    Testicular Biopsy

    How It Is Done

    This biopsy is done by a surgeon or a doctor who treats reproductive health problems in men (urologist) in the doctor's office, a day surgery clinic, or a hospital operating room.

    You will lie on your back on an examining table. The skin over your testicle is cleaned with an antiseptic solution, and the area around it is covered with sterile cloth. Your doctor will wear sterile gloves. It is very important that you do not touch this sterile area.

    A local anesthetic will be injected into the skin of the scrotum to numb (anesthetize) the area. Then a small incision is made through the skin, and a tiny piece of testicular tissue is removed with small scissors. A single stitch is used to close the incision in the testicle, and another stitch is used to close the incision in the skin. (Absorbable sutures are used so the stitches do not need to be removed.) The procedure is usually repeated on the other testicle. The scrotal area is then bandaged. You will be asked to wear an athletic supporter for several days after the procedure to help support the testicles while the incisions heal.

    If general anesthesia is used, you will be asleep during the procedure but the same method will be used.

    The biopsy usually takes 15 to 20 minutes. You will probably be advised to refrain from sexual activity for 1 to 2 weeks after the biopsy. You should avoid washing the area for several days.

    How It Feels

    You will feel a brief sting when the IV line is inserted or when the local anesthetic is injected. Other than that, the procedure should be painless.

    Your scrotum and testicles may be somewhat sore for 3 to 4 days after the biopsy and some bruising may be present. You may also notice a small amount of bleeding through the bandage, which is normal. Talk to your doctor about how much bleeding to expect.


    There is a slight risk of prolonged bleeding or infection from this procedure. There is no risk of erection problems or infertility as a result of this biopsy. If general anesthesia is used, there is a small risk of complications from anesthesia.

    After the biopsy

    Call your doctor immediately if you have:

    • Severe pain in your scrotum. Some mild discomfort is normal.
    • Severe swelling of your scrotum. Some mild swelling is normal.
    • A fever higher than 100°F (38°C).
    • Excessive bleeding through the bandage.
