Tubal Patency Studies
A new contrast agent (ExEm Foam) has been registered with the TGA for the purpose of tubal patency testing with
ultrasound. This replaces the obsolete Levovist for hystero-colpo-salpingography (HyCoSy) and the procedure is otherwise unchanged.
ExEm is a non (embryo) toxic gel foam containing glycerol and hydroxyethylcellulose that has been tested extensively
and safely used in medicine (Elam and Elam. 1993; Fale et al., 1998; O’Brien et al., 2003; Berger et al., 2005; Nilforoushan et al., 2005). ExEm gel foam was successfully trialled in the Netherlands
for office tubal patency testing achieving adequate uterine cavity filling in 92% of patients (Emmanuel et al, Human Reproduction Nov. 2011) with no serious side effects observed overall. 7% of
patients experienced vasovagal discomfort that resolved spontaneously.
We hope to continue to serve those in need of fertility investigations and your patients will be sheduled for
ExEm foam salpingogram during days 4 - 10 of a regular menstrual cycle by our reception staff.
