is the passage of semen into the bladder rather than
out of the body through the urethra and penis. Prostate
cancer treatment, especially lymph node dissection,
may result in retrograde ejaculation. During lymph node
dissection, a surgeon removed the lymph nodes that are
next to the bladder. Removing these lymph nodes and
any surgery near the bladder, may name the urinary sphincter.
Once the urinary sphincter is damaged, the muscles no
longer seal the bladder during ejaculation. The semen
meets less resistance going backwards than forwards,
so the ejaculate enters the bladder. Retrograde ejaculation
is not harmful and will result in cloudiness of the
urine after sex or masturbation. Men who experience
retrograde ejaculation may still be able to father children
through retrieval of the sperm cells and the use of
in vitro fertilization.
