The degree of tightness after shrinkage surgery is different for different women, because it is affected by women’s age, the number of births, habits and other factors, and should be analyzed on a case-by-case basis. Firstly, for women under 25 years old who have not given birth and are in good health, the degree of tightness after the reduction surgery is relatively large, which is related to women’s young age or muscle contraction; secondly, for women between 25-35 years old, their vagina can become relatively tight after the reduction surgery, but the degree of tightness will not be too great; thirdly, for women between 35 years old, their vagina can become relatively tight after the reduction surgery. Thirdly, for women over 35 years old, even after the surgery, the vagina will not be too tight, which is related to the age of women and the decrease of muscle contraction; fourthly, the degree of tightness after the surgery is also related to the surgical technique and the perfection of the surgery.
