Transparent Vaginal Discharge: Everything You Need to Know

Last update: 05 June, 2023

Vaginal secretions are usually normal in women during their reproductive age. The color, consistency, and fluidity of the discharge can vary according to hormonal influence, pregnancy, and the presence of infections. Are you interested in learning more about transparent vaginal discharge? Below, we’ll tell you everything you need to know.

Vaginal discharge is a viscous, sticky, and thick or light liquid that’s expelled in the genital area and varies according to the woman’s menstrual cycle. Changes in these secretions offer a wide variety of information about the health of the female genitalia, so it’s vital to recognize what each type indicates.

What does the transparent vaginal discharge indicate?

Clear vaginal discharge is the most common form of vaginal discharge. This is usually translucent, fluid, and odorless, with a texture similar to that of egg white. Similarly, it occurs on a woman’s most fertile days and increases considerably during ovulation.

It’s also common to see this type of discharge in other phases of the menstrual cycle, and even during sexual intercourse, when it acts as a natural lubricant. It’s a defense mechanism that balances the vaginal flora and local health.

During the first days of the fertile period, the clear discharge can be more liquid, watery, and abundant, and it can even leave a woman’s underwear moist. Some women may notice a significant increase in libido during this period. In adolescents, this flow may indicate the proximity of menarche.

The composition of vaginal discharge is what determines its color and consistency. Under normal conditions, it’s made up of water, endometrial mucus, and secretions from the Bartholin glands, sebaceous, and sweat glands. In addition, it includes dead cells from the vagina and uterus, as well as bacteria from the intimate area.

Transparent flow features

Transparent vaginal discharge has several functions.
The female genitalia is kept lubricated and with a stable microbiota thanks to the fluids of the area.

Transparent vaginal discharge serves several functions in maintaining the intimate area. In general, it acts as a cleaning mechanism, removing and eliminating dead cells and the rest of the waste contained in the vaginal canal.

In the same way, it’s responsible for maintaining an adequate level of humidity and lubrication of the walls of the genitals. Some studies affirm that it allows for the regulation of vaginal pH and favors the growth of protective microorganisms, such as L actobacillus spp.

During ovulation, the body increases the production and secretion of vaginal discharge in order to promote fertilization. In this regard, the fluid secretion promotes the sliding and ascent of the sperm through the uterine canal, until it reaches the newly released ovum.

The relationship between vaginal discharge and hormonal changes

Female sex hormones are substances that act by regulating, stimulating, and inhibiting various processes that give rise to a woman’s menstrual cycle. In each of the phases of this cycle, it’s possible to observe changes in the color, quantity, and consistency of vaginal discharge.

Estrogen is the hormone that has the greatest effect on secretion production in the intimate area. In this regard, the increase in estrogen levels prior to ovulation is what promotes the appearance of transparent discharge. After the ovulatory phase, estrogen decreases and discharge becomes thicker.

Similarly, in the first and third trimesters of pregnancy, it’s possible to observe the expulsion of translucent vaginal discharge. However, during the second trimester, this phenomenon is very rare. It’s generally associated with a greater release of progesterone than estrogen in pregnancy.

When is vaginal discharge indicative of a disease?

A woman with vaginal itching.
When the characteristics of discharge change in terms of color, consistency, volume, and odor, a disease may be developing.

In most cases, normal vaginal discharge is clear, odorless, slimy, sticky or watery, and elastic. In this regard, the appearance of unusual changes in the odor, color, and consistency of the discharge may be indicative of a medical condition.

Studies estimate that 95% of vaginal infections are associated with variations in vaginal discharge, with trichomoniasis, candidiasis, and bacterial vaginosis being the most common causes. Similarly, gonorrhea and chlamydia are less common causes of changes in intimate secretions.

In bacterial vaginosis, the discharge is grayish-white with a characteristic fishy odor, accompanied by itching and difficulty urinating. On the other hand, in cases of candidiasis, vaginal discharge is white, thick, and lumpy. This is odorless and accompanied by redness in the area.

Additionally, trichomoniasis is a parasitic infection that produces a frothy and greenish-yellow discharge. This discharge usually causes redness, irritation, and itching in the genital region.

Warning signs of vaginal discharge

Transparent discharge is very common in women and doesn’t represent any disease. This usually becomes more evident in the fertile days before ovulation and during sexual intercourse. However, it’s important to be attentive to variations in vaginal discharge that could indicate the existence of a disease.

In this regard, it’s advisable to seek care with a gynecology specialist in the event of an abrupt increase in the amount of discharge and evidence of characteristic symptoms of vaginal infection. Additionally, bloody discharge outside of the menstrual period and lower abdominal pain are warning signs that require a prompt approach.
