During adolescence, the amount of estrogen secreted by ovaries begins to fluctuate periodically. When menstruation comes, the female estrogen level decreases. With the cessation of menstruation, its level will gradually increase, reaching the highest level the day before ovulation. Under the stimulation of estrogen, the cervical gland will secrete a large number of egg white leucorrhea. However, the decrease of estrogen level after ovulation will lead to the shedding of endometrial small pieces and cause bleeding. So some adolescent women will find a little bloodshot in leucorrhea. These are actually normal manifestations of adolescent girls' development, not pathological reactions.
Normal leucorrhea is mostly milky white or colorless and transparent, with slight fishy smell or tasteless. Puberty leucorrhea is influenced by estrogen, which changes periodically, sometimes increasing and sometimes decreasing. This is a normal phenomenon, don't mind. When girls ovulate, the amount of leucorrhea is relatively transparent, while at other times it is less and sticky. In the first three or four days of menstruation, pelvic congestion increases vaginal exudate, and more vaginal epithelial cells fall off during metabolism, so leucorrhea is more turbid and thick. Adolescent female reproductive organs develop very vigorously, so the production of leucorrhea will increase.
Normal female reproductive tract has its own defense mechanism to resist the invasion of external adverse factors. There are aerobic bacteria and anaerobic bacteria in the vagina of healthy women, forming normal vaginal flora. Among them, Lactobacillus is absolutely dominant, which produces lactic acid by decomposing glycogen in vaginal epithelial cells, so that the vagina is in a weak acid environment, thus inhibiting the excessive reproduction of pathogenic bacteria. Under normal circumstances, the labia minora is connected together, and the front and rear walls of the vagina are also close together, which plays the role of mechanical barrier; The mucus plug in the cervix can also prevent bacteria from moving upward and invading.
