Retrograde Ejaculation
Retrograde ejaculation is a condition in which semen travels back into the
bladder instead of forward through the urethra.
What is going on in the body?
Normally, the bladder neck closes tightly during orgasm. This prevents semen
from travelling back into the bladder. The semen has nowhere to go but out of
the urethra and the tip of the penis. Damage to the bladder neck or neurologic
disorders may prevent it from closing properly.
What are the causes and risks of the condition?
The most common cause of retrograde ejaculation is
transurethral resection of the prostate. This is surgical removal
of prostate tissue through the urethra. Other causes include:
operations involving the abdomen, pelvis, or genitals
diabetes
multiple sclerosis, a progressive neurological disorder that can
disrupt nerve pathways to the bladder neck
some medications used to treat heart disease or high blood
pressure, which can relax the bladder neck
