Dilators: A Simple and Effective Stretch

Dilators: A Simple and Effective Stretch

by Dr. Barb DePree MD

Even though vaginal dilators have been around for decades, they still elicit lots of attention and a few quizzical looks even from healthcare professionals whenever we display our wares at medical conferences. My patients sometimes have questions, too, and we get phoned-in and emailed questions here at MiddlesexMD.

Dilators are one of the most straightforward medical devices you’ll run across. They are a set of tubes that gradually increase in diameter from about a half-inch to about an inch and a half. They are usually made of high-quality plastic, but may also be made of silicone, which gives them a softer, more flesh-like quality. You can see our list of the best vaginal dilator.


Both types are washable with soap and water. Dilators are used to increase vaginal “patency,”—its capacity and ability to accommodate the things that vaginas are made to do, like a speculum, a baby, a penis—some pretty important stuff, in other words.

Dilators are used to:

  • Prevent scar tissue from forming after some cancers or pelvic radiation therapy.
  • Increase vaginal capacity and length after certain procedures, such as a total hysterectomy.
  • Maintain vaginal capacity during times when sex isn’t an option for whatever reason.
  • Improve vaginal capacity after a long time without sex (remember the old use it or lose it adage).
  • Help to address vaginal shortening and tightening due to hormonal changes of menopause.
  • Treat conditions, such as vaginismus, that make penetration difficult.

Since some vaginal conditions might require additional treatment, such as localized estrogen or muscle relaxants, you should always discuss any vaginal pain or change in your ability to have sex with your doctor, as well as how you might benefit from using dilators. From there, if it’s simply a matter of conditioning or maintenance, our shop has a selection of high-quality plastic and silicone dilators.

I recommend any of these sets. Choose the features and sizes that appeal to you. The first set that we found and offered remains a favorite. It’s available with five or seven dilators, depending on your starting point, and the straight, solid cylinders are easy to handle and clean.

The silicone kit is firm yet flexible with a softer touch. (Bright colors don’t hurt, either.) Be aware that silicone lubes will degrade the surface of these dilators, so use them only with water-based lubricants.

Increasing vaginal capacity takes patience—often several months. For maintenance, you may need to use dilators regularly until you’re having sex regularly. The goal is to accommodate your partner’s penis (or your doctor’s speculum) comfortably and without pain. It’s a worthy goal, so accept that you’re in it for the long haul.

To use dilators:

  • Start with a warm bath to soften tissues and relax your pelvic floor muscles (along with everything else).
  • Find a comfortable and private place and lie down on your back, legs bent at a 45-degree angle and shoulder-width apart.
  • Consciously relax all your muscles, from head to toe. Do a mental scan for areas of tension around your eyes, brows, or anywhere else. Focus on breathing in; breathing out.
  • Begin with the smallest dilator and slather it with high-quality, water-based lubricant. (Not petroleum jelly or any kind of oil.) Generously lube your vaginal entrance as well.
  • Gently insert the dilator until you meet resistance. Pause. Breathe. Practice kegel exercises. Insert it a little farther if you can do this without discomfort. The dilator should fit snugly but without pain.
  • Keep it in place for twenty or thirty minutes. Watch TV or listen to a podcast or your playlist. Practice kegels.
  • You can try rotating it in place or moving it in a circular motion around the vaginal entrance or gently moving it in and out.
  • Clean with soap and water. Towel dry.
  • Move to the next size when you can comfortably insert the smaller one.
  • Do this 3-4 times per week or every other day.

You may bleed a little at first. This is normal. But if you soak a sanitary napkin or experience frequent bleeding, this is not normal. Stop using the dilator and call your doctor.

I like dilators because they’re both simple and effective. Granted, taking a pill is easier, but there are no pills that treat vaginal patency as such. If you stick to the regimen, dilators are very effective in both reconditioning the vagina and in maintaining elasticity during fallow sexual periods.



  • Concerned: Dilators can help achieve more depth of the vagina by putting upward/inward pressure while using the dilators. But there is also a limit to what will be gained there. If this isn’t enough depth to allow for penetrative sex then having your partner use the OhNut ( would be a great solution, designed specifically for this indication.

  • I have been using the dilators and am finally able to get the largest one in. However, even when I’m aroused I can’t get it in more than 4 inches before hitting my cervix. What can I do?

    Concerned on

  • Need Help: Yes, dilators typically are very effective for improving any shortening/narrowing that happens as a result of surgery (usually it is shortening after surgery vs narrowing). You may want to look into lubricant and or vaginal moisturizer for improved comfort as well. There are also products that can improve comfort, such as the Oh Nut It can take time to adjust post surgery, but there are tools to help!

  • I recently had a hysterectomy almost 2 years ago and I still have ovaries. Sex isn’t painful but my husband complains my vagina is narrow and sand paper dry. Will dilators help me widen my vagina ?

    Need help on

  • Windy, Dilators will likely be beneficial. Using a moisturizer in conjunction with the dilators will likely be necessary too. Then the question is about ‘elasticity’, and some women will have the elasticity needed for the stretching required to gain comfort and function, and some women will need treatment to regain that elasticity. The treatment is to re-estrogenize the genitals, with localized estrogen, Intrarosa, or Osphena (all prescriptions to improve the quality of those tissues).
