Abrstract
Infertility affects up to 10% of couples in the Western World and 20-40% may be due to tubal disease. This is commonly the result of previous infection or surgery. Hysterosalpingo-contrast-sonography (HyCoSy) is a transvaginal ultrasound technique in which a solution of galactose (Echovist) or galactose and 1% palmitic acid (Levovist) is infused into the uterine cavity and observed to flow along the fallopian tubes or spill locally into the peritoneal cavity to assess tubal patency. In recent years HyCoSy is increasingly being used in preference to hysterosalpingography and laparoscopy as a first line investigation for infertility because of its convenience and safety. HyCoSy also allows examination of the other pelvic organs and because it is a dynamic study can give valuable information regarding tubal function.
