Leukorrhea or (leucorrhoea British English) is a thick, whitish or yellowish vaginal discharge. There are many causes of leukorrhea, the usual one being estrogen imbalance. The amount of discharge may increase due to vaginal infection or STDs, and also it may disappear and reappear from time to time, this discharge can keep occurring for years in which case it becomes more yellow and foul-smelling; it is usually a non-pathological symptom secondary to inflammatory conditions of vagina or cervix. Leukorrhea can be confirmed by finding >10 WBC under a microscope when examining vaginal fluid.〔Workowski, Kimberly A., and Stuart Berman. "Sexually Transmitted Diseases Treatment Guidelines, 2010."

Vaginal discharge is not abnormal, and causes of change in discharge include infection, malignancy, and hormonal changes. It sometimes occurs before a girl has her first period, and is considered a sign of puberty. Leukorrhea (or Leucorrhoea) is also known as trigomonasis and are cuased by trigomonads specifically trigomonas vaginalis. ==Physiologic leukorrhea== It is not a major issue but is to be resolved as soon as possible. It can be a natural defense mechanism that the vagina uses to maintain its chemical balance, as well as to preserve the flexibility of the vaginal tissue. The term "physiologic leukorrhea" is used to refer to leukorrhea due to estrogen stimulation. Leukorrhea may occur normally during pregnancy. This is caused by increased bloodflow to the vagina due to increased estrogen. Female infants may have leukorrhea for a short time after birth due to their in-uterine exposure to estrogen. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Leukorrhea」の詳細全文を読む スポンサード リンク
