HSG Procedure Facts and Benefits for Fertility Evaluation
A 2017 Dutch study in the New England Journal of Medicine found that HSG with water-based contrast increases live birth rates by 28% for unexplained infertility. The procedure, which takes less than a minute, uses low-pressure catheters to minimize discomfort and exposes patients to radiation equivalent to a dental x-ray. Most patients report less cramping than menstrual pain.
Key Takeaways
Water-Based Contrast Improves Pregnancy Rates
Research shows water-based contrast used in HSG increases live birth rates by 28% for unexplained infertility. This makes HSG not just a diagnostic tool but a potential fertility treatment itself.
Low Radiation Exposure and Safety
HSG exposes patients to radiation levels comparable to a dental x-ray. It does not harm ovaries or organs and is non-toxic to the body.
Low-Pressure Catheters Reduce Discomfort
Shady Grove Fertility uses specialized low-pressure catheters, reducing procedural pain compared to standard methods. Most patients describe the experience as less uncomfortable than menstrual cramps.
Preventive Measures for Cramping
Taking ibuprofen 1 hour before the procedure on a full stomach is recommended to minimize cramping. This practice is standard at Shady Grove Fertility clinics.
Rare but Critical Complications
Severe pelvic infections occur in less than 1% of cases. Patients with contrast allergies must inform providers pre-procedure, and post-HSG intercourse is restricted for 24 hours to prevent infection.
