HSG test concerns from @hallieeeg, fact-checked

What did @hallieeeg actually say?

She went in for a fertility consultation at 26, after eight cycles of trying to conceive without success. During that single visit, she had cycle day three blood work, a complete hormone panel, a transvaginal ultrasound, and her husband's semen analysis all completed. The remaining test is an HSG, which she keeps calling an 'HSD' throughout the video. She's weighing whether to do it next week or wait a cycle, partly because the ultrasound technician told her flat out 'it's not fun.' She also mentions that minor tubal blockages can sometimes be cleared by the procedure, and that conception rates may be higher in the three months following it.

One immediate flag: she consistently says 'HSD' when she means HSG, which stands for hysterosalpingogram. That's not a minor slip. If you're anxious about a procedure, knowing its actual name matters when you're searching for information or asking questions at your clinic.

Does the science back this up?

Mostly yes, with one important caveat. The claim that an HSG can clear minor blockages and temporarily improve conception rates is real, but it's more complicated than a simple fertility boost.

The idea is sometimes called the 'oil contrast medium effect.' Studies using oil-based contrast during HSG have shown a measurable increase in pregnancy rates in the months following the procedure. A significant randomized controlled trial, Dreyer et al. (2017, New England Journal of Medicine), found that women who received oil-soluble contrast during HSG had a 40% cumulative ongoing pregnancy rate at six months, compared to 29% in the water-soluble contrast group. That's a real difference, not noise.

However, many U.S. clinics now use water-soluble contrast, which does not carry the same apparent benefit. So the 'three months after HSG you might conceive easier' claim depends entirely on which contrast medium your clinic uses. Hallie doesn't mention this distinction, and it's a meaningful one. Credit for getting the general concept right, but the nuance matters here.

What did they get wrong (or right)?

The 'HSD' vs. HSG error aside, she actually gets a lot right. Seeking a fertility consult after eight cycles at 26, rather than waiting for the full twelve-month benchmark, is medically defensible. ACOG guidelines recommend evaluation after 12 months for women under 35, but also note that earlier evaluation is appropriate when clinical circumstances warrant it, and many reproductive endocrinologists will see patients sooner.

Her instinct that skipping the HSG leaves a major diagnostic gap is correct. Without it, no one knows if her tubes are open. If all other results come back normal and tubal factor is left unchecked, the workup is incomplete. She's right that waiting could delay answers, not just the procedure.

What she glosses over is pain management. She mentions being scared it will hurt, but doesn't mention that pre-medicating with ibuprofen 400-600mg taken one hour before the procedure is a common and evidence-supported approach to reducing cramping. Leeners et al. (2000, European Journal of Obstetrics and Gynecology) found NSAIDs reduced procedural pain in HSG. Her clinic should be telling her this proactively.

What should you actually know?

If you're in a similar situation, a few things are worth understanding before you schedule or skip an HSG.

• Pain varies widely. Some women report mild cramping, others describe it as significantly worse. Factors include cervical anatomy, anxiety, and whether the radiologist or OB performs it versus a specialized RE. Taking ibuprofen beforehand is not guaranteed to eliminate discomfort, but it's a reasonable step supported by clinical guidance.
• Ask what contrast medium your clinic uses. If they use oil-soluble contrast, the evidence for a short-term fertility benefit after the procedure is stronger. If they use water-soluble contrast, the diagnostic value is still real, but the 'conception boost' effect is less established.
• The procedure takes about 15 to 30 minutes. Most women can drive themselves home, but some prefer to have someone with them given the cramping.
• Skipping it doesn't save you time. If tubal factor turns out to be an issue after you've waited another cycle, you've delayed treatment, not avoided discomfort.

Her anxiety is understandable. But the technician's comment that 'it's not fun' is honest, not a red flag. Most women tolerate it. Getting clear information from your care team about pain management beforehand is the most actionable thing you can do.
