Retrograde ejaculation is a condition in which semen enters the bladder instead of exiting through the penis during orgasm. As a result, a man may notice little or no semen coming out, even though orgasm can still occur. ^[1][2]

Although the condition is not usually dangerous, it can be emotionally distressing, especially when fertility is a concern. Some men first notice it after prostate or bladder neck surgery, while others develop it in association with diabetes, nerve problems, or medication use. ^[1][2]

What are the symptoms?

The main symptom is very low semen volume or absence of visible semen during ejaculation. Cloudy urine after orgasm can occur because semen mixes with urine in the bladder. ^[1][2]

What causes it?

Normally, the bladder neck closes during ejaculation to prevent semen from flowing backward. In retrograde ejaculation, that mechanism does not work effectively. Causes can include prostate or bladder neck surgery, diabetes-related nerve damage, spinal cord injury, multiple sclerosis, and certain medications. ^[1][2]

Does it affect sexual pleasure or fertility?

Many men with retrograde ejaculation can still achieve erection and orgasm. However, fertility can be reduced because semen is not being delivered normally during intercourse. ^[1][2]

How is it diagnosed?

Diagnosis begins with history taking and physical examination. A urine sample collected after orgasm may show sperm in the urine, which supports the diagnosis. ^[1][2]

What are the treatment options?

Treatment depends on the cause and on whether fertility is a goal. If a medication is contributing, adjusting it may help in selected cases. Certain medications can be used to improve closure of the bladder neck in some patients. ^[1][2]

When should you see a doctor?

Evaluation is reasonable if semen volume has changed noticeably, if orgasms are consistently “dry,” or if there are fertility concerns. ^[1][2]

FAQ

Is retrograde ejaculation dangerous?

Can medications cause it?

Yes. Some medications can contribute, and medication review is an important part of evaluation. ^[1][2]

When should fertility be discussed?

If conception is a goal and semen volume is low or absent, fertility planning should be discussed early. ^[1][2]
