What causes white, viscous discharge from the glans penis?

White, viscous discharge from the glans penis may result from a Candida albicans infection secondary to phimosis (excessively long or tight foreskin). In such cases, surgical removal of the redundant foreskin (circumcision) may be necessary. Alternatively, the discharge could indicate balanitis (inflammation of the glans) or prostatitis. Balanitis is commonly caused by bacterial infection and inadequate penile hygiene. It can be treated with anti-inflammatory or antimicrobial medications. Prostatitis, meanwhile, typically presents with urinary symptoms—including frequent urination, urgency, dysuria—and may require treatment with cephalosporin antibiotics.

What Causes White, Viscous Discharge from the Glans Penis?

1. Balanitis

White, viscous discharge from the glans is a common and distressing symptom among many men—often attributable to balanitis. Non-infectious causes frequently involve phimosis combined with poor hygiene, leading to accumulation of smegma (a mixture of desquamated epithelial cells, sebum, and moisture) between the foreskin and glans. This buildup irritates the local foreskin and mucosal tissues, triggering inflammation.

2. Prostatitis

In certain cases, white, viscous discharge from the glans may raise initial suspicion of prostatitis. Typical manifestations include urinary frequency, urgency, dysuria, incomplete bladder emptying, urethral discharge of white, viscous fluid, discomfort in the lower abdomen, perineum, or testicles, and “dripping white” (i.e., spontaneous discharge of whitish fluid from the urethral meatus). Diagnosis can be confirmed at a hospital via urinalysis, urethral secretion testing, and prostate fluid analysis—enabling timely, targeted treatment.

3. Sexually Transmitted Infections (STIs)

White, viscous discharge from the glans may also stem from unprotected sexual intercourse, resulting in infection with pathogens such as Candida albicans, Trichomonas vaginalis, Chlamydia trachomatis, Mycoplasma species, Neisseria gonorrhoeae, or other bacteria.

4. Phimosis

Phimosis leads to retention of residual sweat, urine, and sebum beneath the foreskin, forming foul-smelling, white smegma. This substance readily irritates the glans and coronal sulcus, predisposing individuals to balanoposthitis (inflammation of both glans and foreskin). Moreover, if recent unprotected sexual contact has occurred, fungal infections such as candidiasis must also be considered. Prompt consultation at a specialized medical facility is strongly advised. From both infection-prevention and sexual health perspectives, early circumcision is recommended for confirmed phimosis.
