What are the common causes of odorless vaginal discharge?

Odorless vaginal discharge is normal and healthy. It helps keep the vagina infection-free, prevents trauma during intercourse, and nourishes sperm on the way to the fallopian tubes. Normal vaginal discharge can vary in color and consistency, but should be clear, white, or tinted yellow.

Changes in vaginal secretions occur throughout the menstrual cycle. These come from both the cervix and the vaginal walls. Odorless vaginal discharge is also a result of sexual arousal. Many women also experience increased discharge during pregnancy.

After the menstrual period has ended, thick white vaginal discharge is normal. It is also normal not to notice any discharge. Vaginal discharge is also present after ovulation, before the next menstrual period begins. Its function is to rid the body of infectious material.

Around the time of ovulation, in the middle of the menstrual cycle, most women experience copious amounts of clear, stretchy vaginal discharge that has no odor. The purpose of this discharge is to nourish and protect the sperm, so that they can reach the egg released during ovulation. Normally, the vagina is acidic, which is hostile to fragile sperm. The vaginal discharge produced by the cervix during ovulation neutralizes the acidity. It also provides nourishment, and is similar in composition to semen. The vagina produces more odorless discharge during sexual arousal. This discharge is thin and watery and protects against injury during intercourse.

During pregnancy, a more odorless vaginal discharge may be experienced. This increase is caused by increased estrogen and blood flow to the vagina. As labor approaches, thick odorless vaginal discharge is expelled. This is a plug of mucus that has formed in the cervix to prevent infections from entering the uterus.

If odorless discharge is heavy, a panty liner can be used to relieve the sensation of wetness. Douches should never be used as they remove secretions that inhibit infection. A tampon should not be used to absorb the discharge, as there is a risk of toxic shock syndrome, a serious infection caused by staph.

Vaginal discharge that has an unpleasant odor indicates a problem. Yellow, green, or brown discharge can also be a problem, and any changes in the discharge should be reported to a healthcare professional.

Most women who have experienced puberty have vaginal discharge. After menopause, the drop in estrogen can cause this discharge to stop. This can cause itching and burning, painful intercourse, and an increased risk of infection. Women who experience a cessation of vaginal discharge should see their health care provider.
