity and whether it passes through the fallopian tubes.
If the dye flows freely into the abdominal area, the tubes are generally considered patent (open). If the dye does not pass, it suggests a possible blockage or tubal spasm.
Even before IVF, understanding the condition of the fallopian tubes and uterine cavity helps determine the best and fastest route to pregnancy.
Is natural conception realistic, or is treatment needed?
Is IUI (insemination) worth trying, or would it be time loss?
Should IVF be recommended due to tubal factor infertility?
Is there a uterine cavity issue that might affect embryo implantation?
In many Cyprus IVF center treatment pathways, HSG is a valuable “roadmap test”—helping your team avoid unnecessary delays and tailor the most appropriate approach.
One-sided blockage (one tube closed)
Two-sided blockage (both tubes closed)
Hydrosalpinx (fluid-filled tube), which can negatively impact implantation in IVF
HSG may suggest:
Uterine shape differences (congenital variants)
Filling defects that may be compatible with polyps or fibroids
Adhesions (scar tissue)
Important note: HSG is excellent for tubal evaluation, but if a uterine cavity issue is suspected, additional testing (such as hysteroscopy) may be recommended for confirmation and treatment planning.
HSG is commonly considered in these situations:
Unexplained infertility
Suspected tubal factor infertility
History of pelvic infection or sexually transmitted infections
History of endometriosis (in selected cases)
Previous ectopic pregnancy
Previous pelvic or abdominal surgery
Planning IUI (since IUI requires at least one open tube)
Prior to deciding between IUI vs Cyprus IVF
If you are directly proceeding to IVF, your doctor may still recommend HSG or an alternative tubal assessment—especially if hydrosalpinx is suspected.
HSG is usually scheduled after menstrual bleeding ends but before ovulation, commonly around:
Cycle day 6 to day 12 (varies by clinic protocol)
This timing helps ensure:
You are not pregnant during the test
The uterine lining is thin for clearer imaging
Infection risk is minimized
While protocols vary, the general process is:
Preparation
You may be asked about infection history and pregnancy risk.
Some clinics recommend mild pain relief beforehand.
Positioning
You lie in a gynecological exam position similar to a smear test.
Catheter Placement
A speculum is inserted, and a thin catheter is placed through the cervix.
Contrast Injection + Imaging
Contrast fluid is slowly injected.
X-ray images are taken to visualize uterus and tubes.
Completion
The catheter is removed.
You may rest briefly and then go home.
The procedure itself typically takes only a few minutes, though total time at the clinic may be longer.
Pain perception varies. Many patients describe:
mild to moderate cramping (period-like), especially when dye is injected
brief discomfort that improves quickly afterward
Pain may feel stronger in cases where:
the cervix is sensitive,
the uterus contracts strongly,
a tube is blocked (or spasms).
Clinics may recommend individualized comfort measures. If you have anxiety about the test, discuss options in advance.
HSG is generally safe when performed by experienced teams, but possible issues include:
Cramping
Light spotting
Mild dizziness or discomfort
Infection (risk is higher in those with prior tubal infection)
Allergic reaction to contrast (rare)
Vasovagal response (faintness)
You should seek medical support if you experience:
fever,
increasing pelvic pain,
heavy bleeding,
foul-smelling discharge.
Some couples conceive naturally after HSG, especially when mild debris or mucus is cleared from the tubes during the test. This is not guaranteed, but it’s one reason HSG is sometimes described as having a potential “tubal flushing” effect.
However, the main value of HSG remains diagnosis and treatment planning—particularly for deciding whether IUI is reasonable or whether IVF in Cyprus is a better next step.
Typical result categories include:
Normal: Uterine cavity normal; both tubes open
Unilateral blockage: One tube open, one blocked
Bilateral blockage: Both tubes blocked (often directs toward IVF)
Possible hydrosalpinx: may require further evaluation before embryo transfer
Uterine cavity irregularity: may require hysteroscopy or detailed imaging
Because tubal spasm can mimic blockage, doctors sometimes recommend repeat evaluation or alternative tests if findings are borderline.
Depending on your case and clinic approach, alternatives may include:
HyCoSy / contrast ultrasound (tubal assessment via ultrasound with contrast)
Saline infusion sonography (uterine cavity evaluation; less about tubes)
Laparoscopy with dye test (more invasive but can diagnose/treat simultaneously)
Your fertility plan in a Cyprus IVF clinic may use HSG or a suitable alternative based on your history and available imaging options.
If HSG shows:
both tubes blocked → IVF is usually the most efficient path
hydrosalpinx → tube management may be recommended before embryo transfer
normal tubes but infertility persists → IUI or IVF may be chosen based on age, ovarian reserve, sperm quality, and time trying
For international patients traveling for Cyprus IVF treatment, completing HSG (or an approved equivalent) before arrival can help reduce time on-site and allow faster planning.
HSG (Hysterosalpingography) remains one of the most important first-line fertility tests because it answers a key question: Are the tubes open and is the uterine cavity likely suitable for implantation?
For patients considering Cyprus IVF or evaluating the best fertility treatment path, HSG can clarify whether IUI is realistic, whether IVF should be prioritized, or whether uterine/tubal issues need to be addressed first.
