Introduction
The transparent, viscous fluid discharging from the penis is most likely prostatic fluid and generally falls into the following categories:
1. During penile erection, a small amount of prostatic fluid may leak from the external urethral meatus prior to ejaculation. This is asymptomatic and appears as a colorless, transparent fluid requiring no specific intervention.
2. Prostatic fluid may also discharge from the external urethral meatus during daily activities.
Many men may suffer from urological conditions, yet due to the embarrassment associated with such issues, most choose not to seek medical treatment. What is the transparent fluid secreted by the penis?
What is the transparent fluid secreted by the penis?
The transparent, viscous fluid discharged from the penis is most likely prostatic fluid, and generally falls into the following categories: During penile erection—prior to ejaculation—a small amount of prostatic fluid may leak from the external urethral meatus. This is a normal physiological phenomenon, presenting as a colorless, transparent fluid without any clinical symptoms and requiring no specific intervention. Secondly, prostatic fluid may occasionally discharge from the external urethral meatus during daily life.

In most cases, however, such discharge is associated with prostatitis or other related disorders. Patients may experience urinary frequency, urgency, dysuria, and discomfort in the lower abdomen, perineum, or scrotum, along with other symptoms such as dampness. To confirm diagnosis, routine examinations—including complete blood count, urinalysis, color Doppler ultrasound, and prostatic fluid analysis—are recommended, followed by targeted treatment. Therapeutic approaches may include acupuncture, physical therapy, sitz baths, prostate massage, and pharmacotherapy. Additionally, upon penile erection or sexual stimulation, a white, transparent fluid may be observed discharging from the urethra.
This is a normal physiological occurrence. The transparent fluid is known as “bulbourethral gland secretion” (or pre-ejaculate), a component of semen produced by the bulbourethral (Cowper’s) glands. It serves as a natural lubricant during intercourse. Recent research has also indicated that this fluid may play a supportive role in sperm function. We hope this information proves helpful!
