Hi all. In an excellent discussion, Dr. Pacik describes the glass dilators: “These dilators are made of a pyrex-like material. Vaginal dilators are often the first attempt at treating vaginismus for those women who are able to tolerate some penetration. Many companies make vaginal dilators, but typically as you get to the larger sizes, the dilators are made too long and protrude from the vagina. The glass dilators are all the same length, 3 1/2 inches (the average depth of the vagina), which allows the woman to be mobile during dilation, and range in size from the #3 (about the size of the index finger) to #6 (#’s 5 and 6 are the usual sizes needed to progress to intercourse). #7 and #8 is helpful for women with larger partners.”
