What Are Dilators and How Do They Work?

What Are Dilators?

Vaginal dilators, sometimes referred to as vaginal trainers or pelvic floor trainers, are a common tool used in pelvic floor therapy to restore healthy pelvic floor function and decrease pain and tension.

Dilators have a tube or cylinder-shaped shaft with a rounded or cone-shaped end and are typically made of silicone or hard plastic. They usually come in sets of varying sizes and widths to assist in lengthening the vaginal soft tissue over time.

How Do Dilators Work?

Dilators work to improve tolerance to touch, stretch, and penetration by relaxing muscles and calming the nervous system. As a dilator assists in increasing tissue flexibility, a larger dilator may be used until the desired outcome is achieved.

It is best to start dilator therapy with the smallest dilator in your kit and then progress in size as able, based on comfort.

Why Use Dilators?

Vaginal dilators can be used as part of a pelvic therapy program for individuals that suffer from painful penetration or vaginal discomfort. Common diagnoses that identify a person may benefit from dilator training include: Vaginismus, Vulvodynia, painful or restricted scar tissue, Vaginal Atrophy, Vaginal Stenosis, Dyspareunia, Post Radiation or Cancer Treatment, and general pelvic floor tension.

How to Use Dilators?

Before beginning a new vaginal dilator training or therapy program always consult a pelvic medical professional. A medical professional such as a Pelvic Physical Therapist can create an individualized training program to enhance treatment outcomes.

A general vaginal dilator training program consists of using your dilators 3 to 5 times per week for 10-20 minutes and should always include breath work. Breathing is directly related to our pelvic floor movement and is important to be aware of as you use your dilators. Staying calm and focusing on your breath will improve the outcome and use of the dilators. Learn more with How to Use Dilators.

Throughout a vaginal training session you should be relaxed and have very minimal to zero pain and discomfort. Using dilators may become painful if they are inserted too far or if an incorrect size is used. If this happens, stop and breathe in and out slowly for a few minutes then continue.

Always start with the smallest dilator first and consult your pelvic physical therapist or pelvic medical professional for further instruction. The use of a dilator should be completely pain free and comfortable before progressing to a larger size. Continue to How to Use Dilators for step by step instructions.
