Private Fertility Imaging in Central London

All care is delivered in a private, consultant-led setting in the City of London, with clear explanation, gentle technique, and immediate interpretation.
What is Tubal Patency Testing (HyCoSy)?
HyCoSy is a specialised transvaginal ultrasound procedure used to assess whether the fallopian tubes are patent (open).
During the test:
-
A fine catheter is placed through the cervix
-
Ultrasound contrast fluid is gently introduced into the uterus
-
Real-time ultrasound tracks the flow of contrast through the fallopian tubes
Free flow of contrast indicates tubal patency; delayed or absent flow suggests blockage.

-
Are undergoing fertility investigation
-
Have unexplained infertility
-
Are planning assisted conception (e.g. IUI or IVF)
-
