Introduction
Left lower abdominal pain in men is very likely a symptom of prostatodynia. Prostatodynia is a discomfort similar to chronic prostatitis, caused by spastic pain in the urethra, prostate, or the muscles of the perineum and pelvic floor. Patients with this condition typically exhibit marked tenderness in the levator ani muscles on both sides of the anus. Prostatodynia commonly affects middle-aged and young adults and presents with some symptoms of nonbacterial prostatitis, but without a history of urinary tract infection.
Urology outpatient visits are steadily increasing, and many male patients present with dull pain in the left lower abdomen. It is important to note that there are numerous potential causes of left lower abdominal pain in men, and early detection and prompt treatment are essential. So, what could be causing left lower abdominal pain in men?
What Causes Left Lower Abdominal Pain in Men?
Left lower abdominal pain in men is often a symptom of prostatodynia (prostate pain). Prostatodynia refers to discomfort resembling chronic prostatitis, caused by spastic pain in the urethra, prostate, perineum, or pelvic floor muscles. Patients typically exhibit marked tenderness upon palpation of the levator ani muscles on both sides of the anus. This condition commonly affects middle-aged and young adults and presents with some non-bacterial prostatitis-like symptoms—yet without a history of urinary tract infection. Bacterial cultures of the urethra, bladder, and prostate reveal no pathogenic microorganisms. The impact of prostatodynia on men’s health should not be underestimated; severe cases may even impair male fertility. Early intervention is critical. Left lower abdominal pain associated with prostatodynia is frequently accompanied by irritative voiding symptoms, including intermittent urgency, increased urinary frequency, nocturia, and dysuria.
Some urological infectious diseases—such as prostatitis and seminal vesiculitis—may spread along the vas deferens to the epididymis, resulting in compromised blood supply and infection. Frequent transurethral instrumentation and indwelling catheter use following prostatectomy can also lead to epididymitis and left lower abdominal pain. This may occur due to external compression exerted on the testicles, causing a sensation of pressure or squeezing. Additionally, overly frequent sexual activity between partners may trigger left lower abdominal pain—particularly among adolescents and unmarried individuals.
Patients should take precautions against cold exposure, maintain warmth, follow a light diet, avoid spicy and irritating foods, adhere to regular sleep-wake cycles, and ensure adequate rest. We hope this information proves helpful to you.
