Retrograde Ejaculation
Wed,26 October 2011
During normal ejaculation, semen is propelled forward through the urethra and out the tip of the penis. In men with retrograde ejaculation, the muscle at the opening of the bladder, which usually stops semen from entering the bladder during orgasm, does not close normally. This allows semen to flow back into the bladder. Therefore little or no semen is discharged from the penis during ejaculation, and the first urination after sex looks cloudy as the semen mixes into the urine. This uncommon condition is harmless.
What can cause retrograde ejaculation?
