Hello,
Difficulty in urinating in males can be due to obstruction due to enlarged prostate due to benign prostatic hypertrophy (often called BPH) or infection of the prostate( prostatitis), any blockage in the flow of urine like any scar tissue, injury (as in a car wreck or bad fall), blood clots, infection, tumors in the pelvic region, and stones, infection or due to disruption of the delicate and complex system of nerves that connects the
urinary tract with the brain and the nervous system.
