What is the reason for the large side of the vulva?

The vulva side is large and the other side is small, which may be caused by congenital development problems. Due to the physiological performance of asymmetric growth of labia on both sides in the process of congenital growth and development, normal female health will not cause adverse effects, so no special treatment is needed. If the female labia minora is symmetrical on both sides, suddenly showing a large side of the labia minora, consider more than one side of the labia minora showing edema caused by abnormal performance, there may be in the same room, local long-term friction stimulation caused by labia minora edema, or because of simple vulvitis caused, but also do not rule out this side of labia minora has genital boil caused.
