What is the black color in the vaginal discharge?

Normal women will have leucorrhea after puberty. Normal leucorrhea is white or transparent, somewhat sticky, has no odor, and is in relatively small amounts. However, some women’s leucorrhea is black in color and has a tofu-like consistency. What’s going on? Everyone must pay attention to this, your leucorrhea is abnormal. Now let me explain to you why there is black substance in leucorrhea.

Leucorrhea is a sticky white liquid that flows out of the vagina of women. It is a mixture of secretions from the Bartholin's glands, cervical glands, endometrium, exudate from the vaginal mucosa, and desquamated vaginal epithelial cells. Leucorrhea contains lactobacillus, lysozyme and antibodies, so it has the effect of inhibiting bacterial growth. After marriage, leucorrhea can also lubricate the vagina and facilitate sexual intercourse.

The formation of leucorrhea is closely related to estrogen, so pre-pubertal girls generally do not have leucorrhea. After puberty, the ovaries begin to develop and secrete estrogen to promote the development of the reproductive organs, and leucorrhea begins to appear at this time. During each menstrual cycle, the quality and quantity of leucorrhea changes as the secretion of estrogen varies.

Generally, the secretion of estrogen reaches its peak between two menstrual periods (equivalent to the ovulation period). Excessive estrogen stimulates the cervical glands to secrete more mucus, so the leucorrhea at this time is abundant, transparent, sticky like egg white, and can be pulled into threads, and the vulva feels moist. After the ovulation of the follicle, progesterone increases and inhibits the secretion of cervical mucus. At this time, the amount of leucorrhea is small and thick.

In the few days before and after menstruation, due to pelvic congestion, vaginal exudate increases, and leucorrhea also increases slightly. Because it contains more exfoliated cells, the leucorrhea is turbid. In addition, vaginal discharge increases after pregnancy, during sexual excitement, and after sexual intercourse.

The above is the answer to the question of why there is black color in leucorrhea. Not only is black vaginal discharge a symptom of gynecological inflammation, but cold body is also a major factor causing black vaginal discharge, so we need to take care of our body. In daily life, we should wash our underwear frequently. It is recommended to wear cotton underwear to avoid abnormal leucorrhea. I believe that after a period of treatment, this type of problem will gradually improve.
