Consider the vagina is a rubber tube. If the rubber tissues are very elastic, stretching would not enlarge the vaginal size or orifice. The elasticity of the muscles depend on the testosterone and DHEA level in the local tissues.
Vaginal exercise, massage and stimulation can bring more testosterone and DHEA to help develop the hormonal receptors in the local tissues, leading to improvement of sexual and orgasmic responses, if the female bloodstream has a high level of testosterone and DHEA.
That is why in conjunction with the Finger Plier Method, we have developed ViaGrowth-III and -IV for young and middle-aged/sensior women, respectively to replenish their testosterone and DHEA level and to optimize their estrogen level for the best sexual and orgasmic responses.
