With the development of medicine, it has changed from the original pure biomedical model to a new bio-psycho-social model, from a simple treatment for diseases to a group health care, prevention and active participation of people. The physical and mental health of childhood is the key period that determines the physical fitness and physique of a lifetime. Due to the characteristics of female reproductive organs, the prevention of their specific and non-specific inflammatory diseases is of great importance, and the development of good health habits from an early age is a strong guarantee of maintaining physical and mental health, happy work and family happiness at all stages of later life. Here we will talk about the health care of reproductive organs in different periods of children’s growth and development. Infancy: Infancy is the period of the fastest physical and intellectual development, while the reproductive organs are basically in a childish state. The health care of reproductive organs in this period is to pay attention to vulva hygiene. Parents should pay attention to the following matters: 1. Parents must pay attention to personal hand hygiene before giving care to the baby, cut short nails to avoid scratching the baby’s skin 2. Babies should have special bath tubs, hand towels and bath towels 3. The urethral opening, vaginal opening and around the anus, gently wipe dry the labia and skin folds 6, keep the vulva skin dry, especially the folds, not too much powder, so as not to enter the vagina, forming small clumps and irritation. Some parents say that we have done all of the above, why do labial adhesions still occur? If parents do not use their fingers to separate the two labia majora when cleaning, they cannot clean the vulva, and the vulva and vestibular mucosa will become flushed and congested, and vulvovaginitis will occur, and the inflammatory stimulation will cause the epithelium of the delicate and thin labia minora to fall off and form a trauma, and when the trauma heals, the connective tissue will extend to the opposite side, resulting in bilateral labia minora adhesion. This leads to bilateral labia minora adhesions. The youngest labial adhesions we see clinically are only 3 months old, and most of them occur from 7~8 months to 2 years old. Childhood: Among pediatric gynecological diseases, vulvovaginitis is a common disease. Poor local hygiene is an important factor in the etiology of vulvovaginitis in young girls, and the focus of health care during this period remains on external genital hygiene and disease prevention. It is important to pay attention to hygiene education and to develop good hygiene habits. If you’re not sure how to do this, you should learn how to wipe your vulva and anus correctly, and wipe from the perineum to the anus after a bowel movement to avoid fecal contamination of the vulva; wipe around the urethra with a soft tissue after urinating, and be gentle when wiping. Make it a habit to wash your vulva every day before bed, use a special basin or shower, the water should be scattered and soft when showering, too much water will stimulate the sexual organs, no need to use drugs to wash without medical advice. Children should wear whole crotch pants after walking, and try not to wear open crotch pants or play in mud or unclean water without pants to avoid vulva pollution or foreign objects accidentally entering the vagina. Girls should change their underwear daily, with soft, cotton underwear being the best. The more common clinical lacerations of the vulvar skin can occur on the labia, mons pubis, and perineum, and the collision of the vulva with hard objects such as tables and chairs, rocks, or bicycles can cause vulvar hematomas and hymenal lacerations. It is not uncommon for young girls to put glass balls, buttons, pen caps, straw sticks, etc. into the vagina on their own or by others out of curiosity. Therefore, it is important to check for foreign bodies in the vagina in case of untreated vaginitis.
