HyCoSy (Fallopian Tube Patency Test) in Chennai

HyCoSy, or hysterosalpingo-contrast sonography, is a safe and effective ultrasound-based test that assesses the patency (openness) of the fallopian tubes while evaluating the uterus and surrounding pelvic structures. By injecting a harmless contrast medium into the uterus, HyCoSy allows real-time visualization of how the fluid flows through the fallopian tubes, identifying blockages that could impact conception.

This radiation-free alternative to traditional X-ray HSG takes about 20-30 minutes and provides immediate preliminary results.

Why is HyCoSy Performed?

The HyCoSy procedure is a key diagnostic tool in fertility assessments, commonly recommended for:

  • Evaluating unexplained infertility: Tubal factors account for up to 30% of infertility cases
  • Investigating recurrent pregnancy loss: Potentially linked to tubal adhesions or blockages
  • Pre-IVF assessment: Checking fallopian tube openness before assisted reproduction
  • Detecting hydrosalpinx: Fluid-filled tubes that may need treatment before IVF
  • Monitoring pelvic health: In women with history of pelvic inflammatory disease or endometriosis

How to Prepare for Your HyCoSy Procedure

  • Cycle Timing: Schedule for days 7-12 of your menstrual cycle (after period ends, before ovulation)
  • Pregnancy Precautions: Avoid unprotected intercourse from period start until after procedure
  • Pain Management: Take ibuprofen (600mg) or paracetamol 30-60 minutes before
  • Infection Screening: Recent chlamydia/gonorrhea test results required (within 6-12 months)
  • Hygiene: Empty bladder before procedure; bring a sanitary pad

The HyCoSy Procedure: Step-by-Step

1 Baseline Scan: Transvaginal probe images uterus, ovaries, and tubes
2 Speculum Insertion: Cervix visualized and cleaned
3 Catheter Placement: Thin catheter inserted through cervix
4 Contrast Injection: Saline with air bubbles/foam injected
5 Real-Time Imaging: Ultrasound captures contrast flow through tubes
6 Completion: Catheter removed; remaining contrast drains naturally

Frequently Asked Questions

How does HyCoSy differ from HSG?

HyCoSy uses ultrasound and saline/air contrast without radiation, while HSG relies on X-rays and iodine dye. HyCoSy is gentler, done in the clinic, and equally accurate (89-97%). HSG may be preferred if detailed tubal anatomy is needed.

Is HyCoSy painful?

Many women feel mild period-like cramps during the procedure. Taking ibuprofen 30-60 minutes before helps significantly. Severe pain is uncommon (under 10%). The discomfort typically resolves within minutes.

Can HyCoSy improve pregnancy chances?

Yes, studies show the contrast may flush minor debris from tubes, with higher spontaneous pregnancy rates in the 6 months post-procedure. This "tubal flushing" effect is a bonus benefit of the test.

What if the test shows blocked tubes?

Options include surgical repair (tubal surgery), IVF bypass, or further laparoscopy for confirmation and treatment. Our team customizes the approach based on your age, fertility history, and goals.
