Labiaplasty is a surgical procedure that reduces the size of the labia minora. The labia minora lay inside the labia majora and along either side of the vaginal opening. Childbirth, massive weight loss, aging, or genetics can cause the labia minora to become enlarged, stretched, asymmetrical, darkened, or a combination of these characteristics. This can lead to physical discomfort during intercourse, exercise, or while wearing certain types of clothing, as well as self-consciousness regarding the appearance of the labia minora.
