The mons pubis is the elevation of the skin in front of the pubic symphysis and is part of the external genitalia of girls. Since puberty, women will have pubic hair growing in the pubic area in the shape of an inverted triangle, covering the surface of the mons pubis, so the mons pubis is not easy to detect. The mons pubis is mound-shaped and its subcutaneous area is rich in fatty tissue, which provides support and reduces vibration during sex. The lower part of the mons pubis is adjacent to the labia majora on both sides, and the surface of the mons pubis is covered by pubic hair, which varies in color and density due to individual differences. Because the pubic mound is covered by pubic hair, it is not easy to clean the pubic mound area, which leads to the growth of bacteria in the pubic hair and the formation of sebaceous cysts in the pubic mound area. Sebaceous cysts are usually 1~2 soybean-sized cystic nodules deep in the pubic mound. The cysts can be present for many years but are not easily detected by the patient, making them susceptible to secondary infections or calcification. If you find odor, itching and other symptoms in the vulva, you should consult a doctor in time, carry out anti-infection treatment, and if necessary, carry out surgical excision to avoid deterioration of the condition.
