Blood in semen

Blood in semen: This often triggers fear in men! This is often unfounded.

Many men are frightened when suddenly appear in the blood in sperm. The fear is often unfounded. Researchers have found that the cause is harmless in most cases.  Anyone who thinks of cancer or a venereal disease is usually wrong. The sight is worse than the cause. Only rarely does bloody sperm have to do with a dangerous disease.


In this article you will learn all about the topic  bloody sperm as well as the possible causes, symptoms and treatment options.

Blood in semen, what does that mean?

Sperm with blood is medically referred to as hemospermia or hematospermia. Due to the addition of blood to the sperm, it turns pink to dark red and sometimes brownish. Most men do not even notice hemospermia, as it usually occurs only once or sporadically. Only in rare cases does blood in semen occur chronically. In addition, haemospermia occurs predominantly in men between the ages of 30 and 40. Only in around 10 to 30 percent of cases is blood in the sperm the cause of another disease. Otherwise, hemospermia is completely harmless.

differences in hemospermia: micro- and macrohemospermia

The seminal secretion is formed in the prostate and serves to transport and protect the sperm. The production of sperm takes place in the testicles. There they mature in the epididymis until they shoot out of the urethra together with the seminal secretion as ejaculate during ejaculation. The ejaculate is normally free of blood or only a little blood, so that it is not visible to the human eye and can only be detected in the laboratory. Doctors then speak of microhaematospermia. If the blood in the sperm is visible and therefore turns reddish, doctors call it macrohaematospermia.

How is blood produced in sperm?

Semen which is light red in color and in which light reddish streaks are visible comes from burst veins in the urethra or glans. If the ejaculate is dark red or brownish, it is older blood that has been in the sperm for quite some time and probably comes from the prostate or testicles. There is no testicular pain or stinging in the penis. The occurrence of blood in the sperm is in many cases not associated with pain. However, if the cause is inflammation, hemospermia can be painful.

From what age does hemospermia occur?

blood in semen can meet all men. Hemospermia is most common in the 30 to 40-year-old age group. But it can also occur in younger men. Less often older men suffer from bloody sperm. As far as the total number of diseases is concerned, urologists report many cases every year because hemospermia occurs very often. It is estimated that every second man has had blood in his ejaculate at least once in his life.

Blood in semen: These are possible causes!

As I mentioned, blood in sperm doesn’t always have a cause. In about half of the cases, doctors find no cause after comprehensive diagnostics. Therefore, this type of hemospermia is called idiopathic hematospermia . The symptoms disappear on their own after a short time. Those affected do not have to do anything else and do not have to fear any consequences.

If a disease is responsible for bloody sperm, it is usually harmless and can be treated without any problems. Only about 1-3 percent of men who complain of bloody ejaculate have a dangerous disease or inflammation.

The possible diseases that cause bloody semen:

Now you can find out which triggers are responsible for blood in the sperm.

  • Inflammation: Bloody sperm is mostly caused by inflammation. This can be inflammation of the prostate or urethra and the epididymis. It is caused by an infection or a sexually transmitted disease.
  • Mechanical damage: After a prostate biopsy examination or an operation, for example, an operation on the hemorrhoids, blood may appear in the semen. Long, intense and violent sex as well as certain erotic practices, such as the insertion of objects into the urethra, can also cause injuries, making the sperm bloody.
  • Stones, cysts and organic damage: Sometimes men suffer from a stone formation in the prostate or seminal vesicles. Like kidney stones, these are associated with bleeding and pain. When stones form, they lead to a narrowing of the vas deferens and urethra and to bloody ejaculate. Other triggers include dilated veins, cysts or diverticula in the prostate, urethra and vas deferens. A prostatic hyperplasia can also be the cause of bloody semen. Doctors have found that general symptoms such as high blood pressure, blood clotting or damage to the liver can also cause blood in the seminal fluid.
  • Malignant disease: In very few cases, cancer is the cause of blood in the semen, such as carcinoma or testicular cancer.
  • Non-organic causes: If after an examination a disease or inflammation can be excluded as a cause, it is possible that the blood in the sperm was caused by stress, anxiety, psychological problems or partnership problems.


Blood in semen is not contagious and mostly without consequences. However, if the man is infected with HIV, no unprotected sexual intercourse may take place. Because HIV is transmitted through blood and sperm.

Symptoms that may occur in connection with hemospermia

Usually, there are no other symptoms or pain. However, if a particular disease is responsible for bloody and lumpy sperm, other symptoms may occur. If these symptoms appear, you should not postpone your visit to the doctor, as this is a finding that needs clarification:


  • a weak urine stream increased urination
  • Pain during urination
  • Pain during masturbation
  • groin pain
  • back pain
  • diarrhea
  • Testicular pain
  • Abdominal and kidney pain
  • Puncture and pulling in the penis

treatment of bloody ejaculate

Usually no treatment is necessary. The symptoms subside after a few days. Taking medication is also not necessary. However, if the symptoms do not subside by themselves, or if there is a lot of blood in the sperm, we advise you to visit a doctor. In this way, health damages and risks can be avoided. If an inflammation is the cause of bloody sperm, it can, if not treated in time, lead to infertility . With the other diseases listed above, the therapy depends on the respective causes. If the penis is injured, sex and masturbation should be avoided for a while. If the bloody ejaculate comes from prostatitis caused by bacteria and viruses, treatment with antibiotics.

You can do this if you discover bloody sperm in your body

If the cause of the bloody sperm cannot be clarified and there is no serious illness behind it, but rather a psychic problem or stress is responsible, you can alleviate the symptoms in a natural way with some household remedies or go to a non-medical practitioner. Medicinal plants have proved to be particularly effective. These include pumpkin seeds, rye pollen, tree bark, saw palmetto fruits or root extracts.

You also have the opportunity to prevent bloody sperm: among other things, you should refrain from dangerous sexual practices, heavy alcohol consumption and smoking, eat a healthy and varied diet and do enough exercise. If you suffer from poor blood circulation, it is important that you have it treated, as it can have a negative effect on sex and ejaculation and can also lead to bloody ejaculate.

The doctor will perform these tests!

If you suspect that disease is the cause of the blood in the semen, you should undergo an examination. The doctor will first contact you tofind out what symptoms you are suffering from and to ask you about the bloody ejaculate. On the basis of these questions, he can already draw the first conclusions.

He will then palpate you and examine your penis and check it for visible changes and swelling. He will also look at the testicles and epididymis and test your pain reaction. It is also possible for him to palpate the careginal gland and perform a digital ultrasound examination. Irregularities and swelling of the prostate can thus be easily detected. In rare cases, for example, when cancer or tumor is suspected, a magnetic resonance tomographit is used.

In addition, the doctor carries out some laboratory tests and analyses the urine, the sperm as well as the blood count and the blood values.
