Why does nothing come out when I pee (male)?

In men, this can be the result of an enlarged prostate or what is known as benign prostatic hyperplasia (BPH). This condition is usually due to age. As men get older their prostates enlarge and put pressure on the urethra which is the tube that controls the flow of semen and urine. This can create urinary complications including an increased urge to pee when the bladder isn't full resulting in very little urine or trouble with completely emptying the bladder.
