Technical Tips and Tricks after 10 Years of HyFoSy for Tubal Patency Testing

Area of Science:

• Reproductive Medicine
• Medical Imaging
• Gynecology

Background:

• Hysterosalpingo-foam sonography (HyFoSy) is increasingly utilized for evaluating tubal patency in infertile patients.
• It is recognized as a feasible, well-tolerated, and minimally invasive diagnostic method.

Purpose of the Study:

• To share technical insights and practical tips for performing HyFoSy.
• To enhance procedure feasibility and patient comfort (pain reduction).
• To assess the pregnancy-obtaining rate following HyFoSy.

Main Methods:

• An observational study involving 672 infertile patients undergoing HyFoSy.
• Evaluation of tubal pathway, patency, and patient-reported pain levels.
• A follow-up questionnaire assessed pregnancy rates at 3 months and beyond.

Main Results:

• The median patient age was 33.5 years; 61.16% of procedures occurred between days 8-10 of the menstrual cycle.
• Tubal patency was confirmed in 86% (bilateral) and 11% (unilateral) of cases.
• 75% reported minimal or tolerable pain; 10.86% achieved natural pregnancy within 3 months post-HyFoSy.

Conclusions:

• HyFoSy is a valuable, user-friendly, and largely painless tool for female infertility assessment.
• It complements transvaginal ultrasonography by visualizing tubal patency, regularity, and occlusion.
• HyFoSy should be considered a first-line infertility investigation alongside transvaginal ultrasound.
