What Makes Cervical Mucus Yellow

Page content

Vaginal discharge can vary in appearance, smell, and color; and you should be aware of these changes as they may be indications of abnormality. Typically, cervical mucus is clear without any distinct odor. A change in texture is caused by the normal processes of the reproductive system, but the color remains the same.

Yellow cervical mucus can be alarming to women as this is an unusual type of discharge. What makes cervical mucus yellow, then? The presence of infection is the primary reason behind a yellow cervical mucus. This change in color is usually accompanied by a foul odor. It is important to seek medical advice at the onset of these symptoms to obtain prompt treatment. This article explains the possible reasons why cervical mucus becomes yellow, as well as the appropriate actions to be done in the presence of each medical condition.


Cervicitis is the inflammation of the cervix caused by a number of factors, including having multiple sex partners, a history of sexually transmitted disease, an allergic reaction to spermicides and latex condoms, bacterial infection or overproduction of normal bacteria in the vagina. Cervicitis is a common gynecological infection that affects a number of women during their adult life.

Mild cervicitis typically has no symptoms; but indications of the illness is present in severe cases such as the following:

  • Vaginal bleeding after sexual intercourse, between menstrual periods, and after menopause
  • Painful sexual intercourse
  • Gray, white, or yellow vaginal discharge with foul odor
  • A feeling of heaviness in the pelvis

Simple cervicitis is treated with antibiotics or antifungal medications. The treatment options for advanced stages of cervicitis include laser treatment, cautery, and cryosurgery (freezing or cold cautery).


Trichomoniasis is a sexually-transmitted disease caused by the parasite Trichomonas Vaginalis. Trichomoniasis affects both men and women, but in the United States, it is common among women between the age 16 and 35. The parasite is spread in two ways: penis-to-vagina during sexual intercourse, or vulva-to-vulva contact.

Among the most common symptoms in women are the following:

  • Unusual vaginal discharge (yellow or greenish-yellow) with foul odor
  • Vaginal itching
  • Swelling of the vulva
  • Discomfort or pain during sexual intercourse
  • Itching of the inner thighs

Pelvic examination and pap smear are done to diagnose a patient with those symptoms. After confirmation of an illness, antibiotics are prescribed, such as Metronidazole, or Tinidazole. Engaging in sexual intercourse while undergoing treatment is discouraged, as this will cause further irritation.


Gonorrhea is a contagious disease caused by the bacterium called Neisseria Gonorrhoeae, and is transmitted through sexual intercourse with an infected person. Upon entry in the body, the bacteria can grow in several areas in the reproductive tract, such as the uterus, fallopian tubes, and the ovaries. It can also situate itself in the urethra, anus, mouth, and throat.

Symptoms are not evident to all infected persons; when symptoms do occur, they must be treated promptly. Those who have this illness experience the following:

  • Greenish-yellow or whitish vaginal discharge
  • Pain during sexual intercourse
  • Discomfort or pain in the lower abdomen
  • Inflammation or swelling of the vulva
  • Conjunctivitis
  • Burning and swollen glands in the throat (caused by oral sex with an infected partner)
  • Bleeding or spotting after sexual intercourse

Those who have the presence of gonorrhea symptoms should consult their doctors immediately. Since chlamydia and gonorrhea often occur at the same time, testing for both sexually-transmitted diseases must be done.

Once gonorrhea is detected at its early stage, treatment does not take for a long period of time. Antibiotics are usually prescribed, and adherence to the instructions in taking the medication must be followed carefully to ensure complete recovery. While undergoing treatment, patients are not advised to engage in sexual intercourse.
