Vaginoplasty is a procedure that aims to "tighten up" a vagina that's become slack or loose from vaginal childbirth or aging. Some surgeons claim it can even improve sensitivity -- a claim the American College of Obstetricians and Gynecologists (ACOG) has strongly challenged. While it's true that vaginal tissues can stretch, surgically tightening the vaginal tissue in itself cannot guarantee a heightened sexual response, since desire, arousal, and orgasm are complex, highly personal responses, conditioned as much by emotional, spiritual, and interpersonal factors as aesthetic ones. In addition, sexual "sensitivity" doesn't automatically lead to more pleasure - it can actually lead to pain. Labiaplasty, plastic surgery on the labia (the “lips" surrounding the vagina), can be performed alone or with vaginoplasty. Surgery can be performed on the labia major (the larger, outer vaginal lips), or the labia minor (the smaller, inner vaginal lips). Labiaplasty changes the size or shape of the labia, typically making them smaller or correcting an asymmetry between them.
