Unexpected Menstrual-Like Symptoms in Males: Medical Evaluation Needed

Males cannot menstruate. If a male experiences bleeding from the urethra, rectum, or other orifice, or cyclical pelvic symptoms, this indicates a medical condition requiring prompt evaluation—not a "period."

Possible Causes of Genital/Rectal Bleeding in Males

• Urethral: Urethritis (STI, trauma), stricture, meatal stenosis, carcinoma.
• Rectal: Hemorrhoids, fissures, IBD, colorectal cancer, radiation proctitis.
• Urinary: Hematuria (stones, infection, bladder/kidney cancer).
• Skin: Perianal abscess, fistula, dermatoses.

Cyclical Pelvic Symptoms

• Prostatitis, pelvic floor dysfunction, interstitial cystitis can cause recurrent pain/urinary symptoms.
• Endometriosis is exceedingly rare in males (estrogen therapy, remnant Müllerian tissue).

Action

1. Do not self-treat with menstrual products.
2. See a urologist or primary care physician for history, exam, urinalysis, STI testing, imaging as indicated.
3. If transgender/nonbinary on gender-affirming hormones: discuss expected bleeding patterns with prescribing clinician.

Any unexplained bleeding warrants medical assessment. Early diagnosis improves outcomes.
