The labia are the external genital organs of women, divided into the labia majora and labia minora, covering the vaginal opening can effectively stop bacteria and viruses from the vulva from entering the vagina and play a role in protecting the vagina. The reasons for the labia to become longer: First, it may be due to repeated friction during sexual life, which leads to the appropriate labia to become longer. Secondly, it may also be due to the laxity of the skin in the labia area as we age, which leads to the lengthening of the labia. Moderate labial elongation does not affect sexual life and will not lead to urethral inflammation or vaginal inflammation. If a woman’s labia grows more, making urine stay may also lead to vulvar and vaginal infections. Women can be given lotions to cleanse and, if necessary, surgery to partially remove the excess labia can also help alleviate the condition.
