Use of Theros® FMS Dilators for Vaginismus (Involuntary Vaginal Spasms)

Forget Everything You Know About Dilators

And especially what the word “stretching” brings to mind: probably discomfort or even pain. Time to leave that behind.

FMS Dilators Redefine the Treatment of Vaginismus

FMS stands for “Flexibilisation and Massage System”. This is our term for an alternative, exceptionally gentle approach to releasing vaginal spasms. Unlike conventional dilators, the FMS method is not primarily based on stretching or widening, but on gentle massage that helps release the spasm. The exceptional effectiveness of FMS dilators for vaginismus is based on their unique features and on a very wide range of sizes and sets that can be individually adapted to your needs.

Perfect Functionality and Aesthetics

Theros® FMS dilators are made from high-quality, shatter-resistant borosilicate glass. This material has the smoothest pore-free surface available, creating virtually no friction and none of the compression effect associated with conical silicone dilators. Every dilator is individually handcrafted and mouth-blown, which means there are no seams or edges like those found on industrially manufactured glass dilators. This is why FMS dilators glide so gently. Their unique glide allows even prolonged applications without irritation of sensitive areas.

The special streamlined shape, available in seven variations, prevents compression of the tissue during insertion and ensures maximum comfort.

Certified Medical Device

Theros® FMS dilators are certified medical devices. This guarantees safety of use and confirms their effectiveness.

Shape and Surface Inspired by Nature

FMS dilators are not conical. Instead, they feature an elliptical head and a slightly narrower shaft. This streamlined shape, inspired by nature, does not compress tissue and glides like a fish through water. The almost frictionless surface of borosilicate glass further enhances this exceptional glide. The elliptical head eliminates the need to insert the entire dilator in order to achieve maximum effectiveness. It also allows targeted stimulation of areas deeper inside the body without placing the greatest strain on the vaginal entrance, as is the case with conical dilators whose widest section is at the rear.

All Sizes Are the Same Length

In conventional dilator sets, the slimmer dilators are usually shorter because silicone is not stable enough. Therapeutically, this makes little sense because the slimmer shapes are precisely the ones that can be inserted more deeply and therefore prepare the entire vaginal area most effectively. FMS dilators are all the same length – even the slim sizes can be inserted as deeply as you wish, allowing targeted stimulation of problem areas further inside. They can also be guided precisely because they are dimensionally stable while remaining exceptionally gentle. Guide them yourself and feel the difference. You are in control.

The Right Dilator Set Size

Treating vaginismus requires several dilators – in other words, a dilator set. However, individual anatomy and the symptoms of vaginismus vary greatly. For this reason, we offer sets in many different size combinations. You can also create your own customised set. Before beginning treatment, it is helpful to determine the correct starting size through self-examination. This may feel unfamiliar, but it is the first step towards recovery – and not difficult at all. You can learn how to do this in our Frequently Asked Questions About FMS Dilators. If this is not possible, simply begin with the smallest recommended set.
FMS dilators are available in 27 sizes starting from 14 mm in diameter. If sizes below 14 mm are required at the beginning of treatment, the FMS principle (stretching through massage action) is no longer effective because the difference between the head and shaft becomes too small. In such cases, we recommend our Theros® Bougie Dilators. The polished, pore-free surface glides exceptionally well and is extremely hygienic. Implant-grade steel is 100% biocompatible and suitable even for people with nickel allergies. With an increase of only 1 mm over a length of more than 100 mm, they provide extremely gentle stretching until treatment can continue with FMS dilators from 14 mm onwards.

Our Service: Individual dilators from a set can be exchanged if you ultimately do not need them and they are still sealed.

Proceed as follows: after purchasing your set, first unpack and try the largest dilator (which will naturally not be possible to insert yet), then continue step by step with progressively smaller sizes. This allows you to identify the size that you can insert comfortably. The smaller dilators are not needed. Since they remain sealed when using this method, they can be exchanged.

Preparing for Treatment

Your mental state plays a significant role in treatment success. Therefore, a pleasant atmosphere, peace and sufficient time are important. A positive attitude and conscious deep breathing create additional relaxation. A recommended position for treatment is a semi-reclined, relaxed posture with your legs comfortably apart and slightly bent.

Correct Use

To make insertion even easier, you can warm Theros® FMS dilators (and the supplied anti-allergenic lubricant) in a water bath, as warmth further relaxes the muscles. When filled with tissue paper, FMS dilators can even act as long-lasting heat or cooling bodies. Further information can be found in the instructions for use included with every purchase. After warming, the dilator should be dried. Apply a small amount of lubricant to your vulva and to the tip of the dilator. Then place the head of the dilator at the vaginal entrance and gently attempt to insert it using a slight rotating movement.

It is sufficient for the head to pass the vaginal entrance. Afterwards, simply relax. When you then move the dilator gently back and forth, its elliptical head creates a wave-like movement inside your vagina. Within a set there are different silhouettes that create different forms of stimulation. The FMS method aims to guide the tissue of your vagina out of its “normal state” of spasm by introducing gentle movement. For this reason, you should begin with a very small size in which the stretching effect plays no role at all.

Increasing the Sizes

Once you can move a particular size back and forth without difficulty, you may try the next size. Naturally, you determine the pace at which you increase sizes. Continue in this way until you can comfortably insert and move the largest dilator in your set. If vaginal intercourse with penetration is your goal, you should aim to reach a size of approximately 36 mm at minimum.

FMS dilators are also available in considerably larger sizes should you wish to continue treatment beyond this point.

Simulating Sexual Intercourse

The pore-free, exceptionally smooth surface of borosilicate glass allows prolonged movement without skin irritation. You can gradually increase the intensity of the back-and-forth motion to become accustomed to the movement of a penis inside your vagina. The head of the dilator simulates the glans of the penis. Here too, the advantages of the natural shape of FMS dilators become apparent.

Advanced Use of FMS Dilators

Once the spasms have largely resolved, FMS dilators can also be used in a more advanced way to strengthen the pelvic floor and vaginal muscles. This involves synchronising relaxation and contraction with insertion and withdrawal of the dilator. In other words: consciously relax while inserting the dilator. During withdrawal, hold the head of the dilator firmly for a few seconds using the strength of your vaginal and pelvic floor muscles. This exercise greatly strengthens the pelvic floor muscles, which are important not only for healthy and pleasurable sexuality, but also for preventing incontinence and supporting stability throughout the body.

With a well-trained pelvic floor, you may even be able to “embrace” the glans of the penis during intercourse, which can be highly pleasurable for both you and your partner.

Theros® Vagina Stents – for Long-Term Results

You can significantly support your treatment with Theros® Vagina Stents. Like FMS dilators, they are made from borosilicate glass and offer the same properties. After treatment, simply insert them and wear them during daily life to help make the effects of treatment more permanent.

Before Using Dilators

Self-treatment with FMS dilators can only be helpful if you are psychologically ready for it and genuinely desire a sexual experience involving penetration. An assumed idea of so-called “normal sex” should play no role here.
