There are three main ways to shrink the vagina: firstly, to shrink the pelvic floor muscles by doing exercises to shrink the pelvic floor muscles, which will help the vaginal wall muscles to shrink and recover, which is more effective for women with mild vaginal laxity. Secondly, special pelvic floor rehabilitation treatment, which takes about a month, and is most effective when performed within six months after delivery. Thirdly, the fastest way to shrink the vagina is vaginal tightening, which is also known as anterior and posterior vaginal wall repair. For women within six months after childbirth, vaginal reduction surgery is not preferred, but rather anal reduction exercises and pelvic floor rehabilitation should be done.
