Saline Infusion Sonography (SIS) / HyCoSy

Saline Infusion Sonography (SIS) and HyCoSy are specialized ultrasound procedures used to evaluate:

Uterine cavity (polyps, fibroids, adhesions)

Fallopian tube patency (especially in HyCoSy)

A sterile saline or contrast medium is gently introduced into the uterus to provide clearer imaging.

Why it matters:
It plays a crucial role in fertility assessment and helps identify causes of infertility or recurrent pregnancy loss.
