Retrograde ejaculation is a condition in which semen travels back into the bladder instead of forward through the urethra.
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.
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:
Men with retrograde ejaculation have a very low volume of ejaculated semen.
A urine specimen is taken right after the man has an orgasm. If many sperm are found in the urine under the microscope, the diagnosis is made.
Retrograde ejaculation can cause male infertility, a condition in which a man is unable to impregnate a woman.
Retrograde ejaculation is not contagious, so there are no risks to others.
Many men can be treated with medications that tighten up the bladder neck, such as ephedrine. If this is not successful, sperm can be recovered from the bladder following orgasm for artificial insemination or for in vitro fertilization. The bladder may need to be rinsed out before and after orgasm to recover good sperm.
Some of the medications used to relax the bladder neck can cause arrhythmias, or irregular heartbeats.
No after treatment or long term monitoring is necessary.
