HSG without anesthesia causes varying pain: many women feel brief, intense cramping when the cervix is handled and contrast is injected, often like strong menstrual cramps; some report moderate to severe pain, but most tolerate it. Discomfort usually peaks during the test and eases within hours; mild cramping or spotting may continue 24–48 hours. Taking an NSAID 30–60 minutes beforehand is commonly recommended.

An HSG exam typically lasts about 15–30 minutes overall. The catheter placement, contrast injection and X‑ray imaging itself usually take roughly 5–10 minutes. Allow extra time for consent, positioning and brief recovery—appointments are commonly scheduled for around 30–45 minutes. The procedure may take longer if additional images are needed or if there are technical difficulties; post‑procedure advice is given before discharge.

Hysterosalpingography (HSG) is usually performed without general anaesthesia; only local anaesthetic gel or a paracervical block may be used and is often included in the procedure cost, so extra anaesthesia charges are minimal or none. If conscious sedation or general anaesthesia is requested, anaesthetist and facility fees vary widely—typically a few hundred to over a thousand dollars (or equivalent). Check with your clinic.

The 10-day rule for HSG means performing the hysterosalpingogram within the first 10 days of the menstrual cycle (commonly days 5–10), before ovulation. This timing lowers the chance of performing the test during pregnancy, reduces infection risk, and provides clearer uterine/tubal imaging after menstruation. Clinics usually confirm a negative pregnancy test and may postpone if infection or active bleeding is present.

Hysterosalpingography (HSG) is primarily diagnostic but can sometimes clear minor fallopian-tube blockages by flushing contrast through the tubes, which may improve fertility in some women. It’s more effective for proximal or functional occlusions than large structural blockages (e.g., hydrosalpinx or severe adhesions). Persistent or major blockages usually need laparoscopy or surgery; there are small risks of pain or infection.

During an HSG the local anesthetic is usually given as a paracervical block — injections of lidocaine into the cervix and paracervical tissues (commonly at 3 and 9 o’clock, or multiple quadrants such as 2, 4, 8 and 10 o’clock). Occasionally topical cervical anesthetic or intrauterine lidocaine is used; general anesthesia is rarely required.
