HSG (Hysterosalpingography) in Turkey: The First and Most Vital Step in Your Fertility Journey
What is an HSG test? Is it painful? Learn about checking fallopian tube patency, the fertility-boosting “flushing effect,” and the painless procedure process in Istanbul with Dr. Cengiz Andan.
Mapping Your Path to Parenthood
You’ve decided to have a baby, but despite your efforts, you haven’t seen that positive result yet. After initial blood tests and sperm analysis, the most critical diagnostic test your doctor will request is usually Hysterosalpingography (HSG), commonly known as the “dye test” or “uterine film.”
Many women fear this procedure due to outdated stories of pain. However, with modern technology—digital C-arm X-ray machines and soft catheters—HSG has become a procedure that takes only seconds, is painless or causes minimal discomfort, and is extremely comfortable.
At Dr. Cengiz Andan’s Clinic, we view HSG not just as a diagnostic tool, but as the beginning of your treatment. By creating a detailed map of your uterus and tubes, it shows us exactly “which path to take” to help you conceive.
- What is HSG? How Does It Work?
HSG is a specialized X-ray procedure used to evaluate the shape of the uterine cavity and check whether the fallopian tubes are open. On a standard X-ray, the uterus and tubes are invisible. To make them visible, a “Contrast Medium” (an iodine-based fluid) is gently introduced through the cervix. This fluid fills the uterus, travels through the tubes, and spills into the abdominal cavity. X-ray images are taken in real-time to watch the flow. The entire process takes only 5-10 minutes.
- When and Why is HSG Recommended?
HSG is indispensable in infertility investigation. It is mandatory in the following situations:
- Infertility Assessment: It is the only non-surgical way to know if the fallopian tubes—where sperm meets egg—are blocked.
- Recurrent Miscarriages: To investigate structural issues like a uterine septum, adhesions (synechiae), fibroids, or polyps that prevent implantation.
- Before IVF: To rule out hydrosalpinx (fluid-filled tubes), which can leak toxic fluid into the uterus and lower IVF success rates.
- After Tubal Surgery: To check the status of the tubes after ectopic pregnancy surgery or tubal reversal.
- How is it Performed? Step-by-Step
The procedure is usually scheduled 2-3 days after your period ends (before ovulation occurs).
- Preparation: You lie on a gynecological exam table (lithotomy position).
- Catheter Placement: A very thin, soft cannula is placed at the opening of the cervix. (Old-fashioned metal instruments are rarely used now, minimizing pain).
- Imaging: Contrast fluid is slowly released. You might feel a mild fullness similar to menstrual cramps. X-ray images are taken simultaneously.
- Completion: Once finished, you can stand up immediately.
- The “Therapeutic” Power of HSG: Does it Increase Pregnancy Chances?
Yes, it does. HSG is not just a diagnostic test. As the fluid flows through the tubes under pressure, it can “flush out” small mucus plugs, cellular debris, and mild adhesions. This is medically known as the “Flushing Effect.”
Scientific Evidence (The H2Oil Study – NEJM, 2017): A study published in the prestigious New England Journal of Medicine found that particularly when oil-based contrast is used:
- Spontaneous pregnancy rates within 6 months were 39.7% in the oil-based group.
- Compared to 29.1% in the water-based group. This means the first 6 months after the procedure is a “Golden Period” for conception.
- How Accurate is HSG?
HSG has a high accuracy rate, though not 100%.
- For Tubal Patency: It has a sensitivity of 65-85%.
- False Blockage (Tubal Spasm): sometimes, due to anxiety or the fluid sensation, the uterus contracts, and the tube openings clamp shut. The tubes may look “blocked” on the film even though they are open. This happens in about 10-20% of cases.
- Important: If your HSG shows blocked tubes, don’t lose hope immediately. Dr. Andan may recommend a Laparoscopy (camera surgery) to confirm the diagnosis definitively.
- Risks and Side Effects
HSG is an extremely safe procedure. The complication rate is less than 1%.
- Mild Pain: Brief cramping during the procedure.
- Spotting: Mild bleeding for 1-2 days is normal.
- Infection: Very rare. Antibiotics may be given as a precaution.
- Allergy: Rare reaction to the iodine contrast.
Frequently Asked Questions (HSG)
- Do I need anesthesia for HSG?Answer:With new-generation soft catheters and digital machines, anesthesia is usually unnecessary; the sensation is like a pinch. However, for patients with vaginismus or very low pain tolerance, the procedure can be performed comfortably under “sedation” (twilight sleep).
- When can I have sex after the procedure?Answer:To prevent infection, we usually recommend avoiding intercourse for 2-3 days. After that, regular intercourse is encouraged, especially to take advantage of the “flushing effect” on fertility.
- Can HSG unblock tubes?Answer:If the blockage is caused by mucus plugs or very mild debris, the pressure of the fluid can open them. However, if there is a solid blockage, severe scarring, or hydrosalpinx, HSG cannot fix it; surgery or IVF will be needed.
- Will the radiation harm my eggs?Answer:No. The radiation dose during HSG is extremely low and does not damage your ovarian reserve or egg quality.
- Can I get my results immediately?Answer:Yes. The images appear on the screen instantly. Dr. Cengiz Andan will interpret them right away, explain the condition of your uterus and tubes, and map out your treatment plan.
