After the girl enters adolescence, the ovary begins to develop and secrete estrogen to promote the development of the whole body (including the breast and internal and external genitalia). In the development of both genitalia at the same time, began to appear leucorrhea.

Leucorrhea is a sign that the female body begins to develop and mature. Normal leucorrhea is white, odorless, non-irritating, was egg white or thin paste. Sources of leucorrhea, including normal uterus and fallopian tubes secreted by a small amount of liquid, mucus secretions within the cervix mucus, is the main source of leucorrhea, and vaginal submucosal capillary exudate and mixed shedding epithelium Cells, vestibular gland openings secreted mucus; little labia sebaceous glands secrete a small amount of sebum.

Leucorrhea has an important role against germs invasion. Usually, the girl vagina parasites with a large number of "vaginal bacteria", it can break down glycogen in vaginal epithelial cells, vaginal fluid was acidic, so that foreign pathogens have no place to survive. However, vaginal bacteria can not grow in a dry environment, to keep moist to grow vigorously. Girls leucorrhea generate more vagina can maintain a certain degree of moisture, it can effectively prevent the germs invasion. Cervical mouth is usually covered with a thick layer of alkaline solution, but also to prevent infection of a "checkpoint", some are not afraid of acid bacteria, even if lucky enough to pass the vagina, will be exterminated in the cervix outside.

The quality and quantity of leucorrhea change with the menstrual cycle, but also with the estrogen levels and pelvic, uterine congestion degree. Usually around the next menstrual cramps on the first 14 days or so, that is, ovulation (at this time the highest level of estrogen) and within 3 to 4 days before and after menstruation (pelvic, uterine hyperemia), leucorrhea than usual increase. In addition, manual labor or long-distance travel, due to the strong secretion of endocervical cells, leucorrhea will increase.

Adolescent girls should not pay attention to leucorrhea. As the saying goes, "ten women and nine belts", every healthy woman is more or less some leucorrhea, this is a normal physiological phenomenon. If you have not seen adolescent vaginal discharge, this is an anomaly, and should be vigilant suffering from hymen ataxia or ovarian dysplasia and other diseases. If the leucorrhea color change, the number increased, or leucorrhea mixed with sepsis, or even smell, suggesting that there may be genital lesions, you must seek medical treatment.

The production of leucorrhea does bring some troubles to the girls. First, the choice of underwear is a problem. Select underwear pants fabric with cotton, silk as well, light color, cotton fabric breathable, moisture absorption, and silk fabric wear comfortable. Women in the menstrual period or usual vaginal discharge are more, and menstrual blood and secretions color, size and smell can reflect the status of women's health. If wearing red or with large patterns underwear, menstrual blood or secretions contaminated on it, it is not easy to distinguish. Therefore, girls should wear white or light yellow, light patterns and other light-colored underwear.

Girls in the choice of underwear and wearing underwear, easy careless. At this time, you need to remind and teach the mother.

Do not buy chemical fiber underwear

Chemical fiber underwear more fashionable, better plastic effect, which is a big advantage, however, but also brought a negative effect. Because of its poor ventilation, it helps to breed bacteria and cause odor, at the same time, human skin susceptible to its allergies, it is more likely to cause diseases such as vaginitis, urethritis; In addition, although its tight plastic effect is good, At the same time, it will also affect the development of the reproductive organs of girls who have not yet developed completely, such as causing deformation of the genitalia, which is worth the candle.

2. New underwear to be cleaned

Garment factories in the production of underwear process, commonly used formaldehyde resin, ion resins, brighteners and other chemical additives for processing, in order to achieve shrinkproof, whitening, smooth, beautiful purpose.

3. Do not turn over the underwear to dry

4. To change frequently wash sun underwear

Because underwear personal, so the body's skin sweat will penetrate into the underwear. Perspiration sweat left in underwear for a long time, it will make clothes discolored and deteriorated, and hinder the excretion of the skin surface metabolites and volatilization. Long time do not change underwear, sweat infiltrated in underwear, secretions, etc. conducive to microbial growth, leading to skin diseases.

5 underwear should be loose and comfortable

6. Do not spray underpants spices

Female vaginal discharge with a certain smell, if the underwear texture is not very satisfactory, combined with the sweat mixed, easy to smell. Some girls are afraid of peculiar smell, then in the underwear spraying perfume or toilet water and other deodorant, it is unscientific, because it is easy to cause genital skin allergies.
