Vulvar ectropion occurs when a girl enters puberty. When a girl enters puberty (10-18 years old), due to the influence of sex hormones, the girl’s vulva will develop from a young girl to a mature female accordingly, and from the appearance it seems like the vulva appears to be ectopic. The vulvar tissues of mature females are elastic and rich in blood flow, and all the normal organs of the vulva, such as the labia majora and labia minora, can be seen directly. If you enter the period of puberty, if the sex hormone secretion in your body is normal, besides the development of vulva to maturity, there should also be the development of other secondary sexual characteristics of women, such as the gradual increase of breast, pubic hair, axillary hair, subcutaneous fat gradually full, etc. Insufficient secretion of sex hormones in the body can cause dysplasia of the vulva. It is important to note that if a girl reaches puberty until she is 18 years old, not only is her vulva not turned out, but she also does not have menstruation, she should go to the hospital in time to find out the cause.
