tilted Eupho Syn product with The New Standards title
In 2002, Aneros released the world’s first hands-free prostate massager, an anatomically-configured product specially balanced to work in harmony with a user’s contractions. In the years since, millions of men have been introduced to the concept of prostate pleasure and the wonders of the Male G-Spot orgasm. In late 2017, we released the Trident series. These devices introduced MAMA™ balancing architecture and a new arm configuration that demonstrated a tremendous improvement in product performance. The public response in 2018 was overwhelming, making it clear a milestone had been reached. Going forward, we will be incorporating these design elements into our existing product line as well as our new products, establishing a new standard now and for years to come.

How It Works

Prostate Massage Finger Medical Illustratration
The Old Way

Before the Aneros Stimulator, prostate massages always involved someone performing the massage, whether it be a physician during a check up, body work therapist, or if lucky, a skilled partner. Providing an effective massage is definitely an acquired skill. Due to flexibility constraints, realizing the benefits of an effective self-massage for most men has not been possible.

The Aneros Way

The Aneros Stimulator allows men to self-administer a prostate massage comfortably and discreetly. Simply through anal kegel exercises, the Aneros’s design utilizes a self-pivoting mechanism that stimulates the prostate internally and external via the perineum. This is done completely hands free, allowing a user freedom to explore the sensations in any number of positions.

Contract for Pleasure

When a man contracts his anal sphincter muscles, the perineum tab acts as a fulcrum against which the Aneros Stimulator pivots, massaging the prostate for incredible sensations. Completely hands-free, the Aneros can be used in any position the man chooses.


The Super O Icon
Reach the Super- O

Using the Aneros Stimulator is progressively rewarding. Every session builds on the previous, increasing your body’s understanding of the sensations it has experienced, and incorporating new ones. Through practice and exploration, a user can reach the pinnacle of body/mind pleasure called the Super-O.

Better Sexual Health

Using the Aneros Stimulator will gradually strengthen a man’s pelvic floor muscles and PC sphincter muscles. Over time this results in better sexual performance and ejaculation control. Think of it as exercise to improve your overall sexual health and vitality.

Better Sex & Orgasms

During sex, the man’s thrusting motions automatically cause the Aneros to stimulate the prostate and anal cavity. This gives the man anal, prostate and penile pleasure at the same time – a sexual trifecta! At climax, the prostate stimulation results in a stronger, more satisfying orgasm.


Don’t Forget Lubricant!

The key to getting the most enjoyment from the Male G-Spot is applying a liberal amount of lubricant. This allows the Aneros Stimulator to be inserted comfortably and to move freely during use. We recommend using only water-based lubricants because of the ease of clean up after use. Water-based lubricants also will not breakdown silicone which is used on some of our products. Our Sessions and Marksman water-based lubricants have been specially formulated for anal use

History of Aneros Eupho Syn Trident Prostate Massager

The history of the Eupho Syn Trident began with the release of the original Eupho in 2004, as a part of the launch of Aneros’ “New Generation Line” of products. The release of these products signaled a departure “ from the one size fits all approach” of the Aneros MGX in favor of a specialized series of products, intended to meet user preferences. With this transition, the Aneros product line grew from one model to four. With its ultra-sleek profile and smaller head, the Eupho was introduced to the public as an advanced user model, because it required more developed muscle tone to gain the most benefit from it. In 2012, Aneros released the Eupho Syn, a hybrid version of the Eupho featuring a rigid substrate overcoated in soft silicone. A more luxurious edition, well-known for its super ease of insertion, it quickly eclipsed the Eupho in sales. In 2017 the “New Generation Line” was revamped and rebalanced using a new, MAMA® (multi-axial-motion) architecture. In addition to a different symmetry this new version featured a new tab (replacing the removal handle) . The result was more movement in 3 axial planes, more responsiveness and greater internal and external stimulation. And so, the Helix Trident was born. In 2019, a Trident version of the Eupho Syn was released. Since that time the Tridents have received rave reviews and many industry awards.

Features of Aneros Eupho Syn Trident Prostate Massager

The Eupho Syn Trident is a 4th generation anatomically designed hands-free male G-spot stimulator, combining the design elements from our most specialized model, the award-winning Eupho Trident with the added comfort of our velvet touch silicone. With a simple contraction the Eupho Syn Trident pivots inward and upward stimulating the male G-spot (prostate), anus, perineum and K-spot simultaneously. The Eupho Syn Trident features a lithe, sculpted body, with a small .70-inch rounded head, .98-inch midsection and a 3.85-inch insertable length. Flexible K and P tabs and arms produce more gentle external stimulation. The Helix Syn is made of FDA approved, phthalate free, non-porous materials, so it’s safe to use and easy to clean. The Eupho Syn Trident can only be used with water-based and plant oil based personal lubricants.

Why the Aneros Eupho Syn Trident Prostate Massager

The Aneros Eupho Syn Trident has been widely praised as the most agile model in the Aneros product line. Known for its subtle level of stimulation and the utmost mobility, it was originally regarded as an advanced user device only, since it typically requires a higher degree of muscle tone to generate sustained movement out of the device and the best performance. Advanced users commonly refer to the head of Eupho Syn Trident “dancing all over the surface” of their prostates producing a powerful, qualitatively different kind of orgasm as a result. More recently, the Eupho Syn Trident has become established as a “new user” model as well. For folks who are new to Aneros products or anal play in general, the Eupho’s minimally invasive slim profile and small head make it a perfect “ice breaker”. Similarly, it’s terrific as a couples device. Whether it’s during intercourse or any kind of lovemaking, with the Eupho Syn Trident inside, any and all movements of the body, voluntary or involuntary are instantly transformed into a gentle stroking stimulation of the prostate. Used in this way, the Eupho Syn Trident is essentially an erotic amplifier, transforming the typical sexual encounter into a unique sensory experience. The results are stronger and longer orgasms with much greater volume of ejaculate. Flexible K and P tabs and arms produce most comfortable external stimulation, perfect for sitting and grinding, stepping out on the town or sleeping.
