QUESTION: I want to know how long after prostate biopsy is there blood in semen?


It is quite possible for someone to have blood in the urine or in the semen after performing a prostate biopsy. As prostate is a part of the genito-urinary system, while on biopsy, the doctors are damaging a little bit the prostate structure.

When you have blood in the semen, you have to see how much blood there is. For example, if you are having small spots of blood, then, do not worry, that blood is going to disappear in just a few days.

But, when there is a lot of blood in the semen, it will disappear in a few weeks or even a month. In addition, the presence and the amount of blood depend on the number of material taken from your prostate.

During an ordinary prostate biopsy, they will usually take only 6-8 pieces of your prostate from different parts of it. In some cases, is quite possible for the urologist to take 10-14 pieces from your prostate. This will cause the rupture of more blood vessels, leading to increased amount of blood in the semen.

  • If you notice blood in your semen, that does not mean that you have to avoid sexual intercourse. This is because the ejaculation will help you to clean the blood from your prostate.

  • Another possible way of cleaning the prostate from the blood is by increasing the amount of fluids taken. In this way, you are going to urinate more often and a lot; therefore, the urine will wash the blood from your prostate.

  • Besides this, you don’t have to worry about a prostate infection, if there are no symptoms like fever, fatigue, pain, chills and other. This is explained with the fact that after the prostate biopsy, the doctors will put you on a preventive treatment with antibiotics.

    It is good for you to look for the above-mentioned symptoms for when they are present, you can inform your doctor immediately.

    All the best!

    Prostate Biopsy
    by: James

    I had a prostate biopsy one week ago due to a nodule.

    They numbed the area initially, and then took 12 samples. I experienced minimal discomfort. Afterward for 24 hours I felt soreness in the area and felt tired.

    I saw blood when I urinated for about 2 times. Very little fecal blood. As for semen, every time I ejaculate there is plenty of blood to be seen.

    I was told by the physician that I would see blood in the semen for up to 4 to 6 weeks.

    Ejaculation and drinking plenty of water would help to clear the blood from the prostate area.

    Seeing the blood in the semen concerns me, but I understand why it is there.

    I had a biopsy 1 week ago, lucky from what I've read that I had a general, no pain afterwards, very little blood in the urine. But semen is like pure bright red blood, no white at all. Is this normal?

    Undergoing a Biopsy
    by: Anonymous

    I had a Biopsy two weeks ago and had pain walking for only one day, so far the only symptoms i have now is blood in my seman which is quite alarming.

    i am hoping this will soon go away because not only is this freaking me out but my wife as well, i may also add my urologing did not advise me of how long the blood would last so i could prepair myself for this.

    My advise is for all to ask about blood coming from urine and ejaculation when undergoing a biopsy.

    Prostate Biopsy
    by: Anonymous

    I had a biopsy a few weeks ago.  Had I known then what I know now I would have refused to have it done.  

    What ever it was (probe) that was put inside me made me feel like I was being torn apart.  The injection of local anaesthetic was painful but tolerable but the actual taking of the samples had me needing to be peeled off the ceiling because of the pain.

    (And no I am not a feeble minded person _ I once drove myself to a hospital with a shattered ankle bone so I know I can tolerate some levels of pain but this was quite ferocious)

    After the procedure I left the hospital straight away, I just wanted to get out of there.  For four days I had a miserable time with a great deal of pain 'inside' me and a lot of pain where the probe had entered.  

    There was blood (a lot) and even lumps of something in my urine and passing water was very painful and still is.

    The pain from the procedure has calmed down but I am not completely free of discomfort.

    Thank goodness I refused point blank to both my GP and the doctor doing the biopsy to their demands to physically 'examine' me. The probe was dreadful enough and I will never have another test of any sort that requires anything inside me.

    Going to the bathroom is till uncomfortable after well over a week.  I know there are other techniques that can be used for the biopsy and I would recommend anyone needing a biopsy to ask their doctor about this and, having had the biopsy and being told upon refusing the physical exam that the biopsy is the main diagnostic tool anyway I would challenge any man to ask their doctor why they think they have to do this and how they think it will help a diagnosis if they are going to tear you apart with a biopsy anyway.

    Modern medicine has much more sophisticated techniques that some medieval finger inside you that isn't going to tell them too much anyway. I am glad at least I refused that but I wish I had refused the biopsy too.

    semen blood
    by: ARow

    QUESTION: What about if you have blood in your semen but you did not take the prostate biopsy, and still your not in the age of 45 to 50?

    ANSWER: Hi Arow,

    There are many factors causing blood in semen in young patients. They include benign factors (i.e. infection, or urethra stones, etc) and malign (tumors or metastatic cancers). Your doctor will find your specific cause.
