Sperm in urine is an uncommon problem, but it can be caused by both prostatitis and retrograde ejaculation. Both of these conditions can typically be treated, although they may cause discomfort or pain in the meantime. Sometimes it is hard to notice and diagnose semen in the urine since it is not a common issue, especially amongst young men.

One potential cause of sperm in urine is prostatitis. This is swelling or inflammation of the prostate gland, which helps in the manufacturing of semen. Certain medical conditions may lead to long-term and severe swelling of the prostate. During urination, the bladder contracts and bumps up against the swollen gland. This can cause a small amount of semen to be released at the same time as urine, or shortly after. Urine may appear cloudy if enough semen is present.

This swelling of the prostate gland can also occur if men fail to ejaculate often enough. Although this may take a while to occur, men who become aroused and fail to either engage in sexual intercourse or masturbation in order to achieve orgasm may have excess semen stored in the prostate gland. This is typically not a serious condition and is not considered full-blown prostatitis. The cure in this case is typically ejaculation.


In the former case, sperm in urine should be evaluated by a doctor. There are various forms of treatment for an inflamed prostate, although it may depend on the underlying cause. Serious medical conditions such as prostate cancer may need to be ruled out. Medications may be given to reduce swelling. If any other sexually related symptoms are present, these symptoms may also be investigated further.

Another condition which may cause sperm in urine is retrograde ejaculation. This is a condition in which semen moves backwards through the urethra into the bladder rather than out of the body. It is caused by a lack of bladder contractions which normally take place during ejaculation to keep urine and semen separate. Urine will often appear clouded after sex in men with this condition.

There are few treatments for retrograde ejaculation. Certain medications can be given to close off the bladder to prevent sperm in urine from occurring during ejaculation, but these are not always effective. Surgery can also be performed but this is not generally recommended because it is ineffective in most men. Having sex with a full bladder can help keep it from happening, but it may also make sex less enjoyable.

It's killing me. You know, after I urinate I see sperm and afterward I experience some pain in my penis and the testicles. This will develop into painful joints and muscles as well as the eyes. It's scaring me. What could be the problem?

Are you guys are talking about semen or a sperm? Today while urinating, three sperm came out of my penis. I'm so very scared. Please, someone answer me: is this common or just happening to me? One of them was broken in two, and the other two were complete. Their shape was similar to the picture above but their heads were white too. The size was between 1/2 to 3/4 inches. Please reply.

Last year I was referred to the doctor who seemed not to know what my problem was and I asked if smoking can cause this disorder. He said no yet did me smoking aggravate the situation?

I also have this problem sometimes when I urinate. I have some wet, sticky, colorless sperm also coming out, and sometimes white sperm.

I have had this for the last two years, I think. I have had tests for HIV and gave a urine sample for all STDs, but all the tests were negative and the doctor told me I had no STDs or infections. I don't understand why still I have discharge in my urine. Can someone tell me what I should do and which doctor I should see for this problem.

I have this problem. How can I solve this? Should I eat some specific foods or change my daily routine?

@burcidi-- Yes, that can happen. During a wet dream, sperm doesn't ejaculate as it would after intercourse or masturbation. Sperm will likely be remaining in the urethra which will be released while urinating. Masturbating will decrease the occurrence of this although it's not a problem otherwise.

Sperm in urine will be cloudy as you said and will usually foam up in the toilet.

If you however continue to experience this even when you don't have a wet dream, it could also be an infection and you should see your doctor in that case.

Is it normal to urinate cloudy urine (probably sperm) after a wet dream?

What happens if someone has retrograde ejaculation and loses sperm in urine? Will it effect his general health or fertility if it isn't treated?

Having sperm in urine doesn't sound like a very bad thing, as long as it's not associated with something like prostatitis and causes other symptoms. Am I wrong about this?
