Ring Pessary Without Support: Sizes 0-9, Benefits & How to Choose
The classic open ring pessary
The ring pessary without support is the most widely used pessary shape in the world: a flexible ring of 100% medical-grade silicone that supports the vaginal walls and pelvic organs without a membrane. It is often chosen for uterine prolapse and mild bladder prolapse, and it is the easiest type to insert, remove and clean, which is why many clinicians start patients on it.

With support or without?
Choose the ring with support if you also have a cystocele (bladder bulge), its membrane supports the front vaginal wall. Choose without support for uterine prolapse or when your clinician recommends an open ring. Not sure of your size? The Fitting Combo Without Support (2 sizes, $89.99) or the Fitting Pack (3 sizes, $129.99) lets you try sizes at home instead of guessing.
