Pelvic organ prolapse is more common than most women realize. In the United States, an estimated 3–6% of women experience symptomatic pelvic organ prolapse, with significantly higher rates among postmenopausal women. Yet many suffer in silence—dealing with pressure, discomfort, urinary leakage, or that unmistakable “bulge” sensation.
Enter Gynecube, commonly known as the Cube Pessary.
This small, soft, silicone device has become one of the most effective non-surgical treatments for moderate to severe pelvic organ prolapse (POP) in the US. It’s FDA-cleared, physician-fitted, and recommended by leading organizations like ACOG (American College of Obstetricians and Gynecologists) and AUGS (American Urogynecologic Society).
If you’re searching for answers about Gynecube in the US (2026 update)—how it works, who it’s for, safety, cost, and alternatives—you’re in the right place.
Let’s break it down clearly and completely.
What Is Gynecube? (Cube Pessary Explained for US Patients)
Gynecube, often referred to as the Gyn Cube Pessary or simply Cube Pessary, is a Class II FDA-regulated medical device used to support pelvic organs that have shifted from their normal anatomical position.
It is:
-
Made from 100% medical-grade silicone
-
Latex-free
-
Soft, foldable, and flexible
-
Designed for vaginal insertion
-
Prescription-only in the US
Unlike ring pessaries, the cube pessary has six concave sides, which create gentle suction against the vaginal walls. That suction is what keeps it securely in place—even in more advanced prolapse cases.
Think of it like a supportive internal brace. Instead of surgery lifting organs back into place, the cube pessary mechanically supports them from within.
In the United States, the cube pessary is particularly popular for:
-
Stage 3–4 uterine prolapse
-
Vaginal vault prolapse after hysterectomy
-
Cystocele (bladder prolapse)
-
Rectocele (rectal prolapse)
More than 500,000 pessary fittings occur annually in the US, making it one of the most widely used conservative treatments in gynecology.
It’s important to clarify something: some online searches mention “GyneCube” as a supplement or digital product. In medical terms within the US healthcare system, Gynecube refers specifically to the cube pessary device.
History and Evolution of the Cube Pessary in the US
Ancient Roots of Pessary Use
Pessaries are not new. In fact, they date back to ancient Egypt around 1850 BCE, where women used natural materials like pomegranate or honey-soaked lint to manage prolapse.
Fast forward thousands of years, and we now have sterile, medical-grade silicone devices engineered for precision and comfort.
Modern Silicone Innovation (1970s–1990s)
The real breakthrough came in the 1970s and 1980s, when silicone replaced older materials like rubber and latex. Silicone is:
-
Hypoallergenic
-
Flexible
-
Durable
-
Biocompatible
-
Easy to sterilize
The cube design was patented in the US during the 1990s, specifically to address more severe prolapse cases where ring pessaries failed.
The cube’s multi-directional support system created a stronger hold—especially helpful in advanced prolapse.
FDA Regulation and US Market Growth
By the early 2000s:
-
Brands like Milex (CooperSurgical) received FDA 510(k) clearance
-
Silicone pessaries became widely available nationwide
-
Professional organizations like AUGS endorsed pessaries as first-line therapy
Today, major US brands include:
-
MedGyn
-
Milex (CooperSurgical)
-
EvaCare
-
Bioteque America
Retail cost typically ranges between $50–$100 per device, though insurance often covers most of the expense.
How Gynecube Works: Mechanism, Insertion, and Effectiveness
How the Cube Pessary Stays in Place
The cube pessary works through a concept called inverse pressure support.
Its concave sides:
-
Create gentle suction against vaginal walls
-
Prevent downward movement of pelvic organs
-
Offer firm support without requiring a support membrane
Some models include drainage holes, allowing vaginal secretions to pass through and reducing infection risk.
Insertion Process (Done by a Healthcare Provider)
In the US, fitting must be done by:
-
A gynecologist
-
A urogynecologist
-
A trained nurse practitioner
Steps typically include:
-
Pelvic examination
-
Vaginal measurement
-
Trial sizing
-
Insertion and comfort evaluation
The device is compressed for insertion and expands once inside.
Patients are usually trained to:
-
Remove it nightly or weekly
-
Clean it properly
-
Reinsert it independently
Follow-ups occur every 3–6 months.
Effectiveness Rates
Clinical studies show:
-
70–90% symptom relief
-
60–80% long-term satisfaction
-
Particularly effective for stage 3–4 prolapse
It may be less necessary for mild prolapse, where ring pessaries often suffice.
For women delaying surgery—or avoiding it entirely—the Gynecube offers substantial relief.
